Vito FT440 Fryer Oil Tester

The Vito FT440 is a handheld oil testing device designed for use with commercial deep fryers. It measures two key values simultaneously: the temperature of the oil and its TPM level — Total Polar Materials — which is the standard indicator used to assess whether frying oil has degraded to the point where it should be replaced.

In a busy kitchen, fryer oil is often changed on a fixed schedule rather than based on actual condition. This leads to two common problems: oil being discarded while it still has useful life remaining, or oil being used past the point where it affects food quality and potentially raises food safety concerns. The FT440 takes the guesswork out of that decision by giving a clear, objective reading in seconds.

Using the tester is straightforward — the probe is placed directly into the oil well during or after service, and the display shows both the current oil temperature and the TPM value. This allows kitchen managers to make informed decisions about oil changes based on real data rather than habit or guesswork. Practical advantages of working this way include:

• Reduced oil consumption by avoiding premature disposal of usable oil
• Consistent food quality by flagging oil that has genuinely degraded
• A simple, repeatable process that any team member can carry out
• Useful for HACCP documentation and due diligence records
• Applicable across multiple fryer units in the same kitchen

The FT440 is a practical addition to any operation running commercial fryers regularly — from pub kitchens and fish and chip shops through to hotel restaurants and contract catering sites. It requires no installation and is used as a handheld instrument at the point of service.

If you are unsure whether this model suits your specific fryer setup, or you are looking at a broader oil management approach across multiple units, our team is happy to talk it through with you.
