Other tests
Measurement of Mass, Dimensions and Density : These are the most frequently done measurements in testing labs. They could be used as routine measurements for quality control or for checking of consistency or as essential parts of other physical tests.
Electrical Properties : Electrical properties of polymers, elastomers, composites and plastic films are very important to a wide range of industries like automotive, aerospace, building products, marine, packaging and consumer goods. Electrical tests, in general, are measurements of the resistivity, conductivity or charge storage either on the surface or through the material.

Magnetic property : Measurement of magnetic properties is very important, especially when magnetic particles are added into polymer to impart magnetic susceptibility.
Magnetic susceptibility Meter (MS3, Bartington) : The MS3 enables measurements up to 26 SI, with are solution up to 2x10-6 SI. It comprises a meter with a range of sensors and probes for measuring the magnetic susceptibility of many types of material including soils, rocks, powders and liquids. The system is suitable for use in the laboratory and in the field.

Measurement of Moisture content : Moisture affects the morphology and mechanical properties of polymers. Moisture content of compounding ingredients should be well within the specification, as higher moisture content may adversely affect the performance of the polymeric goods.
Moisture Content Analyzer : (MA 150, Sartorius) The MA150 infrared moisture analyzer features a compact design along with flexibility of use. Their program memory enable efficient moisture analysis even for a large number of different samples and is therefore optimally designed for use in inspection of incoming goods and quality assurance.
