This range of instruments includes indicating and controlling professional thermometers using the gas expansion principle.
The measuring principle relies on the fact that a non toxic gas expands with increasing temperature. The resulting increase of pressure in a closed system produces a pointer deflection directly proportional to the change in temperature.
SIKA precision dial thermometers with gas filling are produced in accordance with DIN EN 13190 class 1.
Gas filled instruments have a minimum industrial bulb diameter of 6 mm subject of course to the length of immersion.
Exact measuring results obtained by a ambient temperature between -25 and +60°C.
SIKA precision dial thermometers cover the ranges between -60 and + 600°C.
