Additel ADT878PC-425-C-220V Dry Well + Process Calibrator 425C

Additel ADT878PC-425-C-220V Dry Well + Process Calibrator 425C

Overview

The ADT878PC-425 is an Additel 878 Reference Dry Well Calibrator in the 33 °C to 425 °C range, fitted with the Process Calibrator (PC) option. It combines a dual-zone temperature source with a two-channel readout for RTDs and thermocouples, a reference PRT input and a 6.5 in color touchscreen. The PC option adds voltage and current measurement, a 24 V output and a HART communicator function.

Features

• Dual-zone temperature control with a 6.5 in (165 mm) color touchscreen
• Setpoint control by internal or external reference sensor
• Self-calibration of the internal control sensor against the external reference
• Two RTD channels and one thermocouple channel, plus a 4-wire reference PRT input (ITS-90, CVD, IEC-751)
• Quick-Push connectors and 6-pin Lemo smart connector for the reference PRT
• HART communicator to read, configure and calibrate HART devices
• Documentation of up to 1,000 tasks with as-found and as-left results, plus data logging with auto step and ramp
• USB A, USB B, RJ45, Wi-Fi and Bluetooth communication

Applications

Stable heat source for calibrating temperature sensors such as RTDs and thermocouples, and for configuring and calibrating HART transmitters.
