Product Details
Household Infrared Combustible Gas Detector KGD-JT-202
Product Introduction
The Household Infrared Combustible Gas Detector KGD-JT-202 applies
the NDIR (Non-Dispersive Infrared) spectral analysis technology,
which can accurately measure methane (CH4) gas. When the natural
gas leakage reaches the alarm concentration, the detector can send
out audible and visual alarm signals. The product has a long
service life and requires no maintenance, effectively reducing the
usage cost for customers. Moreover, it features high precision and
strong anti-interference ability, and is especially suitable for
the complex environment of Chinese-style kitchens, ensuring no
false alarms or missed alarms.
