The BARFLEX

®

4 portable electronic pressure gauge is a self-contained instru-ment which is ideal for measurements in the field : it has a very rugged case (epoxy-painted aluminium), is sealed against running water IP 55, and the sensor (TRANSBAR

®

0.25 % - Thim film technology 0.1 %) is compatible with the majority of corrosive fluids.The BARFLEX

®

4 guarantees immunity to electromagnetic interference (walkie-talkies, portable telephones, power switching devices, etc.).
