Product Details
Laser Oxygen Sensor KGD - GAS - 401
Product Introduction
The Laser Oxygen Sensor KGD - GAS - 401 is a high - performance gas
analysis sensor independently developed by KACISE. Based on Tunable
Diode Laser Absorption Spectroscopy (TDLAS) technology, it uses a
high - performance probe and a gas chamber processed with special
techniques. It features high accuracy, high sensitivity, long
service life, and stable performance. With a temperature
compensation algorithm, it is unaffected by the operating
environment and can operate stably under harsh working conditions
and in complex gas environments. The product adopts a modular
design for easy installation. It can be calibrated and calibrated
through the TTL communication interface. The low - power -
consumption design facilitates customer maintenance and
integration.
Product Features
- Adopts narrow - band laser spectroscopy absorption technology,
which has unique selectivity for oxygen and is unaffected by other
gases, water vapor, and dust.
- Fast response speed, high measurement accuracy, and long service
life.
- Low - power - consumption, modular design for easy integration.
- Unaffected by vibration and electromagnetic influence.
