Description
These innovative calibrators have been designed for on-site
applications as well as for the severe conditions of the naval
and marine sectors.
Their ease of use and their compact and practical design
make them unbeatable in industrial processes where the
calibration of the temperature measurement systems is
essential for the control of the process and the quality of the
nal product.
Special attention is paid to reduce weight, size and to
reinforce robustness by using an aluminium body as well as
aluminium and stainless steel for many internal parts.
Each calibrator is tested in our laboratory and calibrated with
our references in accordance with the international standard.
At this stage all the functions are checked against reference
parameters and a calibration protocol is issued.
Temperature dry-well calibrator CTD4000
The thermal part of these calibrators is made of a metal
block heated with resistors or with Peltier thermoelectric
modules. In the metal block there is one bore in which the
interchangeable insert is placed.
With the available standard inserts, the calibrators are
versatile and can be easily adapted for the calibration of
temperature probes with the most common diameters.
Customer-specic inserts and bores are available on request.
