Construction
The calibrator consists of a robust, black-and-red painted steel housing
and has a
carrying handle at the top
.
The front part of the housing holds the electronics of the TP17 / TPM, the controller
with
display and control elements, the thumb wheel for the magnetic stirrer
and the switch and
connection for the external reference
.
On the front side are the main switch with fuse and mains plug connection
as well as the
service and data interface
.
The grille for the exhaust air is located, in the TPM calibrators, in both the side walls of the
housing. In the TP17 calibrators, the grille is located in the upper plate of the housing in
the range of the opening of the metal block.
The rear part of the housing holds a heat-insulated calibration block with heating or cooling
elements and an integrated sensor for the reference temperature. In the case of the dry
block and multifunction calibrator, this is a metal block
and in the micro bath calibrator, it
is a tank
.
In the base, there are grilles for cooling the calibrator. The in-built fans control the inlet air
of the housing and of the calibration block .
