Prosaris OL1 Ultrasonic Leak Locator

A smart ultrasonic sensor that transforms your phone or tablet into a visual ultrasonic leak detector in compressed air, gas and vacuum systems. The OL1 in conjunction with the Prosaris Leak Management App (Google Play) gives you all the features and tools you need to help you develop an in-house leak management program. Calculate Flow, energy loss, financial and environmental impacts in real-time.


Smart Device:OL1 connects with smart phones to capture leak data and stores it along with pictures and location tags for easy tracking and record keeping.

Visual Leak Locator:OL1 using the smartphone's camera can scan a wider industrial area, and directs you to the source of the leak.

Impact Calculator:Prosaris Leak Locator app can calculate flow, energy loss and monetary loss in real-time.

Compact and Light:OL1 weighs less than 400 gms or 1lb and fits into a handy case making it the Ultimate Smart Leak Locator.

No Training Required:No special training or trained professionals are needed to find leaks in your facility with the Prosaris OL1.

Improve Efficiency:Reduce spurious shutdowns caused by low system air-pressure, and high energy bills by employing Prosaris Smart Leak Management tools into regular workflow.

Affordable Leak Management:Prosaris OL1 is a smart ultrasonic tool that offer the benefits of expensive sonic visualizers at the cost of auditory leak detectors.
