The Additel ADT875-350 Dry Well Calibrator is a portable, rugged, and high-performance tool designed for temperature calibration in both field and laboratory environments. With a temperature range of 33 °C to 350 °C, this dry block calibrator delivers exceptional stability, accuracy, and uniformity, ensuring precise calibration of RTDs, thermocouples, transmitters, switches, and PRTs.
Equipped with dual-zone control and a 6.5-inch colour touchscreen display, the ADT875-350 offers fast heating and cooling, intuitive operation, and reliable performance. For added functionality, the optional Process Calibrator (PC) model integrates a full three-channel documenting process calibrator with support for HART communication, mA and voltage measurement, loop power, RTD and TC inputs, and switch testing.
Additel also offers the Choose Your Own Range (CYOR) option, enabling users to define custom upper and lower temperature limits within the 33 °C to 350 °C span. Each unit is then calibrated and optimised for maximum accuracy in the selected range.
