Residual Chlorine Meter for DPD Reagent - For Aquariums, Home Pools, Water Purifiers, Hot Springs, and Chlorine Management

Residual Chlorine Meter (DPD Method)
Manufactured by Zao Sangyo

This device measures the chlorine concentration in hot springs, swimming pools, water purifiers, and tap water.
It can be used for maintaining chlorine concentration and checking the replacement timing of water purifier filters.

I kept this as a spare, but I am listing it because I have no opportunity to use it.

This is a kit for measuring residual chlorine concentration.
Collect water in the test tube, add the included reagent.
It will turn pink when it reacts with chlorine.
The value is determined by the intensity of the pink color.

Unlike automatic measuring devices, it has fewer small parts and is less likely to break.

The measurement range is up to 2.0 mg/L, so it is sufficient for measuring general (recommended) concentrations.

It seems to be mainly used for regular measurement inspections at hot spring facilities and swimming pools.
By regularly measuring residual chlorine concentration, you can quickly detect over- or under-dosing of chlorine, making it effective for Legionella prevention.

In addition, it is also useful for hygiene management of simple home pools and for households with home water purifiers to check if chlorine is being removed.

The included accessories include reagents for measurement, so you can use it immediately.
