CO2Meter AZ-0001 pSense Portable CO2 Indoor Air Quality Meter, Yellow

With up to 24 hours battery life and easy to use with gloves on, the pSense portable carbon dioxide and air quality meter works perfectly as a personal safety alarm unit in hazardous environments, or wherever carbon dioxide is produced, stored, generated and used. The large LCD readout gives a quick overview of the current carbon dioxide level 0-9,999ppm, and the 80 dB audible alarm calls for prompt attention when the short-term exposure safety limit is exceeded. The meter calculates statistical weighted averages of TWA (8 hour time weighted average) and STEL (15 minute short term exposure limit). The pSense comes with a shatter-resistant ABS carrying case, 4 AA batteries, universal 110/220V power supply and manual.
