Micro Leak Detector
ONE OF A KIND
BIG BLU needs very little introduction since it is used by nearly
80% of all HVAC/R Technicians throughout the U.S. and Canada.
Bubble leak detection was once considered gross and unreliable. To a
certain degree it was true because the dominant makers of leak
detector solutions relied on simple mixtures of soap and water.
BIG BLU is a strong and persistent film forming liquid that has
excelled in the field identification of gas leaks. It remains, the
only bubble/foam indicator capable of detecting micro gas leakage
down to 0.65 ounces per year.
