When a more precise reading of early degradation of oil is desired, try the 3M™ Low Range Oil Quality Test Strips. This strip measures free fatty acid concentrations at 1%, 1.5%, 2% and 2.5%. Ideal for food processing applications or to help meet regulatory requirements.
These 3M™ Low Range Shortening Monitor Strips provide rapid measurement of free fatty acid content up to 2.5 per cent. The colour marks on the test strip indicate how high the percentage is. This is the ideal process for major fast food chains who always use the same oil and only single fry. The Standard Range Shortening Monitoring is also available and measures free fatty acid content up to 7 per cent.
