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.
