FLUKE CALIBRATION TOOLS
Fluke Calibration Tools are used to ensure precision and accuracy across a wide range of industries. Fluke offers a comprehensive array of top-tier calibration tools to calibrate in many different disciplines offering precision instrument calibration and metrology hardware and software for electrical, temperature, pressure, flow, and RF measurements. Use these top-of-the-line devices to compare and adjust measuring devices to ensure they operate within their specified limits. Calibration instruments and software from Fluke Calibration are found in calibration facilities around the world, including National Metrology Institutes, that demand the highest levels of performance and reliability for their calibration equipment, backed by state-of-the-art metrology and uncompromising support.
Temperature Calibration Thermometers are typically calibrated by placing them in a stable temperature environment (heat source) and comparing their output to that of a calibrated reference thermometer or standard thermometer. Fluke Calibration provides three general categories of heat sources: industrial heat sources (dry-well calibrators, portable calibration baths, Micro-Baths, etc.) for field use; fluid baths and thermocouple furnaces for laboratory use; and fixed-point cells for primary calibrations. Fluke Calibration also offers a variety of reference thermometers, including SPRTs, and thermometer readout instruments. In addition, Fluke Calibration provides laboratory and field solutions for calibrating the electronics used in temperature measurement circuits. Electrical Calibration Electrical calibration involves the use of precise devices that evaluate the performance of key properties for other devices called devices under test (DUTs). Because these precise devices have thoroughly known performance characteristics compared to the DUT, performance evaluation and/or calibration adjustment of the DUT to identify or minimize errors is possible. Typically, the performance of such precision devices should be four or more times better than the DUT. These precision devices fall into two broad categories. Electrical signal sources are often referred to as either calibrators or standards. Precision measurement devices are often classified as reference digital multimeters, measurement standards, or ratio bridges.
Pressure Calibration
The comparison process can be performed in a chain from the highest level of fundamental pressure realisation down to everyday pressure measurement devices, such as analog gauges, transducers and transmitters, to ensure that pressure measurements are accurate and comply with accepted or mandated standards. The test fluid inside a pressure calibration system may be liquid or gas depending on the application. In general, gas (usually compressed nitrogen or air) is used for cleanliness and precision at lower pressures, and liquids (usually oil or water) are often used for safety, leak integrity, and ease of pressure generation at higher pressures above 7 MPa to 40 MPa (1,000 psi to 6,000 psi). There is a great deal of overlap in the actual ranges for which liquid or gas may be used practically, as reflected in the range of Fluke Calibration instruments that are specialised for each type of test fluid.
