4 in 1 HM100 Combo Meter Online Water Quality Tester Monitor PH Temp TDS EC Mete

4 in 1 HM100 Combo Meter Online Water Quality Tester Monitor PH Temp TDS EC Meter Water Analyzer ATC 0.0 - 60.0C for Hydroponic

HM-100 is capable of displaying the pH, EC and temperature values at the same time.

In addition, HM-100 is suitable in countinous monitoring of nutrient solution to control parameters important in plant growth, which makes it adequate equipment in hydroponics farming. Its application stretches from hydroponics to industrial and water quality areas.

pH calibration:

Prepare the 7.00pH, 4.00pH, 10.00pH standard solutions(not included).

The order of calibration is always from 7.0pH to 4.0pH to 10.0pH.

Immerse the pH and EC/TDS sensors in the standard solution for a few minutes

to stabilize the sensor readings before proceeding to calibration (EC/TDS sensor reads

the temperature)
