Reducing your energy costs is a difficult challenge faced by many industries in today’s economy. But, it doesn’t have to be. Undetected air or steam leaks, bearing failures and electrical panel faults cost you real money. There’s a way to cut these extra expenses from your energy bill.

SDT Ultrasound


The TRAPChecker is an ultrasound solution designed to assess the condition of steam traps and valves. The TRAPChecker detects internal turbulence by defective steam traps
and passing valves. The TRAPChecker works with SDT’s RS2 Needle Contact Sensor.


  • 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.

  • 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 colour display offers repeatable, accurate, digital measurements.

  • 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.
