JT-HR100

A household gas alarm is a safety device designed for residential environments to continuously monitor the presence of combustible or toxic gases, such as natural gas (methane), LPG, or carbon monoxide (CO).

When the gas concentration exceeds the preset alarm threshold, the alarm activates audible and visual alerts to warn occupants and help prevent fires, explosions, or poisoning incidents caused by gas leaks.

JT-HR100 Household Combustible Gas Alarm

Intelligent gas safety protection solution


Product introduction

JT-HR100 Household Combustible Gas Alarm is a safety monitoring device specially designed for home and indoor environment. The product can continuously detect the change of combustible gas concentration in the air and give early warning in case of gas leakage.

The equipment adopts high-sensitivity gas sensing technology, which can quickly detect the abnormal change of combustible gas concentration. When the detected gas concentration reaches the preset alarm value, the alarm will automatically start the acousto-optic alarm function to remind users to take emergency measures in time.

Flammable gas leakage is one of the main safety hazards in residential and indoor environment. Because the leaked gas is usually not found by human senses in time, installing a reliable gas alarm can effectively improve the safety protection ability and reduce the risk of fire and explosion caused by gas leakage.

JT-HR100 is suitable for all kinds of indoor places using gas equipment, including homes, apartments, kitchens, hotels, restaurants, offices and other commercial environments.


What is a household combustible gas alarm?

Household combustible gas alarm is a kind of safety monitoring equipment for continuously detecting the change of combustible gas concentration in indoor air.

When the detected gas concentration exceeds the preset alarm threshold, the equipment will automatically start an audible and visual alarm to remind personnel to take safety measures such as closing the gas valve, ventilation and evacuation in time.

Common sources of combustible gas leakage include:

  • Natural gas pipeline
  • Liquefied petroleum gas (LPG)
  • gas stoves
  • gas heater
  • Gas heating equipment
  • boiler
  • Other combustion equipment

JT-HR100 can continuously monitor indoor gas environment, and help users find potential leakage risks in advance through real-time detection and rapid alarm mechanism.


Working principle of JT-HR100

JT-HR100 adopts high-performance gas sensing technology, and realizes fast and accurate gas leakage monitoring by detecting the change of combustible gas concentration in the surrounding environment.

The equipment converts the gas concentration change into an electrical signal through a sensor, and carries out data analysis and processing through an internal control circuit.

Detection process

The complete monitoring process includes:

  • Indoor air enters the gas detection area through the air inlet;
  • Combustible gas molecules contact the sensor;
  • The sensor detects the change of gas concentration;
  • The sensor converts the change of gas concentration into an electrical signal;
  • The internal circuit processes and analyzes the detection data;
  • The system compare that detected concentration with a preset alarm value;
  • When the gas concentration exceeds the safety threshold, the equipment automatically starts the alarm;
  • Buzzer and LED indicator light send out warning signals.

The whole detection process can run automatically without manual operation, providing continuous protection for indoor gas safety.
