Environmental Tester PCE-228HTE
environmental tester measures for pH, Redox and temperature / 
SD memory card (1 ... 16 GB), measured values are stored in an Excel file / 
Large display / RS-232 interface and optional software for the PC

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 a SD card (in Excel format), or transferred to a PC through an RS-232 interface. An optional software and data cable for the PCE-228 pH meter 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 pH meter. We recommend the ORP-14 electrode. The environmental tester is powered by a 9V battery which is included.
