Overview It is used to determine the leak tightness of elastomeric sealing ring type of joints for buried thermoplastic non-pressure piping systems. Characters 1.Industrial color LCD display is convenient to input and check test information, including test parameters, test results and test curves, etc. 2.Test data can easily be exported to user's PC via USB stick for further processing and report generation. 3.Hydraulic type pipe deflection device at radial direction, high precision digital gauge display as well as the self-aligning centering function ensure the operation easier. 4.Different supporting-blocks are introduced for different pipe fittings. 5.Angular deflection at four directions can be collected. 6.Unique design for sample clamping system makes the sample installation more convenient. Standard ISO 4422-2:1996, ISO 13844:2000, DIN EN 1277 and the equivalent.
