PCE Instruments has recently added four new versions to its PCE-228 range of ph meters for liquid measurement. The basic model PCE-228 comes with a PE-03 pH electrode and a temperature sensor, with other variations available for measurement in meat and other food products, Redox measurement and pH measurement of soil.
Electrodes are interchangeable with the new models, and all of the new models are available with accessories such as solutions (storage, calibration, cleaning, etc.), different types of mains adaptor, an RS-232 to USB adaptor and more. An ISO calibration with certificate can be purchased at an extra charge.
The PCE-228SF pH meter measures pH values on surfaces with its ERH-115 electrode and also comes with a temperature probe. Measurable surfaces include skin, paper and cardboard, textiles, etc. This pH tester also measures very small sample volumes, starting from 0.1 ml. To do so, a special cuvette is needed. The cuvette is also included in the standard package of the PCE-228SF pH meter.
The PCE-228LIQ comes with the PCE-PH-LIQ electrode and the standard temperature probe, as all other models. The PCE-228LIQ is used to measure pH values in beer, blood and some dairy products.
The pH tester PCE-228SLUR comes with the PCE-PH-SLUR pH electrode for measuring pH in mud and soil and a temperature sensor.
In cosmetics, where it is very important to know that the pH value of a product like shampoo, hair dye, body spray, etc. matches the pH of the skin, the PCE-228P will be the right pH meter to choose. It comes with the IJ-44C pH electrode for cosmetics and the temperature sensor.
