ProSource Scientific Advanced Portable pH Meters

Print
The microprocessor-based WD-35614-20 meter takes measurements in pH, mV or °C. Use mV output to take ORP readings. Other features include hold function, automatic shutoff, and ready indicator.
  • Dual display of pH (or mV) and temperature
  • Push-button pH calibration at up to five points and offset mV calibration
  • Data storage for up to 50 points
  • Includes an all-in-one single junction gel-filled epoxy body pH electrode
The microprocessor-based WD-35615-20 pH/mV/°C meter with RS-232 output includes PC software that organizes data into a file ready to import into spreadsheet software. Features include those listed above plus automatic shutoff and ready indicator.
  • Five point pH calibration with auto-buffer recognition
  • mV offset calibration
  • Recalls electrode slope and offset and previous calibration data
  • Stores and recalls 100 sets of readings with temperature
  • Hold function
  • Manual or Automatic Temperature Compensation (ATC)
  • Built in stand and optional AC adapter for benchtop use
  • Includes an all-in-one single junction gel-filled epoxy body pH electrode
