UN Leak Tester

The Martin Automated Systems UN Leak Tester checks pails for small leaks using a rugged ceramic pressure transducer. This is connected to a 12-bit analog-to-digital converter. It monitors the pressure inside by inflating the pail to a pre-set test pressure and monitoring it for a pre-set time. Adjustments to the leak tester are made on an easy to understand operator terminal. Our UN Leak tester uses pressure at 3 PSI and will detect pressure drops of 1%. This accuracy enables you to consistently detect holes as small as .015″ diameter in warm pails. Throughput, depending on temperature of the pails and required accuracy is 300 per hour. At the end of its cycle, the terminal will display the pressure values as well as a Pass or Fail condition and eject the failed pails. Features a guard that fully encloses the leak tester and is constructed to Osha standards and an automatic reject station.
