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.
