Product Details
Laser Oxygen Sensor KGD - GAS - 402 for Anesthesia Machines
Product Introduction
The Laser Oxygen Sensor KGD - GAS - 402 is an oxygen sensor
designed based on the principle of Tunable Diode Laser Absorption
Spectroscopy (TDLAS). It can quickly, in real - time, and
accurately measure oxygen concentration. It is applied in medical
equipment such as cardiopulmonary exercise instruments, anesthesia
machines, and ventilators. It can replace paramagnetic oxygen
sensors and has the advantages of fast response speed, long service
life, and being unaffected by vibrations and environmental factors.
Product Features
- Adopts TDLAS technology with a detection accuracy of up to 0.3%FS
- Fast response in 170ms (T90)
- Maintenance - free, no consumables, with a service life of over 10
years
- Unaffected by vibrations and environmental factors
- Good compatibility, capable of simultaneously measuring CO₂
concentration
