Product Introduction
HW-HW100A is a portable non-dispersive infrared (NDIR) carbon monoxide analyzer developed by HM Instruments for public environmental supervision, municipal sanitation monitoring, and occupational hygiene inspection. Utilizing advanced infrared optical filtering, the instrument measures low-concentration carbon monoxide in ambient air across 0 to 50 ppm with high sensitivity (0.1 ppm resolution). Its integrated electric sampling pump delivers smooth gas ingestion, monitored in real time by an onboard digital flow sensor. A 7-inch Android color touch screen provides interactive control, displaying real-time gas curves and automatically calculating 0.5-hour, 8-hour, and daily mean values. The unit incorporates dual zeroing capabilities (nitrogen zeroing and catalytic zeroing), an internal thermostatic heater for cold weather operations, and an integrated thermal voucher printer. Fully complying with JJG 635-2011 and GB/T 18204.2-2014 standards, it serves as a dependable field testing instrument.
