Exact measurement of pressure tightness and leak-proofness of gas and water systems. Testo 314 compensates pressure fluctuations to the desired normal test pressure, measurement inaccuracies are thus eliminated. The most common pipe connections are made of high-quality materials and are checked for leak-proofness by the measuring instrument (simple press of a button) before each measurement. The integrated printer offers the possibility of documenting a whole measurement series, and of presenting it as a graph. Adapted to the special demands of the documentation of usability tests, all the measurements of individual measurement locations can be archived by the Testo software and called up in the form of test protocols.
