Product Introduction
HW-HW200B is an extended-range portable infrared carbon dioxide analyzer engineered by HM Instruments for agricultural greenhouse surveillance, occupational health inspection, and enclosed industrial space safety monitoring. With an expanded measurement span from 0 to 1.000% (0 to 10,000 ppm), HW-HW200B accommodates elevated carbon dioxide levels without risking sensor over-ranging. The unit employs non-dispersive infrared (NDIR) optical technology to ensure rapid response (≤60s), excellent linearity (≤±2% F·S), and strong resistance against atmospheric moisture and ambient gases. Operators navigate an Android-driven user interface on a bright 7-inch capacitive touchscreen, accompanied by an integrated thermal receipt printer for instantaneous on-site report generation. Complete with a thermostatic heating chamber supporting low-temperature operations from -20°C to 60°C, automated zero-point calibration, and multi-period statistical averaging, HW-HW200B meets rigorous field requirements under JJG 635-2011 and GBZ/T 300.37 standards. Review detailed configurations via the HW-HW200B occupational CO2 analyzer technical profile.
