YESAIR Junior IAQ Monitor

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 (CO2) 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 26,000 data points and stores it in the internal flash memory. Users can download the data through a USB port for analysis with our YES Viewer pc software.

The device utilizes alkaline batteries, providing up to 24 hours of run time, or a supplied wall adapter, providing continuous operation.
