The Environmental Tester PCE-228 is a very easy-to-use pH / mV / °C / °F handheld instrument. The pH value and the temperature can be stored directly on the SD card (Excel file) or transferred via the RS-232 interface directly from the Environmental Tester to a PC. For this, we optionally offer software and the suitable RS-232 interface cable as accessories. Temperature compensation is either manual or automatic via the supplied temperature sensor.
All this allows fast and reliable pH measurement. The Environmental Tester has a three-point calibration, which is performed automatically. It can be determined with the combination meter, the pH, the temperature, or the REDOX potential (ORP). For the latter measurement parameters, however, a REDOX electrode must also be ordered. Here we recommend the ORP electrode ORP-14. The Environmental Tester is battery powered (6 x 1.5V batteries are included).
