Bourdon tube pressure gauge
Test gauge series, class 0.1
Model 342.11

Applications
■■ For gaseous and liquid media that are not highly viscous
or crystallising
■■ Precision measurement in laboratories
■■ uracy pressure measurement
■■ Testing and calibration of industrial type pressure gauges
Special features
■■ Knife edge pointer and dial with mirror band scale for
optimal uracy of reading
■■ Precise movement with wear parts of argentan
■■ Particularly easy-to-read scale due to nominal size 250
■■ Scale ranges up to 0 … 1600 bar
