PCE Instruments 228 Water Analysis Meter for pH Value, Redox and Temperature

Model # 228

The PCE-228 environmental meter is a very easy-to-use handheld pH / mV / °C meter. The pH value and the temperature can be saved directly on the SD card (Excel file) or transferred directly from the pH meter to a PC via the RS-232 interface.
For this purpose, we optionally offer software and the appropriate RS-232 interface cable as accessories. The temperature compensation takes place either manually or automatically using the temperature sensor supplied.
All of this allows a quick and reliable pH measurement. The pH meter has a three-point calibration, which is carried out automatically. The combination measuring device can be used to determine the pH value, the temperature or the REDOX potential (ORP).

The combination measuring device can be used to determine the pH value, the temperature or the REDOX potential (ORP). For the latter measurement parameter, however, a REDOX electrode must be ordered additionally. Here we recommend the ORP electrode ORP-14. The pH meter is battery operated (6 x 1.5 V batteries are included).
