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 for on-site calibrations and extremely
user-friendly. Due to their compact design and their low
weight, the instruments can be taken and used almost
anywhere.
The new
source with an intelligent air cooling system, which easily
keeps the temperature low in the upper part of the calibrator.
This enables industrial temperature probes to be calibrated
even more eciently, without overheating the process head
or the handgrip of the thermometer. Regular monitoring of
temperature probes helps to recognise failures promptly and
shorten downtimes.

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
buttons on the controller, can be very quickly controlled.
The actual temperature of the heating block is displayed on
a large, 2-line, high-contrast LC display. Thus reading errors
are virtually eliminated.
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.

1) Is dened as the measuring deviation between the measured value and the reference value.
2) Maximum temperature dierence at a stable temperature over 30 minutes.
3) Maximum temperature dierence at 40 mm above the bottom.

Inserts
1. The ceramic insert has several bores into which the thermometer probes being
calibrated and one of the additional customer reference thermometers, for
comparative calibration, can be inserted. The block is either heated or cooled
to the desired calibration temperature. Once a stable temperature has been
reached, the temperature probes to be calibrated can be compared with the
reference thermometer. The documentation of this comparison represents the
calibration.
2. The ceramic insulator is tted onto the insert and its bores are aligned with
respect to the insert. This prevents the handgrip or process head of the
thermometers from overheating.
3. Replacement tools for removing or placing the ceramic insert. The insert must
be aligned in such a way, so that the grooves sit directly over the controlling and
monitoring thermometers.
