Product Description:
Polytron TX is a microprocessor-based and cost-effective gas monitor for monitoring ammonia, hydrogen sulfide and oxygen in ambient air. Non-invasive calibration and maintenance work is carried out through the function menu selected by the monitor display window using a special magnetic rod - daily calibration does not require opening the housing (the danger level of the area environment needs to be signed before opening the lid). The Polytron TX function menu consists of only seven items, which are easy to understand and easy to use.
Product highlights
The core element of the Polytron TX 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 sensor has a built-in temperature compensation element that compensates for the temperature effect well, and the cross-sensitivity of the sensor to other gases is minimized, thus ensuring the accuracy of the sensor's measurement of the target gas.
