3M Low Range Shortening Monitor Strips

3M™ Low Range Shortening Monitor Strips

The 3M™ Low Range Shortening Monitor Strips offer a fast, accurate, and easy-to-use method for checking free fatty acid (FFA) levels in frying shortening—up to 2.5% FFA. Designed for fast food restaurants, commercial kitchens, and food service operations, these strips provide a reliable way to monitor oil quality and maintain consistent frying performance.

How It Works

1. Dip the strip into the frying shortening at its normal operating temperature.
2. Observe the color bands—each yellow band corresponds to a specific FFA concentration.
3. Interpret the result at a glance: as the shortening degrades and FFA levels increase, blue bands turn yellow, clearly showing the degree of oil breakdown.

• All Fryers

• Simple one-minute test process
• Accurate colour-coded FFA readings
• Eliminates premature oil disposal
• Trusted by major food chains
