Portable dual case design, small size (without condenser)

Measuring optical path length at 10m for more accurate measurement

Continuous and extractive measurement of up to 11 gas components

No instrument gas required

Ultra long running time, high reliability

Independent operating software, highly user-friendly interface

The measurement principle of gas components is based on the specific infrared light absorption characteristics of different substances. Infrared light directly passes through the measuring gas, and as the substance absorbs a specific wavelength, the light intensity decreases, reflecting changes in concentration.

The testo 370 uses three different measurement methods for calculating gas concentration:

Dual wavelength measurement method

Gas related filtration

Oxygen measurement
