Instrument Calibration

Whether an instrument warns and/ oralarms at the proper time depends on itsability to translate the quantity of gas itdetects into an accurate reading.“Calibration” refers to an instrument’smeasurement accuracy relative to aknown concentration of gas. Gasdetectors perform relativemeasurements: rather thanindependently assessing the quantity ofgas present, they measure theconcentration of the air sample and thencompare it to the known concentration ofthe gas that the instrument is configuredto sample. This “known concentration”serves as the instrument’s measurementscale, or reference point.

If the instrument’s reference point hasmoved, then its reading will also move.This is called “calibration drift” and ithappens to most instruments over time.(Common causes of calibration driftinclude the normal degradation ofsensors, exposure of the sensor topoisons, and harsh operating conditions.)

When an instrument experiencescalibration drift it can still measure thequantity of gas present, but it cannotconvert it into an accurate numericalreading. Regular calibration with acertified standard gas concentrationupdates the instrument’s reference point,re-enabling it to produce accuratereadings.

There are two methods of verifyinginstrument calibration: through afunctional or “bump” test (or span check)or by performing a full calibration. Each isappropriate under certain conditions.

Bump (or Span) CheckA bump check is a means of verifyingcalibration by exposing the instrument toa known concentration of test gas. Theinstrument reading is then compared tothe actual quantity of gas present (asindicated on the cylinder). If theinstrument’s response is within anacceptable range of the actualconcentration then its calibration isverified. When performing a bump test,the test gas concentration should be highenough to trigger the instrument alarm. Ifthe bump test results are not within theacceptable range, then a full calibrationmust be performed.

Full CalibrationA full calibration is the adjustment of theinstrument’s reading to coincide withknown concentrations (generally acertified standard) of zero and spangases, to compensate for calibrationdrift. In most cases, a full calibration isonly necessary when an instrument doesnot pass the bump test (or after it hasbeen serviced).

Zero CheckA zero check is performed to verify thatthe instrument reads true zero (alsoreferred to as the “baseline”) in anenvironment in which no amount oftarget gas is present. Common situationsin which a zero check is performedinclude:• after exposure of the sensor to a

sensor contaminant• after the sensor has been exposed

to a very high concentration of thetarget gas

• as the sensor ages, since it maygradually drift

• after the unit has operated in varyingbackground conditions (e.g. humiditylevels)

• after exposure to extreme conditions(e.g. high temperature or humidity)

If the instrument fails the zero check,then a zero adjustment—which sets the instrument to true zero—should be performed.

Frequency of CalibrationThe frequency of calibration depends onthe sensor’s operating time, conditions ofuse (including chemical exposure) anduser experience with the instrument.New sensors should be calibrated moreoften until the calibration records provesensor stability. The calibrationfrequency can then be reduced to theschedule set by the safety officer or plantmanager. Before calibrating the sensors,it is good practice to apply power to theunit to allow the sensor to adapt to thenew environment. Sensors should bepowered at least one full hour before anycalibration attempt is made.

MSA Guide to Gas Sensor Selection and PlacementIn general, when placing sensors thefollowing principles should be considered:

• Place sensors in areas where the aircurrents are likely to produce the highestgas concentration, including areas wheregas buildup is likely, such as corners orstopping points of moving devices thatrelease gas.

• If you are attempting to take arepresentative room sample, do not placesensors near entrances or fresh air vents(because the sample concentration will be diluted by incoming air) unless there is a need to sample that specific area ofthe room.

• Place sensors close to the possiblegas/leak source.

• Place combustible gas sensors betweenthe potential leak and the ignition source.

• Place toxic gas and oxygen sensorsbetween the potential leak and thepopulated area, and in the workers’breathing zone.

• Consider ease of access to the sensor for maintenance requirements, such asperiodic calibration. Use a remote sensorfor high or inaccessible locations.

• Avoid mounting sensors near radiotransmitters or other RFI-producingsources (e.g., welding activity andinduction heaters), to reduce possible RF interference.

• Avoid locations where airborne particlesmay coat or contaminate the sensor, suchas paint booths.

• Install sensors in a position that preventswater or dust accumulation on the sensorhead (which may impede the diffusion ofgas into the sensor). The preferred positionis facing downward, but horizontalplacement is also acceptable.

• Facility air intakes are generally goodlocations for sensors.

• Ensure that the entire area in question issufficiently monitored, including little-usedareas such as closets, warehouses andother storage areas.

• Factor in the vapor density of themonitored gases when compared to air.


STEP 1: To determine where toplace sensors, perform ananalysis of the potential gashazards in your facility.

STEP 2: Create drawingsindicating all potential leak sites,as well as the severity of eachsite’s hazard potential.

There are two main categories ofhazardous locations:

A. Potential gas dischargepoints. These are placeswhere hazardous gases maybe released, such as valvestem seals, gaskets,compression fittings andexpansion joints.

B. Potential contact areas.These are places wherehazardous gases mayendanger workers, or damageequipment or property.Examples include populatedareas, confined spaces, pits,stairwells, crawl spaces,shelters, and residential,business and industrialenvironments located nearby.

STEP 3: Since gases do notalways behave in the same way,take air flow conditions, as well as potential gas pockets, intoconsideration before placingsensors. MSA smoke tubes (P/N 458481) can be useful inmeasuring the direction and rateof air flow to determine areaswhere gases may accumulate.

Gas Density and Sensor Placement

Gases Gas Density Sensor Placement

carbon dioxide, heavy hydrocarbons

greater than air closer to the ground

hydrogen, methane less than air near the ceiling

carbon monoxie, nitrogen similar to air according to air current path,at or near breathing level(usually 4 to 6 ft. from floor)

Combustible Gas Sensors• Hydrogen and methane are lighter than

air, so place sensors near the ceiling, andin ceiling corners where pockets of airmay collect.

• For electric motor monitoring, placesensors near the ignition source.

• Gasoline is heavier than air, so placesensors near—but not directly on—the floor.

• When monitoring multiple combustiblegases, calibrate the instrument for theleast sensitive gas.

Toxic & Oxygen Gas Sensors• Place carbon monoxide and carbon

dioxide sensors for indoor air qualitymonitoring near air intake ducts.

• In general, in occupied areas (e.g.,confined spaces) monitor for oxygen and toxic gases in the workers’ breathingzone (4-6 ft.). This will vary, depending on whether the density of the gas isheavier, the same as, or lighter than, air or oxygen.

Toxic & Combustible Sensors• Place sensors near the potential release

source for process monitoringapplications (e.g., pipelines, valves).

• Gas cylinder storage areas: If they areventilated, place sensors near the returnair vent.

• Acid/ solvent drum storage areas: Thesegases are heavier than air (e.g., heavyhydrocarbons) so place sensors close tothe ground and in corners where air maycollect in pockets.

• If the hazard is outside, place sensorsnear the air intake for both combustibleand toxic gas monitoring; if the hazard isinside, place sensors near the exhaust.

• Some gases may collect in pockets inroom corners, at both floor and ceilinglevels. Place sensors in these areas ifnecessary.

Refrigerant Monitor Placement• ASHRAE 15 states that a refrigerant

monitor capable of detecting the TLV fora refrigerant gas must be installed in amechanical equipment room.

• Place the end of the sample line in thelocation most likely to develop arefrigerant gas leak or spill. Such areas

include valves, fittings and the chilleritself. Also, monitor any refrigerantstorage location. It is good practice tokeep all sampling lines as short aspossible when an aspirated or pumpedsampling system is used.

• Since most refrigerant gases are heavierthan air, monitor these gases close to thefloor. Any pits, stairwells or trenches arelikely to fill with refrigerant gas before the main area. It may be necessary tomonitor these locations for refrigerant gas.

• If ventilation exists in the chiller room,MSA smoke tubes (P/N 458481) will helpto determine the most appropriate gasmonitoring locations.

• Monitor displays can be placed justoutside the doorway of the monitoredarea, enabling personnel to check thestatus before entering the area.

• ASHRAE Standard 147P states thefollowing:4.8 Refrigerant Monitor. On largerefrigerating systems for which arefrigerant monitor is required perASHRAE 15, a refrigerant monitorcapable of detecting refrigerantconcentrations of 1 ppm by volume orless shall be used to provide earlywarning of leaks.

It is not intended to serve as an exhaustive review of all considerations. Due to the large numberof variables present, each site should be considered individually by a trained professional. The services of anIndustrial Hygienist (CIH) or Safety Professional (CSP) should be considered if an onsite survey is required.
