H2 3E 4% 4% Three Electrode Electrochemical Hydrogen Gas Sensor for New Energy Industry Industrial Safety Monitoring

Product Features:

Professional Full LEL Hydrogen Detection: Designed for 0–4% vol full-scale hydrogen monitoring, covering the full lower explosive limit range of hydrogen gas, meeting industrial safety detection and risk early warning standards.
Excellent Anti-Interference & Anti-Poison Performance: Optimized electrode formula effectively resists common gas interference including CO, NO2, CH4, NH3 and CO2, with strong anti-poison capability and stable anti-cross-sensitivity performance.
Zero Bias Operation & Low Drift: 0mV bias potential design, ultra-low zero current (<±100nA@20°C), low long-term sensitivity drift (<10% per 6 months), ensuring long-term stable measurement accuracy.
Humidity Insensitive Design: Unique structural optimization eliminates humidity impact on detection results, maintaining consistent output accuracy in variable humid environments (15–95% non-condensing RH).
Fast Response & High Resolution: T90 response time ≤60s, ultra-high resolution up to 100ppm, capable of capturing tiny hydrogen leakage changes in real time for rapid alarm response.
Long Service Life & High Reliability: Industrial-grade sealed structure, expected service life up to 24 months, with 18-month official warranty, suitable for long-term continuous online monitoring scenarios.
Good Batch Compatibility & Easy Integration: Standard sensor size and stable batch consistency, compatible with fixed gas detectors and portable safety monitoring instruments, convenient for equipment assembly and secondary development.

Product Applications:

New Energy Industry: Fuel cell equipment hydrogen leakage monitoring, hydrogen energy storage station safety detection, hydrogen production and purification plant gas monitoring systems.
Industrial Safety Monitoring: Chemical plant hydrogen pipeline leakage detection, industrial workshop flammable gas safety monitoring, confined space hydrogen concentration early warning.
Gas Detection Equipment: Fixed industrial hydrogen alarm systems, portable flammable gas detectors, LEL safety monitoring and calibration equipment.
Energy & Power Field: Power station hydrogen cooling system monitoring, new energy equipment hydrogen leakage protection, industrial energy consumption safety detection terminals.
