Frequently Asked Questions

FAQ for Leak Detection

Simply wet phenolphthalein ammonia litmus test paper and hold it near the suspected refrigerant leakage point. Most of the time this will be at a fitting & the paper will change color. A slow leak in multiple locations along a length of pipe is much harder to detector. Try wrapping ammonia leak detection cloth around the pipe & look for tiny color changes in the cloth.

Natural gas is normally odorless. Small amounts of sulfur based compounds are mixed in to give it a faint "rotten egg" smell. You're most likely to smell it near your furnace or hot water heater. Ammonia does have its own odor distinct odor though.

Phenolphthalein test papers or ammonia leak detection cloths can both be used. Test papers help identify leaky fittings in refrigeration units. Detection cloths test the integrity of specialized isolation systems used pharmaceutical production or infant incubators, etc. Read more in our blog: Ammonia Leak Detection Methods Using Test Paper & Cloth

Use lead acetate test paper to detect the presence of H2S in your drinking, well, or ground water down to as low as 5ppm. Confirm the presence of gaseous H2S using a wet lead acetate strip.
