The long-established PCE-228 from PCE Instruments offers several extra probes in addition to the pH probe.
In laboratories as well as in the industrial sector, a pH meter is often required to measure the hydrogen-ion activity in water-based solutions. The hydrogen-ion activity is indicative of a solution’s acidity or alkalinity, which is expressed as pH. The right pH electrode must be selected carefully in line with the measured medium as it will be directly in contact with it.
The basic model PCE-228 comes with a PE-03 pH electrode and a temperature sensor, whilst the PCE-228M, is available with the CPC-OSH-12-01 pH electrode for meat and other food products. Another existing model is the PCE-228-R with ORP-14 electrode for Redox measurement, The PCE-228S pH variation comes with the PCE-PH-ES electrode for pH measurement in soil. For all four products include a temperature probe, with additional probes available as an option.
PCE Instruments has added four new versions of the PCE-228 to its range. The PCE-228SF pH 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 tester measures very small sample volumes, starting from 0.1 ml. The special cuvette required for this process is included in the standard package.
The PCE-228LIQ, used to measure pH values in beer, blood and some dairy products, comes with the PCE-PH-LIQ electrode and the standard temperature probe. The PCE-228LIQ, suitable for measuring pH in mud and soil and a temperature sensor, comes with the PCE-PH-SLUR pH electrode.
In cosmetics, where it is very important to know that the pH value of products such as shampoo, hair dye and body spray match the pH of the . The PCE-228P with IJ-44C pH electrode would be the right choice.
All models are available with accessories such as solutions (storage, calibration, cleaning, etc.), different types of mains adaptors, an RS-232 to USB adaptor and more. Electrodes from older models are interchangeable with the new models. An ISO calibration with certificate can be purchased at an extra charge.
