1、 Main features

1. The electronic circuit has high integration, good reliability, simple operation, and ensures stable and reliable instrument quality. It can operate continuously for a long time, which not only ensures work efficiency but also saves maintenance costs. It automatically remembers operating parameters and does not require resetting when starting up.

2. Equipped with a gas cut-off protection system to prevent instrument damage caused by misoperation.

3. The gas path system adopts a structure that improves the stability of the instrument gas velocity, thereby obtaining well reproducible analysis results.

4. Analyzable liquefied gasdimethyl etherThe content of various components such as propane, propylene, isobutane, isobutene, and n-butane. Calculate the calorific value, density, etc. of liquefied gas through each component. Content range: 0.01%~100%.
