DruckTest GaWa EX



The DruckTest GaWa / DruckTest GaWa EX enables fast and accurate pressure measurements, ease of use and wide range of applications. Through 2 sensors and 3 pressure ranges the device can be used for all pressure measurements in the installation area of gas and water. As a differential pressure measuring system a positive or negative pressure relative to the atmospheric pressure can be measured. By connecting the two nipples, pressure differences can be measured. The high pressure sensor is also suitable for measurements up to 25 bar for the medium water. The DruckTest GaWa provides numerous advantages through the display of minimum and maximum values, as well as measurement times and start and end pressures in pressure tests.
