Product Introduction

HW-HW100B is an extended-span portable non-dispersive infrared (NDIR) carbon monoxide analyzer engineered by HM Instruments for industrial hygiene audits, factory occupational exposure evaluations, and hazardous workplace monitoring. With an extended measuring span of 0 to 200 ppm and a fine 0.1 ppm resolution, HW-HW100B handles higher-concentration industrial environments where conventional ambient monitors saturate. The system features a built-in diaphragm suction pump with real-time digital flow tracking between 0.5 and 2.0 L/min. Operated via an intuitive Android platform on a 7-inch color capacitive touchscreen, it computes continuous 0.5-hour, 8-hour TWA, and daily exposure averages. Equipped with dual zero-point calibration (pure nitrogen and catalytic zeroing), internal thermostatic optical chamber heating, and an onboard thermal printer, HW-HW100B ensures dependable compliance with JJG 635-2011 and GBZ/T 300.37-2017 standards. Review industrial equipment details via the HW-HW100B wide-range NDIR CO analyzer technical specifications.
