Product Details
Methane Sensor KGD - JW - 101
Product Introduction
The KGD - JW - 101 methane sensor is a four - channel methane
sensor developed based on non - dispersive infrared (NDIR)
detection technology. It can monitor the methane gas leaked in the
environment in real time. This sensor features high accuracy and
excellent long - term stability, and is widely used in fields such
as household gas alarms, portable gas detectors, natural gas
leakage detection, and gas pressure regulating cabinets.
Product Features
- NDIR technology with independent intellectual property rights.
- High selectivity for methane gas, no high - concentration
poisoning, and fast recovery time when the concentration drops from
a high - concentration environment.
- Four - channel detection technology, resistant to ethanol and
acetic acid interference, avoiding false alarms.
- High detection accuracy can be guaranteed within the full
temperature and full - scale range.
- Long service life (> 10 years).
- Small size, compact structure, and easy to install.
