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. We recommend you use the PW 03 electrode. PCE-228-R Redox Meter is powered by batteries (one 9V battery is included in the delivery).
