Four-Function Tablet Tester

Introduction

The Four-Function Tablet Tester is a precision instrument designed for comprehensive tablet quality control. It measures hardness, thickness, diameter, and weight in a single operation—ensuring compliance with pharmacopeial standards and consistency in pharmaceutical and nutraceutical manufacturing. This device is vital for accurate, efficient, and automated testing in both QC and R&D environments.

What Is Four-Function Tablet Tester?

A Four-Function Tablet Tester is a compact, automated device that assesses four key physical parameters of tablets—hardness, thickness, diameter (or length/width for oblong forms), and weight. Designed to meet USP, EP, and FDA guidelines, it ensures each batch meets critical quality specifications. Combining multiple tests in one unit improves data reliability, reduces handling time, and minimizes human error.
