Product Details
Laser Methane Sensor KGD - JW - 102
Product Introduction
The laser methane sensor KGD - JW - 102 is a high-performance gas
analysis sensor independently developed by Sifang Optoelectronic.
Based on tunable laser absorption spectroscopy technology, it
adopts a high-performance probe and a gas chamber processed with
special technology. It features high accuracy, high sensitivity,
long service life, and stable performance. Using a temperature
compensation algorithm, it is not affected by the operating
environment and can work stably under harsh working conditions and
in complex gas environments. The product adopts a modular design,
which is convenient for installation. Operations such as
calibration and calibration of the product can be carried out
through the TTL communication interface. The low-power design makes
it easy for customers to maintain and integrate.
Product Features
- Measurement range: 0% - 100%LEL.
- Fast response speed, high measurement accuracy, and long service
life.
- Adopts narrow-band laser spectral absorption technology, which has
unique selectivity for methane and is not interfered by other
gases, water vapor, or dust.
- Low power consumption and modular design, easy to integrate.
