Description
The Druck PTC255 is a premium multifunction temperature calibrator designed for fast, accurate and reliable temperature calibration in laboratory and industrial environments. It combines four calibration methods in a single instrument—dry block, calibration bath, infrared thermometer calibration and surface sensor calibration—providing exceptional flexibility for a wide range of temperature calibration applications.
Featuring patented control technology, the PTC255 delivers some of the fastest stabilization times available, reducing calibration time by up to 50%. Its large 7-inch color touchscreen offers an intuitive interface for configuring tests, monitoring reference and target temperatures, and automatically generating calibration certificates.
The PTC255 supports simultaneous calibration of multiple sensors with its large calibration insert and is ideal for calibrating RTDs, thermocouples, infrared thermometers and surface temperature sensors. It also supports optional barcode scanner and camera accessories for streamlined device management and automated calibration workflows. The standard PTC255 is a temperature calibrator only; users requiring integrated electrical measurement should select the PTC255i model.
