3M LRSM test strips for determining oil quality (50 strips/tube)

3M LRSM (Low Range Shortening Monitor) test strips are a simple and reliable system for monitoring the quality of frying oil.

The process is suitable for large food retail chains and fast-food businesses that use the same oil for the same foods repeatedly.

Repeated use of frying oil continuously reduces its quality, thereby creating a quantity of free fatty acids (FFA).

LRSM test strips detect their immediate concentration, thereby indicating the degree of reduction in oil quality.

Use: Immerse the test strip with all test markings into the heated oil (at an operating temperature of approx.

160 to 200 °C) for 1–2 seconds and remove it.

After 30 seconds, you then read the color change on the test markings, which indicate the concentration of free fatty acids as a percentage, and thus indirectly determine the condition of the oil for further use.
