Automated calibration tool for tablet hardness testers
Streamline your tablet hardness testing with a tool that automates calibration, eliminating the need for external PCs or software, and ensures precision right from the testing station’s interface.

The AutoCal 2.0 from ERWEKA GmbH is an innovative calibration tool designed to streamline the calibration of hardness testers. This system stands out by eliminating the traditional use of weights and external PCs, using a certified load cell that connects via USB. Operable directly from the tester’s keypad, it automatically adjusts and checks linearity across up to three points, ensuring precision in pharmaceutical tablet production. Ideal for laboratory and processing departments, AutoCal 2.0 integrates seamlessly into existing setups, facilitating automated, hassle-free calibration. Its robust design supports a variety of solid and powder forms, while the documentation feature enhances audit readiness in compliance-driven environments.
