Laboratory hardness tester TBH II

for the pharmaceutical industry

The TBH II is a manual 5-parameter tablet hardness tester designed for pharmaceutical quality control and research laboratories, combining precise measurements with guided workflows and flexible test management.

Overview and key capabilities

• Performs comprehensive manual 5-parameter tests: hardness (up to 500 N), thickness, width (for oblongs), diameter (for round tablets) or length (for oblongs), and weight (with optional connected balance).
• Top-mounted 7" touchscreen with TestAssist guides operators step-by-step, reducing training time and minimizing user error.
• Interchangeable magnetic inserts (flat / 1 / 2 / 3 mm groove radius) secure and align various tablet shapes; standard support for 1–30 mm tablets and optional breaking jaw for 30–60 mm tablets.
• Advanced test and user management: create, save, recall and manage products and methods; up to 100 methods and up to 100 samples per test; supports constant speed and constant force modes and flexible parameter settings.
• Integrated qualification and calibration workflows: on-screen guided qualification menu and optional AutoCal 2.0 electronic calibration (no measurement weights required) via USB.
• Smart enclosed collection container with lid sensor contains fragments and can automatically continue tests after lid closure; optional automatic continuation and pause settings.
• Seamless data handling: optional connection to external balances for automatic weight capture; compatibility with ERWEKA Export Manager for PDF/XML report export to lab networks.

TestAssist & Test Management details

• On-screen guided sequences for each test procedure and qualification steps.
• Quick direct measurements or comprehensive measurements using saved products and methods.
• Method and product lists with filtering, exporting and editing; up to 100 stored methods and up to 100 samples per test for reproducible workflows.
• User management with up to 100 users and configurable access rights.

Interchangeable Magnetic Inserts

• Four magnetic inserts (flat, 1 mm, 2 mm, 3 mm groove radii) for precise alignment of diverse tablet geometries.
• User-changeable breaking jaw option for larger tablets (30–60 mm).
