Specifications

LCD screen,Touch keyboard.

Custom curve calibration function.

Automatic multi-point correction.

The instrument uses photoelectron colorimetric detection principle instead of the traditional visual colorimetry. Human error is eliminated, so the measurement resolution is greatly improved. During the measurement, the water sample will rapidly develop color when the test sample is put into a specific reagent. Then put the water sample into the photoelectric colorimetric seat. The instrument will compare the color depth to get the ion concentration value.
The instrument can be applied to the detection of ion concentration in the domestic or industrial water of large, medium and small water plants, industrial and mining enterprises, swimming pools and other places so as to control the water parameters to meet the required water quality standards.
