1、 Product Usage:

Portable sulfide testermainly usedDomestic or industrial water for large, medium, and small water plants and industrial and mining enterprisesIn the watersulfideTesting, our technical personnel have discovered through extensive research that the watersulfideThe detection can be carried out by chemical colorimetry or titration. This instrument uses chemical colorimetry,Easy to operate,Easy to use, it is suitable for detecting water in various water treatment plantssulfideThe ideal instrument for various water plants to control water quality to meet the national water quality standards.

2、 Technical principle:

This instrument applies the principle of microcomputer photoelectrochemical colorimetric detection to replace the traditional titration method, eliminating the need for tedious manual operation and calculation, greatly saving manpower and time;at the same timeThe standard reagents make it easy for ordinary laboratory technicians to operate, greatly eliminating human errors, thus greatly improving measurement resolution,The numerical display of the measurement results is more accurate.
