The tester will help determine the level of water hardness in a water supply system, well, lake, or aquarium.

for fish, etc.

Characteristics:

- Compact size of the device;

1. Remove the device from the case.

2. Remove the protective cover from the water hardness meter.

3. Press the On/Off button once before putting the device into the water. “000” will appear on the device display.

4. Immerse the device in water approximately 3.5 cm.

5. Wait until the display readings stabilize. The device automatically makes temperature compensation. Once the readings stabilize (10-30 seconds), press the HOLD button. The last button is responsible for fixing measurement indicators on the display. Remove the device from the water and evaluate the measurement readings.

7. Do not forget to wipe the device with a soft cloth after use.

Useful information: Ratios of some units of water hardness: 1 mEq/l=50.05 ppm CaCO3, 1 f=10 ppm, 1 µS=2.19 ppm, 1 dH=17.8 ppm.
