We have a variety of liquid dye gas detectors that can identify if harmful gases have leaked into water piping systems. This gas leak detector works when a few drops of the dye are added into the system, and if bubbles start forming, than that means there is leakage. Our products can test for alkyl benzene, mineral oil, petroleum, synthetic oils, and they are compatible with most types of tubing, pressure tanks, refrigeration lines, and valves. We have all purpose gas detector dyes, and ones that test for specific substances. Along with our refrigerant leak detector selection, we have gas analyzers and combustion analyzers.
