Product Description

4H2-40000 CLE-0644-400 Electrochemical Hydrogen Gas Sensor for Hydrogen Fuel Cell Systems Industrial Safety

Applications:

Hydrogen fuel cell systems: Monitoring hydrogen leakage in fuel cell vehicles and stationary power systems.
Industrial safety: Detecting H2 leaks in chemical plants, refineries, and hydrogen storage facilities.
Confined space monitoring: Ensuring safe H2 levels in enclosed work areas.
Portable gas detectors: Integration into handheld devices for on-site safety inspections.

Key Features:

High range detection: 0–40,000 ppm (0–100% LEL) for comprehensive hydrogen monitoring.
High sensitivity: 0.007 ± 0.002 μA/ppm for precise low-level detection.
Fast response: T90 response time ≤ 60 seconds for timely leak alerts.
Stable performance: Low baseline drift (0–20 ppm equivalent from -20°C to 50°C) and long-term output drift < 2% signal/month.
Standard form factor: Compatible with standard 4-series sensor sockets for easy replacement.
