Methane Detectors Challenge for EDF
The gas sensing technologies performed well in detecting methane concentrations over a range of temperature and humidity conditions.
Four technologies were selected by EDF • Dalian Actech/SenSevere • SenseAir AB • Quanta3 • University of Colorado/NDP Group
The remaining companies are advancing to second phase field testing, in San Antonio Texas, throughout spring and summer 2015, providing more intensive indoor and outdoor testing and evaluation.

Paul Smith, STSM fellow from Cambridge at SenseAir:
“Investigation of SenseAir LPL (Long Path Length) platform iBASS for precise gas measurements” Scientific report COST-STSM-TD1105-24560
My research project at Cambridge University, is to integrate this sensor into a package suitable for use with weather balloons. The sensor therefore, needs to be able to withstand extremes of temperature and pressure, be cheap, and low power. I am working in partnership with SenseAir to find solutions to these problems.

Together SenseAir & In Situ were in Oct 2014 announced as one of three winners in the competition Boost Innovation™ for a new measuring system with sensor technologies to measure terrestrial greenhouse gas.
“An innovative collaboration that takes a known measurement technology to a new level”

In Situ has been involved in almost all major greenhouse gas projects in Sweden during the last 15 years. They have supplied equipment for measuring greenhouse gases in the atmosphere to countries including Iceland, Czech Republic, South Africa, Russia and Germany.
In Situ has designed, built and installed the Swedish part of ICOS (Integrated Carbon Observation System), a new infrastructure for research on greenhouse gases
Also, they have worked with greenhouse gas measurements under water on behalf of Uppsala University

The new SenseAir HPP, High Performance Platform, has proven that it is suitable for greenhouse gas measurements in various demanding environments:
• Low gas concentrations
• Large temp variations
• Humidity
• Corrosive / polluted air
HPP will be produced at a reasonable cost
A fully equipped sensor unit can automatically recalibrate itself
