Features:
1. Segment code screen display, intuitive display, simple and convenient operation; 2. The original imported thermal conductivity sensor has the characteristics of high test accuracy, long calibration interval and long service life; 3. Menu lock function to prevent misoperation from changing instrument parameters and affecting its performance; 4. In explosion-proof occasions, the menu setting can be completed through an isolated magnetic pen, which is convenient for on-site operation; 5. When the power is turned off, the service life of the sensor will not be lost; 6. Automatic temperature compensation function to eliminate the influence of temperature change on the measured value; 7. The meter supports multi-point segmented linear calibration, which can meet the accurate measurement of concentration in the full range; 8. The airway of the test cavity is specially designed, and the polymer film is embedded to effectively prevent the influence of liquid and interfering medium on the sensor. |
Application:
| The explosion-proof grade is required to measure hydrogen content in ammonia decomposition and protective atmosphere equipment in Exd IIC T6 environment, online measurement of hydrogen content in welding and cutting proportioning gas; online monitoring of hydrogen content in hydrogenation and purification nitrogen generators. |
