1、 Product Usage:

Water hardness refers to the total concentration of calcium and magnesium ions in a water sample, and it is an important indicator of water quality. The YD300A water hardness tester uses electrode method for testing, and extensive experiments have shown that it has the same accuracy as EDTA titration method. It is suitable for detecting water hardness concentration in large, medium, and small water plants, industrial and mining enterprises, domestic or industrial water, in order to control water hardness to meet the specified water quality standards.

2、 Technical indicators:
1. Measurement range: 0-500mg/L

2. Resolution: 0.1mg/L
3. Repeatability: ≤ 2%

4. Indication error:≤±5%FS
5. Power supply voltage: DC 9V

Instrument features:

Microcomputer, touch sensitive keyboard is easy to use.

The sensor adopts a hardness electrode, which consists of a measuring electrode and a reference electrode, with stable potential, fast response time, and easy use.

Equipped with B1, B2, and B3 calibration solutions for fully automatic three-point calibration, the current value is automatically locked after the reading stabilizes.

High resolution, instrument resolution reaches 0.1 mg/L.
