Additel ADT878 Reference Dry Well Calibrator

Overview

The Additel ADT878 is a reference-grade dry well calibrator designed for temperature measurement and control in laboratory and field environments. Available in three temperature ranges (-40 to 160°C, 33 to 425°C, and 33 to 700°C), the ADT878 combines high accuracy with advanced automation features. Each unit includes a large color touchscreen display, dual-zone control, and optional Process Calibrator functionality for measuring multiple sensors and HART transmitter configuration.
