Frequently Asked Questions

How do I choose the right pH meter for liquids vs semi-solid foods?

For liquids, the Testo 206-pH1 is ideal thanks to its integrated temperature probe and automatic temperature compensation. For semi-solid, viscous, or protein-containing foods like processed cheese or fruit, the Testo 206-pH2 is designed specifically for that purpose, also with integrated temperature measurement. Pairing a pH meter with a Probe Thermometer gives a more complete picture of food safety conditions.

Why does a pH meter need buffer solutions?

pH buffer solutions, such as the Testo 4.01 and Testo 7.00, are required to calibrate your pH meter and ensure accurate readings. These two solutions must be purchased together, since calibration requires both reference points to check the probe across the pH scale.

Can pH meter probes be replaced if they wear out?

Yes. Replacement probes are available for the Testo 206-pH1, Testo 206-pH2, and Testo 205, each supplied with a gel storage cap to keep the pH sensor moist and protected when not in use.

How do I store a pH meter probe correctly between uses?

Storage caps for the Testo 205 and Testo 206, pre-filled with KCl (potassium chloride) gel electrolyte, keep the pH probe hydrated and extend its working life. Storing the probe dry can damage the sensor and affect the accuracy of future readings.

Is the Testo 205 pH tester waterproof?

The Testo 205 handheld T-bar pH tester features a combined pH measuring tip with temperature probe and a maintenance-free gel electrolyte, while the Testo 206-pH1 and pH2 models include a robust TopSafe protective case rated IP68 for waterproof protection.
