765 Laboratory
pH Meter
Quality assurance does not
stop at your lab door.

To make reliable pH measurements easier than ever, Knick has
equipped the Model 765
Laboratory pH Meter with an
exemplary package of safety functions.

Fullcheck
automatically checks the device
functions during power-on.
Also during operation, a
com­ lete instrument check can be
p
carried out at a single key­ troke.
s
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 service­ bility and
a
the regular mainte­ ance and calin
bration of the unit.
Sensoface
checks the electrode and provides
information on the electrode condition. The zero, slope, response
time, and glass impedance of the
electrode as well as the calibration
interval are evaluated.
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 un­ avorable
f
conditions.

Numerous practical features
allow comfortable and safe
pH measurement.
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
Displaymatic 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. LED display
for alphanumeric characters
allows.
Double insulation
provides electrical safety
in wet locations
The well-designed enclosure has
proved successful
in practical use. A
waterproof membrane keyboard
and drain grooves
protect the meter
from moisture. The
robust, stainless
steel covered
enclosure resists
even strong mechanical stress.
