The leak detector for sewers DC 420 is a high precision, multi-functional tester for differential pressure, absolute pressure,humidity and temperature registration. The extremely largedynamic range of the leak detector for drains allows highly sensitive measurements of the smallest in the Pascal range for tensile and gas pressure measurements and leak tests on waste water pipes according to EN 1610.
