ACID TEST KIT MINERAL+AB+POE OILS
The acid test kit is the fastest and easiest way of checking for acid in the refrigeration compressor oil. The QwikCheck® indicator paper will change from golden yellow to pink or red when being exposed to as little as 1 part per million (PPM) of acid. It is ideal for preventative maintenance checks or for verifying proper acid clean-up after a compressor burn-out / change-out. The product replaces previous test kits.
Description
The Acid Test Kit Mineral + AB + POE Oils is a quick and accurate diagnostic tool for detecting acid contamination in refrigeration and compressor oils. It is specifically designed for use with mineral, alkylbenzene (AB), and polyolester (POE) oils, making it suitable for all common refrigerants and compressor systems.
The QwikCheck® indicator paper provides instant visual feedback. When exposed to acid, the paper changes color from golden yellow to pink or red, depending on the concentration of acid in the oil — even as low as 1 part per million (PPM). As a result, technicians can easily confirm whether a system is contaminated and take corrective action before costly damage occurs.
This acid test kit is also ideal for post-burnout clean-up verification, ensuring that all residual acid has been neutralized before recharging a compressor system. Furthermore, it is simple to use and requires no additional equipment, making it a convenient field test for marine, offshore, and industrial HVAC systems.
Features and Benefits
-
Fast and accurate detection of acid in compressor oil
-
Easy to use with clear color change indicator
-
Works with mineral, AB, and POE oils
-
Suitable for all refrigerants and lubricants
-
Detects as low as 1 PPM of acid contamination

Directions for Use
-
Insert the indicator paper into the suction side of the vapor service valve while the system is operating.
-
Allow vapor to flow through the QwikCheck® strip for 7–9 seconds.
-
Observe the color change:
-
Yellow – no acid detected
-
Light red – moderate acid contamination
-
Dark red – heavy acid contamination
-
If no color change occurs, the system is acid-free and safe to operate.
