GasBadge Pro (H₂) is a portable, intrinsically safe hydrogen (H₂) single gas detector designed by Industrial Scientific, USA. It is engineered for harsh environments such as coal mines, metallurgy and chemical plants, providing real-time monitoring of hydrogen concentration to prevent explosion hazards.
Product Advantage
1. Certified Safety: With MA certification and intrinsic safety design, ideal for underground coal mines to prevent hydrogen explosion.
2. Accurate Detection: Original electrochemical sensor, range 0–2000ppm, pre-calibrated, stable and anti-interference.
3. Long Runtime: Powered by CR2 lithium battery for around 1-year continuous use, only annual calibration needed.
4. Light & Rugged: Weighs 85g for easy wearing. IP65 rated, shockproof and RFI-resistant for harsh mine conditions.
5. Triple Alarm: Audible, LED and vibration alarms with adjustable thresholds for reliable warning.
6. Data Traceability: Large data storage for STEL/TWA and alarm records, supporting infrared download.
7. Easy Operation: Backlit display and simple keys, operable with gloves. Infrared calibration without opening housing.
8. Warranty: Comes with official lifetime warranty.
