What the TFT Upgrade Delivers
Improvements over the standard IIT 4500 — display quality, conversion accuracy, response speed, and load cell capacity.
7" Multi-Colour TFT Display
Full-colour 7-inch TFT screen replaces the standard character LCD. Weight readings, ticket data, and status information displayed with colour differentiation for clarity.
24-bit Sigma-Delta A/D Converter
Higher resolution analogue-to-digital conversion compared to standard terminals — delivers superior signal accuracy and stability.
25 Samples Per Second
Internal conversion speed of 25 samples per second provides fast, stable, and responsive weight readings — minimal stabilisation wait time.
Drives Up to 12 Load Cells
Load cell excitation capable of driving up to 12 load cells of 350Ω input resistance — supporting large multi-cell weighbridge configurations.
