Wearable MiniMeta H2S Gas Detector With Sound Light Vibration Alarm, IP68 Waterproof
MiniMeta is an IECEx/ATEX/EMC certified single-gas detector specially designed for hydrogen sulfide (H2S) monitoring. Equipped with a high-precision electrochemical sensor, it provides a measuring range of 0–200 ppm and resolution of 0.1 ppm for accurate and stable detection. With an ultra-long battery life, IP68 waterproof/dustproof design, and triple alarm system, it provides reliable personal safety protection in harsh industrial environments.
Product Overview
MiniMeta is a compact, lightweight, and low-cost wearable single-gas detector for continuous real-time monitoring. It uses a high-stability electrochemical sensor to ensure fast response and reliable readings. The device supports automatic self-test, multi-parameter display (real-time value, TWA, STEL, MAX, MIN), and triple alarm to ensure operators can quickly identify dangers.
It features a replaceable battery and sensor, IP68 high protection grade, and up to 2 years of standby time, greatly reducing maintenance costs. It can work with the optional DKM-MiniMeta docking station for one-key bump test, calibration, data recording, and configuration management to simplify daily maintenance.
