Environmental Quality Meter with Sound

The Environmental Quality Meter with Sound is a 5-in-1 instrument that functions as a:

- Sound-Level Meter – measures sound levels (dB) simulating the human ear using the A Weighting and Fast Time Weighting.

- Light Meter – measures light (lux) using an exclusive photodiode and color-correction-filter, light sensor.

- Anemometer – measures wind-speed using a low-friction, ball wheel design.- Hygrometer – measures relative humidity using a high-precision humidity sensor.- Thermometer – measures temperature using standard Type-K thermocouple.

Nikon Coolpix 800 digital camera with fish-eye lens

- A super wide-angle of 180 degrees gets everything in the frame – great for giving context.

- The distortions resulting from such a wide angle can be used to artistic or humorous effect.

- Combine the incredibly short focal length with a small aperture, and even objects touching the lens can be in focus.

- A huge field of view combined with a relatively small camera means you can get very unusual perspectives on small or inaccessible spaces.

- A fisheye lens lets you easily capture full spherical panoramas in just a few shots.

Psychro-Dyne

This portable psychrometer indicates wet and dry bulb temperatures for relative humidity and dewpoint determinations. Housed in a high-impact case, the unit consists of a pair of matched thermometers, magnetic fan motor, plastic water bottle, illuminating lamp, psychrometric slide rule and spare parts kit. No whirling of the instrument is required to obtain readings. A miniature fan provides constant air motion over the thermometers. Humidity is determined from the psychrometric tables included with the instrument.

Testo 400 and Testo 480 Climate Measuring Instrument

The testo 400 and testo 480 is a measuring instrument for measuring climate-related parameters. The testo 400 and testo 480 is ideal for comfort level measurements for the workplace evaluation and flow measurements in and at ventilation and air-conditioning systems. Depending on the measurement parameter to be measured, certain probes or sensors must be plugged into the instrument.

You can customize measuring programs to match the relevant measuring task (e.g. continuous or punctual measurement). These measuring programs are linked to a specific measuring point. After the measurement, the relevant measurement protocols are saved under the measuring program.

There are the probes and sensors connected to the Testo 480:

- The temp/RH probe.- The wind velocity probe.- The mean radiation sensor.- The 3-function probe for testo 400 only (temp/RH and wind velocity).

Wet and Dry Blub Thermometer

Dry Bulb Temperature of Air (DBT

The temperature of the air measured by the ordinary thermometer is called as the dry bulb temperature of air, commonly referred as DBT. When ordinary thermometer is exposed to the atmosphere, it indicates the dry bulb temperature, which is nothing but the atmospheric temperature.

Wet Bulb Temperature of Air (WBT):

The wet bulb temperature of air is also measured by the ordinary thermometer, but the only difference is that the bulb of the thermometer is covered by the wet cloth. Temperature of the ordinary air measured by the thermometer when it is covered by wet cloth or wick is called as the wet bulb temperature, commonly referred to as WBT. When the air comes in contact with the wet cloth it absorbs some moisture and gives up some heat, sue to which the temperature of the air reduces. This reduced temperature measured by the thermometer is called as the wet bulb temperature.
