A Low Cost Portable IAQ Solution

Critical Environment Technologies Canada Inc. to introduce YESAIR Junior at the AIH Conference & Expo in Denver, Colorado

Delta BC, CANADA ??? YESAIR Junior is a new low cost, light weight hand held device. It contains three key sensors that are aimed to simultaneously measure and record temperature, relative humidity, and carbon dioxide levels in the air.

The LCD display indicates all three sensors and measured values for each as well as battery status.

This essential device collects up to 22,000 data points and stores it in the internal flash memory.

Users have the option of extracting the data through a USB port for analysis with our optional YES Viewer pc software.

The device utilizes alkaline batteries, providing more than twenty hours of run time, or a supplied wall adapter, providing continuous operation.

The new YESAIR Junior is ideal for Indoor Air Quality (IAQ) applications and will be available in early fall 2010. Every YES product is designed to deliver years of reliable operation and is easy to operate.
