working principle
Working principle of hardness monitor TP102
The hardness monitor is an online water quality monitor. The water hardness analyzer controls the selectable limit value based on the titration colorimetric principle, provides accurate measurement value readings through the extinction method, and multiple functions ensure the reliability of real-time operation.
Low maintenance and low reagent consumption, long-term continuous operation, basically maintenance-free, especially suitable for the detection and control of water hardness of softened water such as circulating cooling water and boiler water, and can be used with our multi-channel distributor to easily achieve 2-8 channels of automatic measurement without stopping.

Precautions
1. When the hardness tester has obvious faults, users should not open it to repair it by themselves, please contact the manufacturer in time.
2. If there is no display after turning on the machine, please check whether the power cord is connected properly.
