The TPI 753A is an easy to use, push button, state-of-the-art refrigerant leak detector that can detect all existing refrigerants and blends including the 404A, PURON, and R-507 (AZ50). This refrigerant leak detector can also be used to detect SF6 at a level of 750ppm or higher. The 753A is used by service technicians, refrigeration engineers, and maintenance technicians to test for leaks in air conditioning, refrigeration, or automotive A/C systems.

Key Features:
  • Sensitivity of 0.1 oz /year 
  • Detects all existing refrigerants and blends including 404A, PURON, R-507 (AZ50)
  • Detects SF6 at levels of 750ppm or higher
  • 400 hours of sensor life; a spare sensor included to give a total of 800 hours of continuous sensor use
The 753A HVAC leak detector has an AIT micro tip sensor that has a sensitivity of 0.1 oz. /year for R22 or R134A refrigerants. The instrument will emit both an audible and visible indication when a leak has been detected.  The leak detector’s internal pump allows for a faster response and clears quicker to help the technician quickly pinpoint a refrigerant leak even in a contaminated environment. In addition, a technician can switch from high to low sensitivity to quickly and accurately find a leak.

This A/C leak detector has a flexible 16” gooseneck probe that can easily reach into difficult areas. The field replaceable sensor has a lifespan of about 400 hours, but TPI includes an extra sensor so a technician has about 800 hours of continuous sensor use.  The 753A is operated by 2 “C” size batteries.

TPI technicians suggest to fit a ½” piece of vinyl tubing onto the sensor tip to prevent containments getting onto your sensor when testing.  You should clean or replace the little plastic tube when it gets dirty.  This suggestion could help extend the life of your sensor.

TPI 753A includes:
  • 753A
  • Two Sensors
  • Two “C” batteries
  • Soft pouch
  • Instruction manual
