Depending on the medium, pH measurement can become a challenge. Testo's high-precision pH meters have proved themselves everywhere where particularly reliable and efficient pH measurements are required.
Ideal for the measurement of the pH value in semi-solid, viscoplastic and liquid media.
Fast, easy pH and temperature measurement with just one measuring probe.
Also the best solution for sensitive applications, for instance in the food or pharmaceutical industries.
Testo's pH meters impress thanks to outstanding performance and an unbeatable price-performance ratio.
Where would you like to determine the pH value? pH meters for every application
The pH value is an important parameter for numerous applications, whether in the pharmaceutical industry, environmental technology or the food sector. With a Testo meter, pH measurement becomes high-precision in next to no time. Regardless of whether the medium is hot, viscous or aggressive. And a little more information makes the measurement process even more efficient!
Besonderes in der Lebensmittelproduktion spielen pH-Wert und Temperatur eine wichtige Rolle. Arbeitsprozesse werden effizienter, wenn Sie beide Parameter in einem Messvorgang kontrollieren. Hier ist ein Messgerät sinnvoll, mit dem Sie gleichzeitig den pH-Wert bestimmen und die Temperatur messen können. Testo bietet eine große Vielzahl an pH-Messgeräten mit fest integriertem oder anschließbarem Temperaturfühler speziell für Fleischer und Bäcker.
Extremely acid, in other words caustic, chemicals often occur in chemical and pharmaceutical laboratories. This means you need a meter with a probe that is resistant to aggressive media for measurement of the pH value – and also the temperature. Many of Testo's pH meters offer the advantage of you being able to connect external probes for special applications. This means you are ideally equipped for every application.
The advantage of a single-rod measuring cell is that the measuring and reference electrode are installed in one unit. This means you only need one measuring probe for pH measurement, even with the additional integration of a temperature sensor. This design has established itself in practice, because it is considerably easier to handle in comparison to the separate set-up. In addition, probes of this kind have a very long service life.
The pH value is an important indicator in numerous chemical and biochemical reactions and stands for "pondus hydrogenii" - hydrogen weight. Why?
The pH value quantifies the concentration of hydrogen ions in or on a medium. To do this, the hydrogen ion concentration is converted to electrical voltage.
The pH value scale ranges from 0 = extremely acid (e.g. hydrochloric acid) to 14 (extremely alkaline, such as sodium hydroxide).
The pH readings enable precise statements about the acid or alkaline character of a substance, or its neutrality at a pH value of 7. This means consistent quality of food or drugs can be guaranteed.
In purely arithmetical terms, there are also pH values which are above or below the scale. However, they have no practical significance.
pH measurement in the food industry not only needs to be particularly precise, but also requires versatile measuring instruments. Because it has to be possible to use them for a really wide variety of media: for semi-solid substances, such as meat, for viscoplastic media such as jelly, quark or cheese and of course for liquids such as milk, drinks or water. You will find the best possible probes and sensors for every application at Testo. And everything else which you need in terms of accessories and consumables.
Cooking oil measurement is one of the most common routine measurements in catering. Just a visual inspection or checking the smell is not enough for you to be able to assess whether the quality of the cooking oil is still perfect and meets the legal requirements. A Testo cooking oil tester makes the quality test lightning fast for you – and without any chemicals. Capacitive oil sensors and a special design enable measurement in hot fat and in the process protect users from the hot deep fat fryer. A large illuminated display clearly shows whether the critical TPM values have been reached. You therefore save unnecessarily frequent replacements of the cooking oil based just on suspicion. And, from a long-term perspective, your costs for cooking oil can fall by up to 20%.
