Working with the pH measuring strip
Measuring the pH value made easy
You probably also learned how to use the pH measuring strip at school. It is held in a solution or semi-solid medium and shows the current pH value. However, such a test strip is not precise enough for research work or industrial production. That is why Testo offers precise and highly sensitive devices that replace the usual pH measuring strips and have proven themselves wherever extreme precision and efficiency are required.

PH measurement
Whether in different media, with fixed or connectable probes: modern devices for measuring the pH value make simple pH measuring strips made of test paper superfluous. The modern type of pH measuring strips is reflected in a device that can be used in environmental technology as well as in the food and pharmaceutical industries.
The measurements with the reactions previously known from pH test strips are simple and possible in no time at all:
Combined measurement of pH value and temperature
Measurements in aggressive media
Use of the combination electrode (measuring and reference electrode installed in one unit)
Important parameter determined safely and easily
The simultaneous measurement of temperature and pH value is particularly important in the food industry, where both parameters must be constantly monitored in order to detect changes in good time.
A measuring device that simultaneously displays different values is therefore indispensable. A simple pH measuring strip could not do this! Especially in laboratories, corrosive or acidic solutions often have to be determined. The pH value can be measured using pH measuring strips, but much more efficiently using devices such as those from Testo. Aggressive solutions can be reliably measured using a probe that is plugged into the measuring device or is already permanently installed.
Individual probes can be connected for special applications, making the measuring device sufficiently equipped for all requirements.
Measuring device for the pH value: pH measuring strips in the industry
Particularly in the food industry, but also in the pharmaceutical industry, extreme precision is required when measuring the pH value. Normal pH measuring strips as test strips are not precise enough, which is why sensitive measuring tips are required on the measuring device. At the same time, the measuring tips are designed for different media and can therefore measure viscoplastic substances as well as semi-solid media.
Of course, liquids can also be measured with the pH measuring strips, but here too the measuring instruments from Testo prove to be significantly more accurate, simpler and safer in determining the pH value. The ideal probe is available for every application and various probes make the measuring instrument an all-rounder. Testo also offers the necessary accessories, including pH measuring strips.
Determine pH value: You should pay attention to this
At school, pH measuring strips once had to be handled with care. Even the pH value of the skin could falsify the desired measured value.
pH measuring strips are therefore not well suited for use in industry and pharmacy, as they are too sensitive and do not guarantee reliable measurement results in every case.
If the pH values are to be used to make reliable statements about the character of a substance, whereby the acidic, neutral or basic properties of the same are concerned, the pH measuring strips must react absolutely reliably and safely, free from falsification and in a short time.
pH value measurement with Testo devices allows exactly that. Testo devices can be found in the food industry as well as in chemical and pharmaceutical laboratories and in research and science.
Normal pH measuring strips allow the character of a substance to be classified as acidic, basic or neutral and the corresponding gradations by changing the color of the test strip. Red usually means acidic, the blue coloration stands for an alkaline character. Green is the neutral substance, the transitions to the individual properties are shown with colored shades.
pH value measurement during food preparation
Do you know the frying oil tester? This is not a person who tastes used frying oil, but pH measuring strips. The measurement of frying oil is one of the most common of its kind in the catering industry, as the assessment of appearance and smell alone is not conclusive. The use of pH measuring strips is necessary to reliably determine the quality of the oil. The tester works without the use of chemicals and relies on capacitive sensors for the oil. Measurements are also possible in hot grease, whereby the special design of the tester ensures that pH value measurement is completely safe. Measuring the values allows a decision to be made as to whether the oil can continue to be used or needs to be replaced. This prevents unnecessary oil changes, which in turn reduces costs for your company.
