Model 753A

753A Refrigerant Leak Detector by Test Products International

The 750a features 400 hour sensor life under normal use; a spare sensor is included with each instrument for a total of 800 hours of continuous use and can detect leaks as small as 0.1 ounces per year (R134a / R22).

Whether testing for leaks in air conditioning, refrigeration, or automotive AC, the versatile 700 series spans the diverse needs of technicians, refrigeration engineers, and maintenance personnel around the globe. From freezer coils to heat pumps, experience fast, reliable results that save you both time and money.

The TPI 750a is a state-of-the-art refrigerant leak detector capable of detecting all halogen based gases. The internal diaphragm pump and unique sensor design provide fast and reliable gas sensing. Selectable sensitivity combined with an adjustable tick rate will allow any service professional to pinpoint those tough to find leaks even in contaminated environments.

Sensor life can be extended by fitting a 1/2" long piece of vinyl tubing onto the sensor tip. This tubing helps prevent foreign material from getting into the sensor during tests; clean or replace the tube regularly.

Even though TPI refrigerant leak detector sensors are very durable and can last up to 400 hours, sensor life can be aided by press fitting a 1/2" long piece of vinyl tubing onto the sensor tip. This tubing helps prevent foreign material from getting into the sensor during tests. Clean or replace the tube regularly.
