OIL-TEST is a new chemical solution that allows you to identify within seconds the type of lubricant contained in a Refrigeration or A/C system. In two short steps it is possible to identify Polyol ester (POE), Alkylenbenzene (ABZ) or Mineral Oil. OIL-TEST contains chemical elements that react in contact with the lubricant, changing its transparency, which identify the type of lubricant inside the refrigeration system. BENEFITS • Easy to use. • Minimise time and costs by eliminating the need for expensive laboratory tests. • Avoid expensive and widespread mistakes made by mixing POE and mineral lubricants. • Accurate results in seconds. • Quick check of lubricant type prior to injecting additional lubricant. • Compatible with all refrigerants. • Works with all lubricants. • Two complete tests. • Not Recommended for Automotive or Mobile A/C or Refrigeration Systems. • The plastic box contains 2 TEST.
