ATO Portable Hydrogen (H2) Gas Detector, 0–500/1000/2000 ppm, Rechargeable H2 Leak Detector with LCD Display, Audible Visual Vibration Alarm (with Data Logging, 0-500ppm)

ATO Portable Hydrogen (H2) Gas Detector is designed for accurate and reliable hydrogen gas monitoring in daily safety and maintenance applications. Equipped with an electrochemical sensor and a built-in micro pump, it actively draws gas samples to deliver stable and responsive measurements.This portable H2 detector supports multiple measuring ranges, including 0–500 ppm, 0–1000 ppm, and 0–2000 ppm, making it suitable for hydrogen leak detection, equipment inspection, and general safety checks. The dot-matrix LCD provides real-time readings of gas concentration, units, and operating status, while audible, visual, and vibration alarms enhance user awareness in noisy or low-visibility environments.Model: GD200-H2Sampling Method: Pump type, flow rate can be up to 750ml/minDetection Principle: ElectrochemistryRange (Optional)*: 0 to 10 ppm, 0 to 20ppm, 0 to 100ppm, 0 to 500ppm, 0 to 1000ppm, 0 to 2000ppm, 0 to 3000ppm, 0 to 5000ppm, 0 to 10000ppm, 0 to 20000ppm, 0 to 40000ppm, 0 to 4% VOLResolution: 0.001ppm (0-10/20ppm), 0.01ppm (0-100ppm), 0.1ppm (0-500ppm), 1ppm (0-1000/2000/5000/10000/20000/40000ppm) or 0.001% VOL (0-4% VOL)Accuracy: ≤±3% F.S.Certification: CE, ATEX (Standard: EN IEC 60079-0:2018, EN 60079-1:2014)
