3. Construction and Function
3.1 Construction
Figure
1: General View
The calibrator consists of a robust steel housing (2) with integral carrying handle (1). The display
(3) is located on the front panel of the unit. Liquid
TC calibrators have a thumb wheel (10) to
control the speed of the magnetic stirrer.
The mains inlet, switch and fuses (5) are located on the front of the unit. The service and data
interface (4) is located underneath the display (3).
During operation, cooling air is drawn in from the base of the unit (11, 12) and expelled through
grilles (7, 9). Dry
TC calibrators expel air through the top of the unit (7). Liquid
TC calibrators
expel air through side grilles (9).
The rear section of the housing contains the insulated dry block or micro bath. Heating elements,
together with an integrated temperature sensor, are used to regulate the temperature of the dry
block / micro bath. Some models contain cooling elements. These allow the temperature to be
regulated below room temperature.
