I work ammonia refrigeration and these work perfect for finding small leaks. Just wet the paper and when turns purple ammonia is present. Simple easy and effective. For the price 100 of these will last for a long time. The 2-5ppm range makes finding small leaks easy. Must buy for anyone in this field
