I am glad to see that you test for acid; most technicians do not. For system acid you must test the oil phase and not the refrigerant. You rarely get a positive test for acid in the vapor phase unless it is a burnout. I agree with your reluctance to not use additives. Additives can and will create more problems than they intend to cure. The reason for testing a system oil for acid is to see if the dryer must be replaced. There is no better safe and proven cure than changing the dryer.

Thank you for your positive review.

This is a test to check for possible system contamination in the oil and refrigerant. It is a tool used in periodic maintenance, after a compressor replacement or shell tube rupture. Who knows what that noob did to the system before you got the call. Maybe this kit will help you undo the damage. Thanks for your comments.

Why did he crank the suction service valve open then closed for the oil test? That is always open.

@wolfofworld

The service valve was opened so oil will enter into the test vial; then the service valve is closed after oil hits the indicator. The tube can now be removed to read the result (color change) of the indicator layer.

Some "crack head" broke into my service van last night and jacked all my tools.

I've been using these for a few years and they are almost as valuable as my manifold set and DVOM when diagnosing HVAC systems. I would not show up to any service call without them.

If there is acid... I'm still a fan of just changing dryers... Alot of guys add Acid Away...

My mind is still set on If the system did not come from the factory with it DON"T USE IT... I tend to test acid levels with the little PH-strip tubes called * qwik shots* change a dryer once a week till clean... saved many compressors...

My man is HVAC certified and I am saving this for him cause he is too busy for subscribing. Thanks guys.
