Critical Environment Technologies Canada Inc. (CETCI) will launch their new and improved YES Plus LGA at this year’s American Industrial Hygiene Conference and Expo in Denver, Colorado.

YES Plus LGA has enhanced, easy to use features that will replace the current YES Plus monitor. This single-solution system is a multi-gas air quality monitoring and information recording instrument that simultaneously measures and records temperature, relative humidity, carbon dioxide, and much more.

Featuring a fifteen sensor capacity, the YES Plus LGA allows users to accurately monitor more within a single, easy to carry instrument. It contains twelve internal plug & play sensors, a fixed temperature sensor, a removable relative humidity (RH) sensor, and a remote sensor, such as particulates. Sensors available include electrochemical, catalytic (combustibles % LEL or % volume), infrared (PPM or % volume CO2 or combustibles), and PID. An air sample from the target environment is delivered to the sensors through 'active sampling' by the internal sample draw pump. More than a million data points can be logged and stored in a built-in SD flash card for convenience.

The large, backlit, multi-line scrolling LCD display indicates the sensor types installed and measured values for each gas, battery status and more. The system utilizes a long life rechargeable NiMH battery pack providing more than twenty hours of run time, depending on sensor array installed. The user can also set one alarm level for each gas to activate the internal audible alarm. The system is housed in a rugged ABS enclosure with swivel handle to act as a stand support or for carrying the instrument.

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 in the fall of 2010.

The new YES Plus LGA is ideal for Indoor Air Quality (IAQ) applications and Landfill Surface Gas Emission applications. Every YES product is designed to deliver years of reliable operation and is easy to operate.
