VQ21TB Combustible Gas Sensor Catalytic Combustion Bridge Type Double Beads

VQ21TB Combustible Gas Sensor Catalytic Combustion Bridge Type Double Beads

Key Features

1. Poisoning Resistance: Resistant to pollutants such as silicon, sulfur, and chlorine, suitable for harsh industrial environments.

2. Dual-bead Design: Self-compensating, minimal temperature and humidity drift, high stability.

3. Broad-spectrum Detection: Uniform response to most combustible gases, suitable for general applications.

4.Low Voltage: 2V power supply, suitable for fixed-point online monitoring (not low-power portable).

Typical Applications:

Industrial combustible gas detectors (fixed point);

Urban gas pipeline/gas station leak monitoring;

Petrochemical plants, wastewater treatment plants;

Commercial kitchens, cold storage facilities (R32/R290 refrigerant leaks);

Ambient air quality monitoring equipment.
