The company’s Acid Test Kit can be used with all types of refrigerant oils, says the manufacturer. With this product, a technician only has to carry one acid test, rather than different tests for different oils, the company says. The kit determines if the oil contains any acid that could be harmful to an operating refrigeration system. The color indicators make it easy to see if the oil has no, moderate, or high acidity, says the company. The kit includes four tests per container.
