Low-power Laser Methane Sensor KGD-GAS-204
Product Introduction
The low-power laser methane sensor KGD-GAS-204 is a
high-performance gas analysis sensor independently developed by
KACISE. Based on the tunable laser absorption spectroscopy
technology, it uses a high-performance probe and a gas chamber
processed with a special technique. It features high precision,
high sensitivity, long service life, and stable performance. By
applying a temperature compensation algorithm, it is free from
interference of the usage environment and can operate stably under
harsh working conditions and in complex gas environments. The
product adopts a modular design, making it convenient to install.
Operations such as calibration and standardization of the product
can be carried out through the TTL communication interface. With
its low-power design, it is convenient for customers to maintain
and integrate.
