TRAPChecker

Keep Your Traps Shut

TRAPChecker is an ultrasound solution designed to assess the condition of steam traps and valves.

Focused

Inefficient steam systems waste energy and impact product quality. TRAPChecker is an ultrasound solution focused on finding failed steam traps. It works on every style of trap and failure mode.

Simple

TRAPChecker is so easy to use. Simply open the box, connect the sensor, and hear the difference between a good and bad steam trap. Its vibrant color display offers repeatable, accurate, digital measurements.

Affordable

As much as 40% of your steam traps could be operating in a failed state. The low entry cost of TRAPChecker and the high cost of energy, could see your investment recovered the first time you use it.
