Change frying oil at the right time, save money & document seamlessly: The new testo 270 BT frying oil tester enables even easier, faster & more reliable monitoring of frying oil quality thanks to its connection to the testo Smart App. With this new version, you can keep an even better eye on the TPM values of your frying oil and display and analyse all relevant data directly on your mobile device. The testo 270 BT reliably measures the proportion of "Total Polar Materials" (TPM) in the frying oil and displays this as a per cent. Thanks to the new app connection, you can seamlessly transfer your measurement results to your smartphone or tablet to ensure error-free and digital documentation. Receive instant alerts and recommendations based on your TPM measurements to optimise the quality of your frying oil. The coloured display light clearly indicates the condition of the oil: Green for a healthy TPM level, orange for a critical level and red for exceeded limits. Define individual TPM limit values and secure important instrument configurations with a PIN to prevent accidental changes. The testo 270 BT also retains its proven features: The ergonomic design protects you from direct contact with the hot frying oil. Robust workmanship: The fibreglass housing is extremely impact-resistant. In addition, the oil sensor is embedded in a metal tray and is therefore unbreakable. Easy cleaning under running water (protection class IP65). The option of self-calibration. Optimise your deep-frying processes with the new testo 270 BT and make it even easier to monitor and maintain your high product quality while reducing your oil consumption. Additional function is only available after app registration.
