YESAIR offers more features, flexibility and functionality than any other IAQ instrument on the market today with multi-channel operation, more than 30 different plug and play sensors to select from, including a particulate sensor, huge capacity data logging to SD flash card and much more.
Featuring an eight channel sensor capacity including RH and temperature, YESAIR can handle up to five additional internal plug & play sensors consisting of a maximum of three electrochemical toxic gas or oxygen sensors plus two high current draw sensors such as an infrared PID or catalytic, and a remote particulate sensor such as the YESDUST.
Positive sampling with internal pump ensures good representative samples are taken from all target areas or with diffusion for a quick, direct reading. Eight sensors are viewed live on the multi-line, backlit, LCD display as well as battery and data logging status.
The optional YES Logger package consists of a 2 GB SD flash card, USB cable, YES Viewer software, and SD flash card reader. The SD flash card reader stores the data and can be transferred. Alternatively, data could be downloaded through the instrument using a standard USB connection. The YES Viewer PC software will allow users to analyze and graph data.
