YESAIR 8-Channel IAQ Monitor

The YESAIR 8-Channel Indoor Air Quality (IAQ) Monitor is a versatile, battery-powered, handheld instrument designed for intermittent or continuous monitoring of indoor air quality. It measures temperature, relative humidity (RH), and up to five gases, making it suitable for applications in residential and commercial buildings, hospitals, schools, airports, research facilities, and more. With over 30 plug-and-play sensor options, the YESAIR can detect a wide range of gases, including ammonia, arsine, carbon dioxide, carbon monoxide, chlorine, hydrogen sulfide, methane, ozone, TVOCs, and more.

​

The monitor is available in two models: Pump and Diffusion. Each supports multi-channel operations and includes one temperature sensor, one RH sensor, and space for five internal gas sensors. These can include up to three electrochemical toxic gas or oxygen sensors, plus two high-current draw sensors, such as infrared, PID, catalytic, or particulate sensors. Real-time sensor readings, battery level, and data logging status are displayed on a multi-line, backlit LCD screen.

​

The YESAIR offers optional data logging capabilities with a 2GB SD memory card and accompanying YES Viewer software. This allows users to collect, transfer, analyze, and graph data via USB or SD card. For enhanced monitoring, the Pump model includes an optional sampling probe with a 10" wand and 30" tubing for hard-to-reach areas.

​

Key features include a lightweight, ergonomic design, RoHS-compliant circuit boards, CE certification, and user-friendly menu navigation. It supports gas sampling through either an internal sample draw pump or diffusion and provides flexible data logging and analysis capabilities, making it a reliable tool for various indoor air quality assessments.
