Application

TEMPRESS remote reading thermometer, types A73 and A74 are designed for all industrial and marine applications where a capillary tube between the sensor and the instrument is required.

The thermometer can be wall mounted by means of 3 lugs, panel mounted, or supplied for bracket mounting. The filling medium is an inert gas 100% environmentally neutral.

The smooth sensor can be connected by means of a compression connector with thread according to customer requirement (nipple, union or pocket). This secures great flexibility as the immersion length can easily be adjusted as desired. A fixed union with welded retaining ring is also available.

Each and every thermometer has been manufactured with great care and is hand calibrated. The high quality of TEM-PRESS instruments secures an instru-ment with great accuracy, long life and mechanical duration.
