Z900 Hydrogen Sulfide Detector Product Introduction (English)
The Z900 is a portable handheld gas detector utilizing electrochemical sensor technology, capable of accurately measuring hydrogen sulfide concentrations in air from 0-50ppm with 0.1ppm resolution. Featuring an LCD display that updates readings every 10 seconds, it provides real-time monitoring of instantaneous values, peak levels, 15-minute STEL and 8-hour TWA averages. The unit incorporates an adjustable audible alarm (up to 80dB) within the detection range and low battery indication. Its ergonomic design (120×63.5×38mm, 170g) ensures field portability, powered by a standard 9V alkaline battery with 240-hour continuous operation. Optional data logging function stores complete measurement records of 5 sessions including timestamps, which can be downloaded via RS-232 interface. The sensor demonstrates 30-second response time and operates reliably within -20~50℃ temperature range. The four-electrode electrochemical cell employs active compensation technology for enhanced selectivity, with sensor output linearly corresponding to H2S concentration. 3102327
