Indoor Air Quality Monitor has 8-channel sensor capacity.

Press Release Summary:

Equipped with fixed temperature and RH sensor as standard, CE-certified YESAIR can handle up to 5 additional internal plug-and-play sensors: 3 electrochemical toxic gas or oxygen sensors; 2 high-current draw sensors, such as IR PID or catalytic; and remote particulate sensor. Three tactile push buttons facilitate operation, while relative humidity (RH) and temperature sensor shroud protects sensors from everyday use and promotes accelerated response to changes in RH and temperature.

CETCI Enhances Top Selling YESAIR Indoor Air Quality Monitor

Delta, B.C. - Critical Environment Technologies Canada Inc. (CETCI) has continued to enhance its top selling YESAIR indoor air quality monitor by introducing a new relative humidity (RH) and temperature sensor shroud.

YESAIR is a CE certified air quality monitor with an eight channel sensor capacity. It contains a fixed temperature and RH sensor and 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. With more than thirty sensors to choose from and only three tactile push buttons, YESAIR has high functional capabilities yet is simple to use.

With the incorporation of the new RH and temperature sensor shroud, the sensors are protected from everyday ruggedness and responds quicker to changes in RH and temperature. The old sinter was made of high density porous polyethylene causing it to be brittle and sensing process to be delayed. The new shroud is flexible and resilient to forces of pull, push, twists, and flex. It absorbs immediate contact and prevents the sensors from encountering any sharp bends. The twisted design of the shroud exposes the sensors to direct air allowing for a more rapid response.

With ongoing product development, CETCI will continue to ensure their instruments to be leading edge.
