Specifications
SKU: ERANNTEX Diffusion-Type Hydrogen Tester
The Diffusion-Type Hydrogen Tester is a portable detection device from Eranntex, designed for hydrogen detection across multiple scenarios including petroleum, chemical, and coal mining. It can also be customized to simultaneously detect 1-4 other gases as needed. Equipped with a high-precision hydrogen sensor, it achieves detection accuracy ≤±3% FS and resolution as low as 0.001ppm. With a T90 response time ≤20 seconds and automatic zero tracking to prevent drift-induced data errors, it delivers reliable performance. The unit features an IP65-rated housing with intrinsically safe circuit design for explosion-proof and shock-resistant performance. Its LCD screen clearly displays gas concentration and other critical information. Supporting multiple alarm modes including audible, visual, and vibration alerts, it serves as a reliable tool for hydrogen safety detection.
Advantages of the Diffusion-Type Hydrogen Tester:
High Precision & Fast Response: Equipped with a high-precision hydrogen-specific sensor, it achieves detection accuracy ≤±3% FS and resolution as high as 0.001ppm. With a T90 response time ≤20 seconds and automatic zero tracking technology, it effectively prevents drift, ensuring precise and error-free data.
Multi-scenario Durability: High protection rating + intrinsically safe explosion-proof circuit design ensures dustproof, waterproof, and vibration-resistant performance. Suitable for complex and harsh environments like petroleum, chemical plants, and coal mines, withstanding high-temperature and high-humidity conditions.
Multi-gas Flexibility: This diffusion-type hydrogen detector supports optional detection of 1-4 additional gases, meeting multi-gas monitoring needs. One device handles multiple gases, reducing procurement costs.
Water-splash, dust-proof, explosion-proof, shock-resistant. Intrinsically safe circuit design with anti-static and anti-EMI capabilities. Passed national standard testing and CMC metrological instrument production license certification.
Protection Rating: IP65
