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 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.
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 and set temperature of the heating block can be
displayed simultaneously on a large 4-digit, 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. The large insertion depth of 150 mm [5.91 in]
considerably reduces heat dissipation errors.

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 [1.57 in] above the bottom.
4) Maximum temperature dierence between the bores (all thermometers inserted to the same depth).
5) Time before reaching a stable value.
The measurement uncertainty is dened as the total measurement uncertainty (k = 2), which contains the following shares:
accuracy, measurement uncertainty of reference, stability and homogeneity.
