Product Details

Online explosion-proof oxygen transmitter has a liquid-crystal display that makes the display visual and the operation easy.The set of the menu can be accomplished by magnetic pen under explosion-proof occasion which is convenient for the operation in the scene.
Online explosion-proof oxygen transmitter main features:
1.The imported micro-fuel cell oxygen sensor has the advantages like a rapid response speed, high measured accuracy, excellent linearity, long calibration period, weak-acid resistance and weak-alkali resistance;
2.Only one random point needs to be calibrated among the whole measurement range, making the calibration operation simple and convenient;
3.The auto-compensation system for pressure with high accuracy could eliminate the influence from environment pressure;
4.The auto-compensation system for temperature with high accuracy could eliminate the influence from environment temperature.
