We offer a variety products for detecting water, ammonia & hydrogen sulfide (H2S) leaks. Our three types of water sensitive sheets are the most popular. If you aren't sure what your problem requires, start with our 3 sheet sampler.
Litmus paper sheets (8x10; 200x250mm) can be used instead of our universal pH paper. Blue litmus paper can detect acidic (pH) leaks & red litmus paper can detect alkaline (pH) water leaks. Read our blog "How Does Litmus Paper Work? Not Like pH Strips?" to understand their limitations.
Ammonia refrigerant leaks detection use phenolphthalein test papers. Glovebox isolators use ammonia to detect tiny, pinpoint leaks with bromothymol infused detection cloth.
Lead acetate (Pb(C2H3O2)2) strips react with hydrogen sulfide in air or dissolved in water.

Water leak detection paper can be used as is. Place it under the suspected leak source. Or cut it into to smaller strips if needed.
Phenolphthalein & lead acetate papers can be used as is for detecting ammonia or hydrogen sulfide dissolved in water. They should be wetted first for detecting either in air.
