  • Scanning Electron Microscopy

    SEM - Materials Evaluation and Engineering

    JEOL JSM-6610 LV LaboratoryScanning electron  microscopy (SEM) uses electrons for imaging to obtain higher magnifications and greater depth of field than light microscopes. The instruments at MEE are capable of variable-pressure, or low vacuum, SEM (VPSEM), as well as traditional high-vacuum conditions for sample observation. VPSEM is a specialized method using a variable-pressure sample chamber that allows direct evaluation of samples that are not readily examined with a traditional high-vacuum SEM. Nonconductive or vacuum sensitive samples that would typically require additional sample preparation can be directly analyzed in VPSEM without the need for additional sample preparation, such as carbon or metallic conductive coatings. This reduces both sample preparation time and distractions in microanalysis. Our laboratory also has a field emission SEM (FESEM) for critical high-magnification work and low-voltage (LVSEM) applications. Each instrument has a spacious sample chamber that can accommodate large and irregularly-shaped specimens and accessories for feature dimensional analysis and chemical microanalysis.

  • Surveyor Thickness Gauge

    Multigauge 5650 - Tritex

    The Multigauge 5650 Surveyor Thickness Gauge is a simple, robust ultrasonic thickness gauge designed specifically for ship and small craft surveyors, but can also be used in applications where different measurement modes are required. The user has a choice of Multiple Echo, Echo to Echo or Single Echo to cover all requirements. The gauge can be used for metal, GRP or plastic measurement and it automatically switches modes and settings depending on the type of probe fitted. The easy to use keypad on the Surveyor Thickness Gauge allows operator interface whilst the bright LCD display can be used in all light conditions. All probes have Intelligent Probe Recognition (IPR), which automatically adjusts settings in the gauge at the same time as transmitting recognition data the result is a perfectly matched probe and gauge for enhanced performance. Additionally, the Automatic Measurement Verification System (AMVS) used with multiple echo ensures only true measurements are displayed, even on the most heavily corroded metals.
