## Overview

Design Two independent measuring systems, parallel entries in line Nominal size in mm 80, 100 Accuracy class 1.6 Scale ranges 0 ... 2.5 to 0 ... ...

## Applications

- Measurement of differential pressure or of two different pressures applied in refrigeration plants or compressors
- Simultaneous measurement of the vapour pressure and the resulting vapour temperature
- For gaseous and liquid aggressive media that are not highly viscous or crystallising, also in aggressive ambience

## Special features

- Differetial pressure with moving dial
- Design optionally with duplex scale
- With liquid-filled case for damping in applications with high dynamic pressure pulsations or vibrations and for avoiding condensation water Model 733.18
- Combined pressure and temperature scales as duplex, triples or quadruplex scales for all common refrigerants
