Additel ADT878-425 Reference Dry Well Calibrator
Overview
The ADT878-425 is the mid-range model of the Additel 878 reference dry well family, covering 33 to 425 °C at 23 °C ambient. Reference-level accuracy and stability, dual-zone control, set-point control by reference and the automated self-calibration routine keep the well traceable without manual recalculation of long-term drift.
A 6.5 in color touchscreen, Wi-Fi, Bluetooth, USB and RJ45 connectivity and an ISO 17025 accredited calibration with data are standard. The Process Calibrator option adds a reference PRT input, two UUT channels for mA, voltage, switch, RTD or thermocouple measurement, and a full HART communicator. This unit ships without an insert and is configured for 110 V power.
