Measuring each level is time consuming, but with the Harmopool check the levels are visible at every moment.
The Harmopool check can measure the following levels:
PH
Chlorine
Temperature
Flow
Level
The level is measured by a pin, which is located in the tube. When the water runs through the tube, the pin collects the data and sends it to a seperate device. This device shows the value on a small screen.
