Point Type Combustible Gas Detector

The GT-FGA1000L combustible gas detector adopts the world's leading non-dispersive infrared absorption principle, with advantages such as long lifespan, wide measurement range, no dependence on oxygen, and no poisoning failure. This product can monitor the concentration of combustible gases in various harsh conditions, and is widely used in various occasions where flammable and explosive gases exist, such as petroleum, chemical, oil fields, oil depots, liquefied gas stations, etc.

Features

1. Adopting industrial-grade 32-bit PIC microprocessor, it has very high calculation and data processing speed.

2. Infrared sensor - higher sensitivity and long-term stability.

3. With high brightness LED Nixie tube display, the remote reading can be clearly recognized.

4. IR remote control, do not need to open the case for on-site operation.

5. Integrated sound and light alarm: sound ≥85dBA and 500ucd LED light brightness.

6. Intelligent self-test function.
