Refrigerant Test Strip for Ammonia Gas Leak Detection [Vial of 100 Paper Strips]

Description

• Pocket-sized, lightweight vial

• No color chart necessary

• 100 test strips

• Phenolphthalein pH Test Paper Indicator pH 8.2 – 10.0

This does NOT come with a color chart. Phenolphthalein test paper will turn pink when the ammonia in solution is from 3-5PPM. Find ammonia gas leaks by wetting one end of the test paper with distilled water and then holding it near the suspected leak.  If the color change is immediate, get a protective mask with an air supply.
