pH meters in the form of photometers, measuring strips and probes. For measuring the pH value - acidity of the swimming pool water. The absolute TOPPER is the new one Swimming pool meter APP from Ondilo

The importance of the pH value of the swimming pool water cannot be stressed enough. The acidity of the water determines whether it is present chlorine properly disinfect the pool water.

The ideal pH value to measure with a PH meter for swimming pool water pH 7.3. If your pH value is too high, you can lower it with pH min, if your pH value is too low, you can raise it with pHplus.

The importance of the pH value - acidity of the pool water

The importance of the pH value of the swimming pool water cannot be stressed enough. The acidity of the water determines whether the chlorine present properly disinfects the swimming pool water.

What is the pH value?

What is the pH value?

The pH value is the acidity or acidity of the swimming pool water. A neutral pH value is a pH value of 7. A high pH eg pH 10 is basic (soapy water or eg chlorine/bleach water). A low pH eg pH 4 is acidic (eg cola or lemon juice).

Technical - chemically the pH value is the - log H+ ions. More information about the pH value can be found here.

What is the ideal pH value for swimming pool water?

The ideal pH value for swimming pool water is pH 7.3. If your pH value is too high, you can lower it with pH minus, if your pH value is too low, you can raise it with pH plus. Swimming pool products for the pH correction are available in both liquid and powder form.

Types of pH meters

pH value can be measured with

  • a PHOTOMETER
  • a POCKET PH METER
  • TEST STRIPS
  • POOL METER APP
  • a pH MEASURING PROBE

With the photometers you can usually analyze different parameters and are very suitable for public swimming pools. The pocket pH meter is fast, simple, waterproof and digital. The test strips are the simplest, cheapest but least accurate pH measurement. The Ph measuring probes are for automatic dosing systems.

How can I calibrate the pH meter?

To have a pH meter accurately measured, it is best to calibrate it 2 to 3 times per season. This calibration is usually a 2-point calibration with calibration fluid.

Swimming pool meter of the future

A number of new swimming pool meters have recently come onto the market that combine measuring with an APP on your smartphone. This makes measuring and adding the products super easy. The Ondilo ICO is the new pool meter we sell. 

This pool tester measures

  • the pH (acidity)
  • the chlorine value
  • the salinity
  • the temperature

From your pool water. The measurement is done automatically and online. The device synchronizes the measured values in the APP via WiFi, Bluetooth or Sigfox.
