We understand the many challenges associated with thermocouple calibration work. That is precisely why we decided to introduce the ADT875-1210 and ADT878-1210 Thermocouple Calibration Furnaces.
With an unmatched stability, uniformity and an optional on-board process calibrator, calibrating thermocouples has never been easier. With two separate units to choose from, the ADT875-1210 and ADT878-1210 furnaces include a patented multi-zone temperature control which provides a never before seen, highly stable and uniform heat source to ensure you get the best possible results from a modest investment. With metallic interchangeable inserts, users have the flexibility needed to service a wide variety of UUT’s and the durability they have come to expect from Additel. The ADT875-1210 and ADT878-1210 can be purchased with or without our on-board process calibration electronics to provide flexibility for customers who are needing the best 1200°C heat source on the market.
If thermocouple calibration and/or verification work is part of your workload, you don’t want to miss out on this opportunity to save valuable time and money with these best in class furnaces from Additel.
Temperature Control
The Additel ADT875 and ADT878 Thermocouple Calibration Furnaces have been designed with a unique and innovative way of controlling temperature and temperature gradients. We like to call it “Advanced Adaptive Control”. This exciting new design feature incorporates our patent pending wind tunnel control technology with Additel’s impressive 3-zone temperature control to provide the very best uniformity and stability possible.
Each ADT875 and ADT878 is tested and calibrated in Additel’s accredited laboratory (Brea, CA) to ensure that each unit is ready to go when the customer opens the package. The included accredited calibration certificate provides data relating to accuracy, stability and uniformity to help provide even more confidence in the testing and calibration of each and every ADT875 and ADT878 Thermocouple Calibration Furnace.
Process Electronics
Both the ADT875 and ADT878 can be ordered with Additel's Process Calibrator(PC) option. The Process Calibrator Option combines the many features foundin a thermocouple readout device and process calibrator with the ADT875 andADT878 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 handy self-calibration feature!
