Vaisala’s GMW90 the ultimate tool for HVAC professionals
January 2014Analytical Instrumentation & Environmental Monitoring
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.
Microglow technology
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 the sensors 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 carbon dioxide instruments. Replacing the incandescent light bulb has significantly improved sensor stability, moreover, the sensor’s operational life has extended by 50%. Through intelligent optical design fewer components are required, which helps to increase the overall reliability of the sensor. The GMW90 includes a sliding cover that allows for faster calibration and service. Most importantly, the compliance and traceability of the measurements are never compromised.
Vaisala’s reliable technology and state-of-the-art design brings an efficient and robust carbon dioxide measurement device to the market.
