pH Meter / pH Tester PCE-228M
The pH Meter / pH Tester PCE-228M is a very easy to use hand-held pH meter for food. At the pH Meter / pH Tester, the pH value and the temperature can be read off via the large LCD display or saved to the SD card (Excel file). Another option is the online transmission via the RS-232 interface directly from the pH Meter / pH Tester to a PC or laptop. For this, we offer optional software and the appropriate RS-232 interface cable as an accessory.
The temperature compensation is carried out either manually or automatically via the supplied stainless steel temperature sensor. All this allows a fast and reliable pH measurement of all foods, e.g. sausage, meat, and cheese. The pH Meter / pH Tester has a three-point calibration, which is performed automatically. The pH meter is battery operated (6 x 1.5 V batteries are included). The pH-Meter PCE-228M is ideal for occasional pH measurements in the laboratory.
The modern world is defined by tough competition between the manufacturers and sellers. In addition, more and more strict requirements and norms of the official state organizations and institutions must be met in order to present the product on the market. The quality of food products and beverages is of crucial importance, since it concerns the safety and health of large numbers of people, and just a few mistakes and discrepancies in production may lead to serious consequences, from just bad taste or short storage life to bacterial infections and poisoning. All these possible factors lead to the loss of reputation and serious financial expenses. Nowadays monitoring the quality of the produced products has become easy, and the application of the correct testing and measuring equipment like, for example, a pH Meter / pH Tester, provides the manufacturer as well as the customer with reliable information about the quality of each particular product.
pH level is important not only in water, it relates to all manufactured and processed foodstuffs, as well as beverages and spirits (for example, wine or beer).
An important thing is that a pH Meter / pH Tester should be applied at all the stages of production, even for the measurements in the raw material. A pH Meter / pH Tester allows for exact monitoring of the slightest changes in the pH value in the product in the process of fermentation, brewing, heating, boiling, mixing with additives, and other ingredients etc. Such parameter as pH may substantially influence the texture and character of the product; it applies, for example, to dairy products, like yoghurts or cheeses. All the food products with low pH values belong to the acidic products. If some tinned products or sauces require more acid, the pH level in them is reduced on purpose, so that to create the required acidified medium. To leave the pH value at the high level, over 4.5, may be dangerous, since this makes the favourable conditions for bacteria growth. Biochemical processes occur inevitably during the production and storage of the foodstuffs. pH value, or the concentration of hydrogen ions, can be a tool for controlling these processes. There is no one particular average value applicable for all products. Beer (4-5), wine (2.7-3.8), cheese (4.6 – 6.8), meat, juices etc – for each of the food categories there are their own ranges of the desirable pH values, and application of a pH Meter / pH Tester helps to maintain them on the correct level or adjust if the current parameters deviate in the process of manufacturing.
