Acidity test
It allows you to quickly and economically detect the acidity (and its level) of the lubricant inside the air conditioning system.
Pack valid for 2 tests.
-
Fill one of the two containers (containing the indicator) with 10 ml of the oil to be examined.
-
Using the pipette, slowly add and shake 0,5 ml of neutralizer at a time.
-
Stop when the solution became purple.
The acidity will result:
-
LOW if we add only 0,5 ml of neutralizer (purple coloration reached after one step);
-
AVERAGE if we add 1 ml of neutralizer (purple coloration reached after two steps);
-
HIGH if we add from 1,5 ml to 5 ml of neutralizer (purple coloration reached from 3 to 10 steps).
If the purple coloration is reached after putting in the indicator container more than 5 ml of neutralizer (>0,5 x 10 steps) we need proceed with the substitution of the oil and the complete washing of the system.

Description
The acid test (or acid detection test) is a diagnostic test used in air conditioning and refrigeration systems to check whether acid is present in the refrigerant oil or system.
Technical features
-
When moisture and refrigerant mix inside the system — especially after compressor failure, overheating, or burnout — they can form hydrochloric (HCl) and hydrofluoric (HF) acids.
These acids are highly corrosive and can:
-
Damage the compressor, valves, and seals
-
Corrode metal surfaces and copper tubing
-
Shorten the lifespan of the refrigeration oil
-
Cause future system failures
