Used in cryogenics, chemical, pharmaceutical, food, machinery, and industrial laboratories
Ideal for portable, ultra-low temperature verification in demanding environments
A dry-block calibrator, also known as a dry-well calibrator, is a device used to calibrate temperature measurement instruments such as thermocouples, thermometers, thermistors, and resistance temperature detectors (RTDs). Unlike other calibration methods that might use liquid baths, dry-block calibrators provide a stable and uniform temperature source in a dry environment.
Heating/Cooling: The dry-block calibrator heats or cools a metal block to a precise temperature.
Insertion: The block has pre-drilled holes where temperature sensors or probes are inserted.
Stabilization: The calibrator stabilizes at the set temperature to ensure uniform heat distribution.
Measurement: The readings from the sensors are compared to the calibrator’s displayed temperature, and any discrepancies are noted and adjusted.
Dry-block calibrators are widely used in industries where precise temperature control is crucial, such as:
Pharmaceuticals: Ensuring medications are stored at correct temperatures.
Food and Beverage: Maintaining product quality and safety.
Manufacturing: Ensuring machinery and equipment function properly.
All orders, wherever possible are shipped the same day within the UK as long as it is received before 1 pm.
