Total Polar Materials (TPM) are compounds that develop in cooking oil as it undergoes repeated heating and exposure to food, oxygen, and moisture. Monitoring TPM provides a measurable way to assess frying oil degradation instead of relying only on visual appearance or smell.
The Testo 270 BT combines TPM measurement, temperature measurement, Bluetooth connectivity, digital documentation, color-coded alerts, custom limits, and self-calibration in one portable instrument. Its IP65-rated housing and ergonomic design make it suitable for regular use in professional kitchen environments.
