Description
Versatile in application
Nowadays, fast and simple testing of thermometers is a
“must” when it comes to the operational safety of machines
and plants.
The portable calibrators of the CTD9100 family are particularly
suited to local calibration tasks and extremely user-friendly.
Due to their compact design and their low weight, the
instruments can be taken and used almost anywhere. The
CTD9100-375 in particular is characterised by its robust case
design and compact dimensions.
Temperature dry-well calibrator model CTD9100-375
Easy to use
The temperature dry-well calibrators of the CTD9100 series
work with temperature-controlled metal blocks and interchangeable inserts.
The calibration temperature, adjusted simply using two keys
on the controller, can be very quickly controlled. The set
temperature of the heating block is displayed on a large,
4-line, high-contrast LED display. Thus reading errors are
virtually eliminated.
The new instrument concept brings together a stable heat
source with precision Pt100 temperature measurement. This
enables industrial temperature probes to be calibrated even
more eciently. Regular monitoring of temperature probes
helps to recognise failures promptly and shorten downtimes.
Thermometers with dierent diameters can be tted into the
calibrator using inserts, drilled to suit. A new block design,
with improved temperature homogeneity at the calibrator's
lower range, leads to smaller measurement uncertainties.
