Knick 765 Laboratory pH Meter

To make reliable pH measurements easier than ever, Knick has equipped Model 765 Laboratory pH Meter with an exemplary package of safety functions and numerous practical features:

Fullcheck
Automatically checks the device functions during power-on. Also during operation, a complete instrument check can be carried out at a single keystroke. Here, also display and keypad are checked besides the electrical characteristics.

Record printouts
With record printouts of the device self-test, the calibration, and the parameter settings, it is possible (as part of quality management to ISO 9000 and GLP) to document the serviceability and the regular maintenance and calibration of the unit.

Sensoface
Checks the electrode and provides information on the electrode condition.

Calimatic
Automatically recognizes the right buffer. It allows calibration at the stroke of a key, providing ease of use and – above all – safety. You simply immerse the electrode in two buffers of the selected set, no matter which one you take first, and press the cal key. The meter automatically recognizes the buffer and calibrates itself. It does not matter which buffer solution is taken first.

Trueline
Delivers a calibrated analog recorder signal, of course electrically isolated. This provides you with a true pH signal, calibrated for the electrode and without disturbing quantizing levels, permitting undistorted recording of pH curves.

Sockets
Robust gold plated sockets are standard equipment.

EMC
EMC design protects the meter from electromagnetic interferences, ensuring reliable measurement results even under unfavorable conditions.

Temperature compensation manual or automatic
Temperature compensation is either automatic with Pt 100 or Pt 1000 temperature probes or manual, as selected.

Standard RS 232 interface
Via the standard RS 232 interface your data can be immediately processed by a computer. Even direct output to a printer is no problem.

Displaymatic for easier reading
Facilitates readout. If the measured signal changes rapidly, the running characters are blanked in order to allow easy reading. This allows you to read the currently measured value without problems.

Easy-to read LED display for two measured values
The large, bright LED display allows simultaneous readout of two measured values, such as pH and temperature.

Double insulation provides electrical safety in wet locations
The well-designed enclosure has proved successful in practical use.
