Knick  Laboratory pH Meter 765
Laboratory pH Meter with multiple safety functions.
  • Fullcheck® automatically checks the device functions from input socket to recorder output. With a record printout of the test it is possible (as part of quality management to ISO 9000) to document the device operability.
  • Sensoface® checks the electrode and provides information on the electrode condition. The zero, slope, response time and impedance of the electrode as well as the calibration interval are evaluated.
  • The Trueline® recorder output provides a calibrated analog recorder signal (electrically isolated).
  • The Calimatic® automatically recognises the right buffer.
  • EMC design protects the meter from electromagnetic interferences.
  • Temperature compensation is performed automatically using a Pt 100 or Pt 1000 temperature probe or manually.
  • Via the standard RS 232 interface the measured values can be immediately processed by a computer. Even direct output to a printer is possible.
  • The large, bright LED display (height 13 mm) allows simultaneous readout of 2 measured values, e.g. pH and temperature.
  • Supplied without accessories!
