Optimised for long-term reliability, accuracy, and ease of use, the Druck PTC255/PTC255i Multifunction Premium Temperature Calibrator functions as a dry block, liquid bath, infrared, and surface calibrator. It can be used to calibrate temperature measuring devices and temperature sensors, as well as verify their functionality. With a room temperature to 255°C (RT to 491°C) range and a large calibration volume/insert, the Druck PTC255/PTC255i can calibrate a wide variety of sensors and devices simultaneously. There are two versions of this multifunctional temperature calibrator: one with an integrated measuring instrument and one without. Please see the table below for further information.

SKU Integrated Measuring Instrument  Notes 
PTC-255 n/a
PTC-255i
  • Assumes the task of an external measuring instrument 
  • Shows the temperature directly on the calibrator display
  • Enables fully automatic calibration of two devices simultaneously
  • Simplifies your work process
  • Efficient 
  • Calibrate: Pt100, Pt500, and Pt1000 resistance thermometers (RTDs) in 2-, 3-, or 4-wire circuits; type K, J, N, E, R,T, B,S, L, and U thermocouples (TC), 0-20mA temperature transmitters with/without supply voltage; and temperature switches with normally open and normally closed contacts 

 

Offering four calibration functions and patented control technology that delivers the fastest stabilisation times on the market, the Druck PTC255/PTC255i Multifunction Premium Temperature Calibrator is a cost-effective and efficient solution to your calibration requirements. It offers time savings of up to 50% and can be used to calibrate temperature sensors/measuring devices to a resolution of 0.001°C/K, meeting the stringent requirements of the food and pharmaceutical industries. The Druck PTC255/PTC255i can be ordered with a stainless-steel housing suitable for use in these challenging environments.

All the relevant data (reference, target, and the temperature of the devices under test) is displayed on the clear, large, seven-inch touchscreen with multi-panel safety glass. The intuitive menu structure makes it quick and easy to enter the necessary inputs and switch between the calibration functions. The Druck PTC255/PTC255i Multifunction Premium Temperature Calibrator can be purchased with an optional camera, a feature which also adds to its convenience and ease of operation. The camera will capture an image of the temperature sensor’s/measuring device’s display. The data is then used to create a calibration certificate to which the captured images are attached. This allows you to carry out other tasks while the Druck PTC255/PTC255i Multifunction Premium Temperature Calibrator automatically conducts the calibration process.

Versatile, accurate, and simple to use, the Druck PTC255/PTC255i Multifunction Premium Temperature Calibrator is suitable for the most precise and demanding temperature calibration applications.
