Product Description

Principle

Features

Parameters

Principle:

Potassium permanganate solution and sulfuric acid solution are added to the sample, mixed and digested. Potassium permanganate oxidizes the organic pollutants in the sample and the color of the water sample changes. The monitor detects this color change and converts it into a permanganate index value and outputs it.

Features:

touch panel
Multi range, automatic switching
Level 3 operation permissions
State self diagnosis function
Abnormal or power outage data protection
Built in multiple communication protocols
Scheduled testing and automatic verification
Power off and restart, automatic emptying, cleaning, and reset
Running log records, process and operation records can be checked
remote monitoring, remote operation instructions
Timed testing, automatic verification
