According to http://www.flir.com/ogi/,
FLIR received third-party validation of the FLIR GFx320, GF320, GF300, and G300a cameras' compliance with the following sensitivity standard laid out by the EPA in the NSPS OOOOa methane rule: Your optical gas imaging equipment must be capable of imaging a gas that is half methane, half propane at a concentration of 10,000 ppm at a flow rate of ≤60g/hr from a quarter inch diameter orifice.
They have a certificate and webinar training course posted on the above site. Their cameras can detect:
- METHANE (CH4) / NATURAL GAS
- AMMONIA (NH3)
- BENZENE (C6H6)
- CARBON MONOXIDE (CO)
- ETHYL ALCOHOL (C2H5OH)
- HYDROCARBONS / OLEFINS
- HYDROGEN (H2) / CARBON DIOXIDE (CO2)
- PROPANE (C3H8) / BUTANE (C4H10)
- PROPYLENE (C3H6)
- REFRIGERANTS / R-134A (CH2FCF3)
- SULFUR HEXAFLUORIDE (SF6)
- TRICHLOROETHYLENE (C2HCL3)
- VINYL CHLORIDE MONOMER (C2H3CL)
For the infrared cameras, it looks like some of the cameras detects some of the chemicals listed below with this note:
"Gases Detected and Minimum Detected leak rate (MDLR) Independent laboratory (third party) testing confirms that the GasFindIR cameras can see the following gases at the minimum detected leak rate (MDLR):
1-Pentene - 5.6g/hr Benzene - 3.5g/hr Butane -0.4g/hr Ethane - 0.6g/hr Ethanol - 0.7g/hr Ethylbenzene - 1.5g/hr Ethylene - 4.4g/hr Heptane - 1.8g/hr Hexane - 1.7g/hr Isoprene - 8.1g/hr MEK - 3.5g/hr Methane - 0.8g/hr Methanol - 3.8g/hr MIBK - 2.1g/hr Octane - 1.2g/hr Pentane - 3.0g/hr Propane - 0.4g/hr Propylene - 2.9g/hr Toluene - 3.8g/hr Xylene - 1.9g/hr"
