LEAKChecker
Find leaks… Cut costs
LEAKChecker is an ultrasound solution designed to find compressed air and vacuum leaks in noisy environments.


LEAKChecker, in combination with LEAKReporter, provides you with a platform to detect, log, and generate reports that show how your initiatives contribute to a more sustainable environment.
