testo 270 BT – Professional Cooking Oil Quality Control Made Simple
The testo 270 BT is a next-generation solution for professional kitchens that demand consistent food quality, cost efficiency and full compliance. Designed for fast, reliable frying oil analysis, this intelligent device removes guesswork and helps you change oil only when it is truly necessary.
Unlike visual or odour checks, the testo Cooking Oil Tester measures Total Polar Materials (TPM) directly in hot oil, delivering an objective percentage value that clearly indicates oil condition. This means better tasting food, safer frying processes and significant savings on oil usage.
Smarter Oil Monitoring with the testo 270 BT
The testo 270 BT connects seamlessly to the free testo Smart App, transforming oil quality measurement into a fully digital, error-free process. Measurements can be taken with or without the app, but when connected, the testo Cooking Oil Tester unlocks advanced documentation and analysis features that are ideal for professional kitchens, chains and food service operators.
With Bluetooth connectivity, all TPM readings are transferred automatically to your smartphone or tablet. You can export data as CSV files or generate professional PDF reports with comments and signatures for HACCP compliance, audits and internal quality assurance.
Clear Results, Instant Decisions
The testo 270 BT uses an intuitive multicolour LED display to show oil quality at a glance:
- Green – oil quality is good
- Orange – critical TPM level approaching
- Red – limit exceeded, oil change required
This clear visual guidance allows kitchen staff to act immediately and consistently. Individual TPM limit values can also be set, and critical instrument settings can be protected with a PIN to prevent accidental changes. This makes the testo Cooking Oil Tester ideal for busy commercial environments where accuracy and consistency matter.
Designed for Safety, Durability and Ease of Use
The testo 270 BT has been engineered specifically for use in hot frying oil. Its ergonomic design keeps hands safely away from heat, while the robust fibreglass housing and metal-encased sensor ensure exceptional durability. The device is fully IP65 rated, allowing quick and easy cleaning under running water.
Self-calibration can be carried out on site using the supplied reference oil via the app, ensuring long-term accuracy and confidence in every measurement. This makes the testo Cooking Oil Tester not only reliable, but also extremely cost-effective over its lifetime.
