🧪 QwikProducts QT2000 Check Acid Test Kit Yellow: Quick and Reliable Testing for Acidity Review

works as said. The result was a severe engine fire, so I can't comment on how this might work in a more subtle situation. The paper was bright red to me.

This is a great way to confirm if moisture has entered the HVAC system. I was running an R410a system that had lost so much charge that it was creating a vacuum in the suction line and I was concerned it might attract moisture which could lead to acid build up over time. This showed me with a quick and easy test that there was no detectable acid in the system. Good product.
