The Additel ADT875-155 Dry Well Calibrator is a portable, rugged, and high-performance solution for precise temperature calibration in both laboratory and field environments. With a temperature range from –40 °C to 155 °C, this dry block calibrator delivers exceptional accuracy, stability, and uniformity, ensuring reliable calibration of RTDs, thermocouples, transmitters, switches, and PRTs.
Equipped with dual-zone control and a 6.5-inch colour touchscreen display, the ADT875-155 combines ease of use with fast heating and cooling performance. For enhanced versatility, the optional Process Calibrator (PC) model integrates a three-channel documenting process calibrator with support for HART communication, multi-channel measurement (RTDs, TCs, mA, voltage, switches), loop power, and data logging.
For specialised applications, Additel also offers the Choose Your Own Range (CYOR) option. This feature lets users define custom upper and lower limits within the –40 °C to 155 °C span, with the calibrator optimised for maximum accuracy in that range.
