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 Environmental 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 Environmental 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). For the latter measurement parameter, however, a REDOX electrode must be ordered additionally. Here we recommend the ORP electrode ORP-14. The Environmental Meter is battery-operated (6 x 1.5 V batteries are included).
