Type: In-situ Laser Process Gas Analyzer

Model No.:GasTDL-3100

Introduction
In-situ laser process gas analyzer GasTDL-3100 is a high-performance laser gas analyzer based on tunable diode laser absorption spectroscopy technology (TDLAS).
With a cross-stack design, GasTDL-3100 can be used for industrial process gas control; The response time is fast, which is generally calculated in seconds in in-situ measurement. It can avoid the time delay caused by sampling measurement. The gas component concentration can be reflected online and in real time.

Features
• Adopts TDLAS technology, no cross-interference from other gas
 In-situ installation, no need for sampling or pretreatment system
 Fast response time(T90≤4s), can reflect the gas concentration in real time
 Real-time online measurement, the gas concentration is not easy to be distorted, and the measurement accuracy is high
 Good adaptability in  harsh  measurement environments such as high temperature, high dust, high moisture, high corrosion, high flow rate, etc.
 Explosion-proof design, high safety factor
 Simple structure, no consumables or moving parts, maintenance-free
