Vaisala release the ultimate tool
The GMW90 is the ultimate tool for HVAC professionals looking for an easy to use, hassle-free solution to carbon dioxide measurements. Customer feedback played a vital role in developing the GMW90, a high quality measurement sensor which offers ease of use, compliance with standards, extended lifetime and minimal maintenance, all of which provide peace of mind.
GMW90 is the first sensor to feature the new generation of CARBOCAP sensors with microglow technology. Microglow is a Vaisala-patented silicon MEMS emitter infrared source. This unique low power, silicon-based infrared source is built in-house at Vaisala. Using this technology, the performance of CARBOCAP sensors has been even further improved. It represents next generation infrared technology that solves many of the challenges that impact traditional infrared sources. Low power consumption enables correct RH+T measurements in CO2 instruments.
Replacing the incandescent light bulb sensor, stability has significantly improved. Moreover, the sensors operational life has extended by 50%. Through simplified design and intelligent optical design fewer components are required, which help to increase overall reliability of the sensor. The GMW90 includes a sliding cover, which allows for faster calibration/service.
