Force testing machine PMT-B

automaticcomputer-controlledfor medical packaging

Introduction
PMT-B ampoule breaking force tester is a laboratory instrument for measuring the breaking/opening force of ampoules and similar tubular containers. Designed to comply with GB2637 and YBB00332002 standards, it uses an imported high‑precision force sensor and stepless speed regulation. The tester is supplied with five interchangeable fixtures for 1 ml, 2 ml, 5 ml, 10 ml and 20 ml ampoules, a protective cover and an automatic discharge structure for easy collection of damaged samples.

Applications
Widely used in pharmaceutical testing laboratories, pharmaceutical packaging material manufacturers, drug manufacturers, medical device makers and cosmetic companies for quality control of ampoules and small tubular containers.

Features

• Microcomputer control with open architecture and user-friendly human–machine interface tailored for laboratory workflows.
• Multiple selectable test modes (fixed force increase, positioning, displacement) for flexible test protocols.
• Precision screw drive and stainless steel guide rails for smooth, repeatable motion.
• Imported high‑precision force sensor with measurement accuracy Level 0.5 and 0.01 N resolution.
• Precision differential motor drive for stable transmission, low noise and accurate positioning.
• Large color display capable of showing curves and test data with built‑in automatic measurement and basic statistical processing.
• High‑speed micro printer for fast, low‑noise hardcopy output; easy paper roll replacement.
• Built‑in calibration routine to simplify verification by calibration departments or third parties.
• Option to connect to PC software for bidirectional operation and data management.
