The TruePeak TDLS measures gas concentrations inside the
process, using a tunable diode laser. As the laser travels
through the process, the amount of light absorbed by the
process gas is measured to determine the gas concentration.

Designed for the most demanding applications
- O2 concentration in vapor recovery and process applications
- Combustion Gas Analysis of O2, CO, CH4, gas temperature
- Trace H2O in aggressive processes

Traditional analyzers
have to extract the sample

TruePeak
measures in-Situ

Adding cost

Reduced cost

Slowing response

Real time response

Compromising accuracy

Improved accuracy

- Unreliable and inaccurate measurements
- Problems with extracting, conditioning and
transporting the sample
- Sensor degradation
- Measurement interferences
