TPI 750A is a highly accurate HVAC refrigerant leak detector that uses a Corona discharge type sensor to detect all existing refrigerants and blends including 404A, Puron 410A, and R-507 (AZ50).  The TPI 750A would be perfect for any service technician working with refrigeration, cooling units or automotive A/C systems to locate leaks and repair them.

Key Features:
  • Detects all existing refrigerants and blends including 404A, Puron 410A and r-507 (AZ50)
  • Sensitivity of 0.2 oz. / year for R22 or R134A
  • 400 hours of individual sensor life; a spare sensor has been included for a total of 800 hours of continuous sensor use
  • 1 year warranty
The 750A HVAC refrigerant detector has an easy to use one-hand operable thumb wheel to adjust the “tic” rate to accurately pinpoint small leaks by eliminating background concentrations. The leak detector has an impressive sensitivity of 0.2 oz. / year for R22 or R134a.  The refrigerant detector has both an audible and flashing LED indication to indicate high concentration of refrigerant gas.  In addition, the technician can easily switch from high to low sensitivity for better accuracy in locating a leak.

The flexible 16” gooseneck probe is able to reach in difficult to get to areas.  The A/C leak detector field replaceable sensor has a sensor life of about 400 hours, but TPI has included an extra sensor to give the technician about 800 hours of continuous use for the 750A refrigerant leak detector.  The 750A is operated by two “C” type batteries and has a 1 year limited warranty.

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 750A includes:
  • 750A
  • Extra sensor
  • Two "C' batteries
  • Instruction manual
  • Soft pouch carrying case
  • One year warranty
