PCE-228-R Redox meter / Portable Redox Meter, for both pH and temperature values / RS-232 interface and optional software 

PCE-288-R Redox Meter is a very easy to use meter to measure mV / pH / ºC. In the PC-228-R Redox Meter values can be directly stored in the SD memory card (Excel format) or can be directly transferred in real time to a PC or laptop by means of the RS-232 interface. Both Redox value and temperature can be directly transferred to a PC by means of the RS-232 interface, so we offer you software and a RS-232 data cable as additional components. Temperature compensation (function available only for measurements of pH) can be made by hand or automatically by means of a temperature sensor included in the delivery of the Redox Meter. So, all the previously mentioned characteristics provide this Redox Meter with a high reliability. The PCE-228-R Redox Meter has a three-point calibration. Redox, temperature and pH values can be determined by means of the combined meter. To determine the pH value an additional pH electrode must be required. We recommend you to use the PW 03 electrode. PCE-228_R Redox Meter is powered by batteries (one 9V battery is included in the delivery).
