JB-B Series Impact Testing Machine

Introduction

JB-B serial Impact Testing Machine is mainly used to determine the anti-impact capability of metal materials under dynamic load. This machine can be operated semi-automatically. The pendulum of the machine can be raised or released automatically by button pressed. They have the features of easy operation, high efficiency, safe and reliable.

The machines are especially suitable for laboratory, metallurgy industry, machinery production, steel plant and other fields. JB-B series impact testers are strictly designed according to the standards ASTM E23, ISO148-2006.

Features

► Two Pendulums (big and small) and two scale reading for each testing machine which enlarge the test range of energy.
► Pendulum rising, impact, free releasing is realized as automatically by control remote.
► Safety pin guaranties the impact action.
► Protection shell avoids the hit and break sample splashing.
► Sample and support are easy centering.
► Electromagnetic clutch hold the rasing pendulum. Power sudden off still in safety.
