Additel [ADT875PC-1210 Standard Thermocouple Calibration Furnaces With Process Calibration Option, 100°C to 1210°C, 220V. With two separate units to choose from, the Additel ADT875-1210 and ADT878-1210 furnaces include a patented multi-zone temperature control which provides a highly stable and uniform heat source to ensure you get the best possible results. With metallic interchangeable inserts, users have the flexibility and durability needed to service a wide variety of UUT's. Both the ADT875 & ADT878 can be ordered with Additel's Process Calibrator (PC) option. The Process Calibrator Option combines the many features found in a thermocouple readout device and process calibrator with the ADT875 & ADT878 Calibration Furnaces. This unique option includes Additel's patented Quick-Push connectors which accommodate virtually all TC connection types. The process option also includes the ability to measure a reference grade thermocouple and up to (4) under test channels. Channels 1 and 2 can measure mA, voltage, perform switch testing and source 24V DC. In addition to these measurement functions, the process option provides full documenting capability of creating tasks, saving "as found" and "as left" results and HART communications for simplified transmitter work. The snapshot feature allows users to capture all information displayed on the screen with a touch of the screen. This optional add-on allows for data logging of all channels using our auto step and a ramp functions. By utilizing the external reference option users can select to control to the furnace set point using an external control probe, which helps to reduce uncertainties. The external control probe feature also facilitates the self-calibration feature.
