The PCE-228 pH Meter / pH Tester is an easy-to-use handheld device for measuring pH, mV, °C, and °F. With the PCE-228 pH Meter / pH Tester, both temperature and pH values can be directly stored onto an SD card (in Excel format), or transferred to a PC through an RS-232 interface. Optional software and a data cable for the PCE-228 pH Meter / pH Tester are available as optional accessories to transfer data to a computer. Temperature compensation in the PCE-228 pH Meter / pH Tester can be done manually or automatically by way of the temperature sensor which is included.
The pH Meter / pH Tester has two calibration points. The calibration can be done with the trimmer on the side of the device, which is protected under a cover. With this combined device, the user can determine pH value, temperature, or Redox potency (ORP). For the latter measurement parameter, a Redox electrode must be ordered separately from the PCE-228 pH Meter / pH Tester. We recommend the ORP-14 electrode. The pH Meter / pH Tester is powered by a 9V battery, which is included.
