Digital pressure to 400 bar \/ relative and absolute pressure measurement \/ ± 0.05% accuracy FSO \/ Storage The pressure sensor PCE-DMM 70 is a precision instrument for leakage testing. The pressure sensor is specifically designed for leak testing of pipe networks. The actual pressure sensor and the display of this precision instrument can be separated without tools. The measurement values are stored in the internal memory. In addition to the measured values the user can measuring point numbers, etc. This recording interval can be set from one second to 99 seconds. Moreover, the measured value can be stored for a specified time. The measurement and test duration and the number of measured values in the pressure sensor can be programmed. The housing of this leak detector is made of stainless steel. A special feature of this gauge is that the display and sensor are separated from each other. This has the advantage, that several sensors can be installed in the pipe network, but you can see all the values on just one display. Sensor and display are separable with no tools required.
