Product Details
Household Combustible Gas Detector KGD-JT-201
Product Introduction
The Household Combustible Gas Detector KGD-JT-201 is a gas alarm
installed in places such as kitchens where gas (CH4) leakage may
occur. When the gas concentration in the air exceeds the set value,
the detector will trigger the alarm function and send out audible
and visual alarm signals. If the device is connected to an alarm
host and an alarm receiving center, it can realize networked alarm
and simultaneously close the gas pipeline valve. It can also be
monitored in real time through a mobile phone APP. Once the alarm
concentration is exceeded, the APP will promptly pop up the alarm
information to ensure the safety of life and property.
Product Features
- Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology with
independent intellectual property rights
- Adopting narrowband laser spectral absorption technology, it has
unique selectivity for methane and is not interfered by other
gases, water vapor, or dust.
- It can ensure high detection accuracy within the full temperature
and full measurement range.
- Fast response time
- Remote real-time monitoring via APP
- Plug-and-play for convenient operation
- Resistant to high concentrations of acetic acid and ethanol, and
will not cause false alarms.
- Fault self-checking function
- High reliability and long service life (10 years)
- Maintenance-free
- Has the functions of historical data recording and querying,
automatic recording of alarm events, automatic storage, and
automatic updating.
- Has the function of data uploading
- Small in size, compact in structure, and easy to install
