Critical Environment Technologies Canada Inc. (CETCI) is a known industry leader and innovator for the indoor air quality (IAQ) market. Their two best selling portable IAQ instruments are the YESAIR and YES Plus LGA.

Both IAQ instruments are portable, multi-channel monitors featuring thirty different internal plug and play sensors to select from and a remote particulate sensor that simultaneously monitors within a single, easy to carry instrument. CETCI’s plug & play sensor options are the widest selection on the market and include electrochemical (carbon monoxide, nitrogen dioxide, nitric oxide, ammonia, chlorine dioxide, formaldehyde, arsine, fluorine, hydrazine, phosphine, silane, and many more), catalytic (combustible gases), infrared (CO2 or combustible gases), and PID (TVOC). Users can set one alarm level for each gas to activate the internal audible alarm. Both instruments have a built-in SD flash card for data logging and an internal sample pump for “active sampling”. The LCD display, on both, indicates each sensor type installed, measured values for each gas, battery status, and more.

YESAIR has been on the market since 2006. Even today, it still offers more features, flexibility and functionality than any other instrument on the market. YESAIR is CE certified and has a seven-sensor capacity with up to five internal plug & play sensors, a fixed temperature sensor, and a fixed relative humidity (RH) sensor. The LCD displays all the installed sensors simultaneously and can operate 12-14 hours with a NiMH battery pack or continuously with a wall adapter. The instrument is enclosed in a rugged ABS/polycarbonate enclosure and can either be a handheld, stand on a flat surface, or fastened to a wall for permanent or semi-permanent use. With only three tactile push buttons makes the YESAIR simple to use. Optional features include internet and network accessible.

YES Plus LGA was recently introduced to the market earlier this year as an upgrade from the original YES Plus. This single solution, multi-sensor IAQ and landfill surface gas emissions monitor is pending CE certifications. It features four tactile push buttons for easy use and a fifteen sensor capacity with up to twelve internal plug & play sensors, a fixed temperature sensor, a RH sensor, and a remote sensor. The LCD displays up to six installed sensors at one time and scrolls to display more. It can operate 18-24 hours with a NiMH battery pack or continuously with a wall adapter. YES Plus LGA is housed in a rugged ABS enclosure and has an aluminum swivel handle that acts as a handheld or stand support.

The Landfill Gas Analyzer (LGA) version has an optional plug-in GPS and Bluetooth module and a firmware version that’s suitable for landfill surveys to communicate to pocket PDAs. The internal sample pump has an automatic flow control that ensures 1-LPM flow rate even with resistance. This version will be available later this fall.

CETCI will continue to develop and expand their portable IAQ product line to meet the needs of the market. For more information on the entire range of IAQ instruments and gas detection systems, please visit www.critical-environment.com.
