Electromechanical universal testing machine (UTM)
max. 2 kN | Model 5948 Instron

The Model 5948 MicroTester offers solutions for industries faced with the challenges of testing small assemblies or miniature specimens by combining an ultra-high precision drive system with high-accuracy load measurement. The MicroTester has the ability to perform tension, compression, and low-cycle fatigue tests with a load force range of <2 mN up to 2 kN. Micro-position displacement control is obtained using a preloaded ballscrew drive system that is equipped with both a rotary encoder and a 20 nm resolution linear glass-scale encoder. The end result is a mechanical testing system that provides unparalleled control performance for short-displacement tests.
General Purpose Research
The Model 5948 MicroTester provides researchers with a precision instrument capable of performing numerous mechanical tests. For applications requiring precision control, high-load frame stiffness, high-drive system stiffness, and sensitive load measurement, the 5948 provides a superior platform for generating quality, reliable force-displacement data. Combined with Bluehill® Software, the possibilities are limitless.

Key Features

- Force range for wide range of specimen sizes: <2 mN (0.2 g, 0.0004 lbf) to 2 kN (200 kgf, 450 lbf)
- Open and unobstructed workspace accommodates odd-shaped components
- High-stiffness load frame for accurate and repeatable test conditions
- Position resolution for ultra-precise displacement control: 20 nm (0.8 µin)
- Electromechanical (non-hydraulic) drive system is clean and quiet, and vastly stiffer than electrodynamic systems for greater control and resolution during sensitive tests
