Handheld and dry block calibrators for industrial temperature calibration

Industrial temperature calibrators are critical in many industrial processes. A temperature calibrator is used to correct inaccuracies in the thermometers and temperature sensors used for these processes. A temperature source with a calibrated reference sensor is required to provide a complete and meaningful calibration. Fluke Calibration provides a wide range of industrial and field temperature calibrators including: Metrology Wells, Field Metrology Wells, field dry-well calibrators, handheld dry-block calibrators, Micro-Baths, infrared calibrators, and thermocouple furnaces.

    Handheld and dry block calibrators frequently asked questions

    What is the use of a handheld calibrator?

    Handheld calibrators are portable temperature calibration tools designed for convenience and efficiency in the field. They are used to verify and adjust the accuracy of temperature sensors and thermometers in various applications, such as ensuring precise temperatures in manufacturing, maintaining accurate readings in HVAC/R systems, calibrating vehicle sensors, and verifying temperature accuracy in food processing. Handheld calibrators are compact, lightweight, and durable, making them ideal for field use, and they offer fast response times and wide temperature ranges to meet diverse needs.

    What is dry block calibration?

    Dry-block calibration is a highly accurate temperature calibration method that uses a dry-block calibrator to provide a stable and uniform temperature source. These calibrators have a metal block with precision-drilled holes for inserting temperature sensors or thermometers.

    One of the primary advantages of dry-block calibrators is that they do not require liquids, which can be expensive to maintain/replenish, sometimes hazardous, and can limit the device's portability. This makes them a more convenient and safer option compared to liquid-based calibration methods. However, it's important to note that dry wells are more limited in the types of probes they can accommodate, generally accepting only cylindrical probes of specified diameters.

    Dry block calibration is essential in various industries, such as laboratory settings, pharmaceutical manufacturing, aerospace, and metrology, where high accuracy and precision are critical. Dry block calibrators offer excellent temperature stability, uniformity, and wide temperature ranges to accommodate various sensor types and sizes.
