The KDWS-28A precision mirror dew point instrument (hereinafter referred to as the instrument) is a high-precision instrument specially designed for the measurement of moisture content in industrial gases, especially for the rapid measurement of low temperature dew point. The instrument can automatically and continuously measure, with good repeatability, high sensitivity and accuracy, short measurement cycle, easy operation, intuitive reading, light weight, small size and other significant advantages.
High precision measurement: The sensor technology and algorithm used to ensure the accuracy and reliability of the measurement results.
Fast response: The measurement speed is fast, and the dew point measurement can be completed in a short time, improving the work efficiency.
Good repeatability: the results of multiple measurements are consistent, reducing errors and improving data reliability.
Easy operation: user-friendly, simple and intuitive operation, reduce the difficulty of operation.
Strong portability: light weight, small size, easy to carry and field use.

Product characteristics
The dew-point meter uses a special micro-refrigerator as a cold source, which can be quickly cooled to below -80 ° C at +40 ° C ambient temperature, avoiding the problem that similar products are difficult to cool down in high temperature environment and affect the use of.
 
The dew point meter is equipped with 7-inch LCD true color touch screen, the measurement results are automatically saved, the human-computer interaction interface is intuitive, the historical measurement results can be directly queried, the measurement data can be saved through the USB interface, the instrument gas interface adopts the quick plug interface, the connection is simple.

Main function
The main functions of the dew point meter are as follows:
a) Can automatically and quickly measure the temperature value of the dew point of water in industrial gases;
b) With continuous measurement function, the dew point meter automatically carries out cooling, detection, heating and then cooling, heating and other processes at the measurement state, and circulatory measurement; With mirror temperature cleaning function;
c) With the mirror temperature cleaning function, after stopping the measurement, if there is still dew or frost on the mirror, you can use the temperature cleaning function to eliminate the mirror dew, when reaching a certain temperature, you can automatically stop heating;
d) It has the function of automatically saving the measurement results and exporting the U disk, and can query the historical records;
e) Equipped with large screen touch display, easy to operate, intuitive reading;
f) With printing function;
