design and manufacture instruments for the analysis of metals using ultrasonics. The range of instruments include on-line and laboratory versions for the analysis of Stainless Steels, Carbon Steels, Aluminium, Copper and Copper alloys.
Oxford Measurements
have installed instruments in Europe, USA, and Japan for measurement of Grain Size, Grain Uniformity and Recrystalisation of metals.

also design custom instruments for the measurement of particular mechanical properties for a special production requirement.

Advantages of On-Line Instruments for Continuous Annealing

Improved Quality Control

• very accurate and repeatable grain size measurement
• detection of non-recrystalised material with alarm if not fully annealed
• continuous measurement and recording of grain size along the entire coil length

  Improved Productivity

• automatic grain size measurement without sampling or laboratory analysis
• continuous measurement allows dynamic strip speed control for maximum productivity

  Improved Stock Control

• stock coils can be graded according to specification
• a coil or length of coil outside of specification can be located
• grain size data for every coil can be stored on stock control computer

Advantages of Laboratory Instruments

Improved Quality Control

• very accurate and repeatable grain size measurement
• detection of non-recrystalised material with alarm if not fully annealed

  Improved Productivity

• no sample preparation required
• no special operator training or skills necessary
• instrument may be located in the factory or laboratory
• fast measurement time - a sample may be measured in 10 seconds
