The PCE-228 Environmental Tester is an easy-to-use handheld device for measuring pH, mV, °C, and °F. With the PCE-228 Environmental 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 Environmental Tester are available as optional accessories to transfer data to a computer. Temperature compensation in the PCE-228 Environmental Tester can be done manually or automatically by way of the temperature sensor, which is included.
The Environmental 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 Environmental Tester. We recommend the ORP-14 electrode. The Environmental Tester is powered by a 9V battery, which is included.
