TPI-753a Incorporated With Pump
Generally, refrigerant leak detectors with pumps respond and clear faster as you enter or leave the leak area. This is most important when locating small leaks.
TPI-753a Can Detect SF6
Sulfer hexafluoride (SF6) is used in high voltage insulation as found in high voltage lines and circuit breakers. SF6 is toxic and emitted into the air when high voltage insulation begins to degrade. The 753a will detect SF6 at a level of 750 ppm or higher.
Technical Tips:
Even though the sensors are very durable, you can extend the sensor life of your leak detector. Simply fit a ½” long piece of vinyl tubing onto the sensor tip. This will help prevent foreign material from getting into the sensor during tests. Clean or replace the tube regularly.
Is there a way to determine how many parts per million (ppm) a leak of 0.1 ounce per year(oz/yr) is?
A leak of 134a refrigerant measuring 0.1 oz/yr is equivalent to approximately 380 to 400 ppm. A leak measuring 0.2oz/yr is equivalent to approximately 760 to 800 ppm.
