Independent Combustible Gas Detector

Measuring Range of 0～100% LEL combustible gas leakage alarm.
This detector can be wall-mounted and cabled easily (AC 220V-plug, DC 12V solenoid valve-plug). It is stable and don't need commission, with wide range ofenvironmental
adoption.
JT-TC521 independent detector is widely used in houses, hotels, apartments or other places that combustible gas may exist. This detector can monitor natural gas, liquefied petroleum gas and artificial gas.
Features
● Equip with high-quality gas sensor, reliable and corresponding.
● The intelligent algorithm of the microprocessors can compensate for the drift of gas sensor.
● The precision temperature sensor is a supplement of the monitoring of the environment temperature, which completely eliminates false alarms.
● LEDs indicate the detector status of normal, alarm and fault.
● The shell of the detector use fire-resistant ABS engineering plastic, clean and generous.
