In the food industry, the pH value is an important indicator of quality, taste and shelf life in many applications. Regular control of the pH is therefore extremely important. Checking with the puncture pH meter from PCE Instruments is particularly easy, precise and reliable. With the handy puncture pH meter, solid and semi-solid substances such as meat, liquids such as milk or water and viscous media such as quark or cheese can be examined for their pH value in a very short time. The puncture pH meter is provided with a special, external electrode that is particularly suitable for use in the food sector.Puncture pH meter in use.The protection of the sensitive glass electrode by a stainless steel blade also enables solid substances to be checked. The use of the puncture pH meter is simple and, thanks to the robust and waterproof housing, unproblematic even under difficult measuring conditions. It is sufficient to immerse or insert the electrode into the measuring medium. The measurement results can then be read off quickly on the large digital display of the puncture pH meter. In order to save the currently measured value, the manufacturer has equipped the puncture pH meter with a practical data hold function. The measuring range of the puncture pH meter extends from 0.0 to 14.0 pH. The puncture pH meter can be used in the temperature range between 0 and 60 degrees Celsius and up to a humidity of 80 percent RH. To save the battery, the puncture pH meter has an automatic switch-off function: When not in use, the meter switches off automatically after ten minutes.
 

The puncture pH meter is delivered factory-adjusted, but can be calibrated at any time if necessary. This is important in order to ensure the highest possible accuracy over the entire service life. The recalibration should take place at certain intervals or after changing the pH electrode. Ideally, the user plans to recalibrate the puncture pH meter after each storage or before each use. The pH meter is delivered including the corresponding calibration solutions. The manufacturer recommends cleaning the puncture pH meter electrode with distilled water after each measurement.
