Polytron TXoxygen Detector

Specifications

Product Description:

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.

Product highlights

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. Transmitter installation is simple and easy: just fix the transmitter to the wall, install the sensor, and connect the transmitter with a 24-volt DC power supply via a steel pipe with a two-core cable. The sensor is calibrated before leaving the factory and does not need to be recalibrated during commissioning.
