CPS measuring instruments
General features
· User operation via LEDs and
membrane keyboard
· Membrane keyboard is resistant to most
liquids and solvents which are used in
laboratories
· 31/2 digits, 26 mm high LED display, can be
read easily even from a distance
· Simple retrofitting of a data output module -
therefore easy connection to computer or
printer
· No resolution loss via the data output module
· All functions can be activated from the computer
(bidirectional interface)
· Automatic/manual calibration or
automatic/manual temperature compensation
(selectable, depends on the measuring instrument)
· Power supply: 12 V AC/580 mA via plug-in
mains supply unit (included)
· Dimensions: 200 x 297 x 160 mm
· Weight: 1.5 kg
All CPS measuring instruments are also available
with another housing for use on the benchtop.
