The APERA Instruments PH20 pH meter is an ideal, portable measuring device for determining pH levels in a wide range of applications, such as hydroponics, swimming pools, water treatment, breweries, and water analysis. With this kit, in addition to the meter, you’ll receive a complete calibration and maintenance package that allows you to keep the PH20 accurate and in good working order over the long term.

Why this kit? Regular calibration with fresh buffer solution is crucial for reliable measurements. As a rule of thumb, calibrate at least once a week, and replace any opened buffer solution after about 10–15 calibrations. With the large bottles and the handy CalBox included in this set, you can perform up to 150 calibrations—and save up to 50% on buffer solution compared to open storage.

  • Highly stable measurement in the range of 0.0 to 14.0 pH
  • Waterproof meter, IP67-rated housing
  • Simple automatic 1- to 3-point calibration with buffer recognition
  • Automatic temperature compensation (ATC) in the range of 0–50 °C
  • Large LCD with simultaneous display of pH value and temperature
  • Automatic shut-off after 8 minutes of inactivity
  • Up to 1,000 hours of operating time (4 AAA batteries)
  • CalBox for organized storage and economical dispensing of calibration solutions
  • Soft cleaning brush for residue-free, gentle probe care

The Apera Instruments PH20 pH meter has a 2-year manufacturer’s warranty (6 months on the electrode).

FAQ

How accurate is the PH20?

The PH20 measures pH values with an accuracy of ±0.1 pH and a resolution of 0.1 pH. The measurement range is 0 to 14.0 pH with automatic temperature compensation from 0 to 50 °C.

How do I calibrate the PH20?

The PH20 supports automatic 1- to 3-point calibration with automatic buffer recognition. The package includes calibration solutions with pH 4.00 and pH 7.00 (50 ml each). Calibration takes just a few minutes.

Can I replace the electrode on the PH20?

No, the PH20’s electrode is permanently installed and cannot be replaced. If you need a replaceable electrode, we recommend the PH60, which is compatible with all pH electrodes in the 60 series.

What’s included in the package?

The package includes: PH20 meter, 4 AAA batteries, 3 × calibration solutions, 250 ml (pH 4.00 / 7.00 / 10.00), 1 × KCl storage solution (3M), 250 ml, a cleaning brush, a CalBox, a carrying strap, and a carrying case.

Is the PH20 suitable for aquariums?

Yes, the PH20 is well-suited for aquariums. It measures in the pH range of 0 to 14.0, is IP67-certified (waterproof and floatable), and is easy to calibrate. For professional applications, the PH60 offers even more precise results with an accuracy of ±0.01.
