Big Blu is certified for use on any grade of gas, including hospital grade oxygen. Big Blu will detect micro-leaks on thin, small micro-channel coils, as long as the leak rate is no less than 19 grams per year. You will notice tiny bubble clusters or foam cocoons start to form on the outer surface of the coil. Many competitive leak detector solutions contain glycerine or other hydrocarbons that will react with oxygen gas to produce heat, a very dangerous and possibly explosive situation.
