HM Digital PH-200 Waterproof Tester 2 years warranty
This is the HM Digital PH-200 Waterproof Tester, essential for hydroponic cultivation and useful for growing on soil.
Designed in the United States, the HM Digital PH-200 Waterproof measures the pH values (Hydrogen Potential) of a nutrient solution and guarantees an accuracy to the nearest hundredth (+/-0.01).
The HM Digital PH-200 Waterproof allows to closely follow the pH values given to the plants and thus toensure a better assimilation of the nutrients by the root system.
In addition, the HM Digital PH-200 Waterproof is practical and reliable. But clumsy growers will also appreciate the fact that this top-of-the-range tester meets IP 67 standards (submersible and floating objects) and remains waterproof only if the clamping ring and the cover are screwed on correctly!
In addition, the HM Digital PH-200 Waterproof tester offers an automatic calibration, making monthly calibrations very simple and fast as this operation is based on a simple press of the appropriate push button. And that's it!
Finally, the HM Digital PH-200 Waterproof integrates the ""Hold"" function (maintains the measured pH value), theindication of nutrient solutiontemperatures and the possibility of changing its HM Digital probe, available as an option.
Instructions for use:
- turn on the switch of the HM Digital PH-200 Waterproof, remove the protective cap and immerse the probe end of the tester;
- do not forget to turn itoff and rinse it with clean water after each use;

- regularly check the clamping ring and the cover of the HM Digital PH-200 Waterproof to ensure that it is watertight;
- remember to recalibrate monthly with a suitable calibration solution, known as "buffers" with a pH value of 4.0 or 7.0.
