(0 review)

The Wika 73x.18 Series SS Differential Pressure Gauge for Refrigeration is an essential tool for accurately measuring differential pressure or two distinct pressures in refrigeration systems and compressors. It allows for the simultaneous monitoring of vapor pressure and the corresponding vapor temperature, making it ideal for a variety of applications. This gauge is suited for gaseous and liquid aggressive media that are neither highly viscous nor crystallizing and can also be used in harsh environments.


One of the standout features of this gauge is its moving dial that indicates differential pressure. It is available with an optional duplex scale for versatile measurement capabilities. The 733.18 model features a liquid-filled case that dampens the effects of high dynamic pressure pulsations or vibrations and prevents condensation, ensuring reliable performance in demanding conditions. Additionally, the gauge can be equipped with combined pressure and temperature scales in duplex, triples, or quadruplex formats to accommodate all common refrigerants.


Branom Instrument Co. stands out as the best place to purchase this high-quality Wika differential pressure gauge. With its exceptional design and reliable performance, the Wika 73x.18 Series is the perfect solution for your refrigeration measurement needs.
