Product Details
KLBH - H3 Household Gas Safety Sentinel
Introduction
The Household Gas Safety Sentinel: KLBH - H3 is an essential device
for every home. Mounted on the wall, it effectively detects
combustible and toxic gases like LPG and natural gas. Equipped with
a semiconductor sensor, it samples gas through natural diffusion.
Once gas concentrations reach the preset levels—10% LEL for
combustible gas and 100 PPM for CO—it triggers visual and audible
alarms, reaching up to 70 dB. It operates on AC 220V with low power
consumption of less than 1W. We also offer OEM/ODM/R&D services
