The core element of Dräger Polytron TXtoxic gas monitors is Dräger electrochemical sensors with the latest technology in the field of gas detection. Dräger sensors have the characteristics of high accuracy, good stability and long life. The Dräger Polytron TXtoxic gas monitor sensor has a built-in temperature compensation element that compensates for the temperature effect well and the sensor's cross-sensitivity to other gases is minimized, thus ensuring the accuracy of the sensor's measurement of the target gas.
