Thermocouple calibration work can be challenging. Here at Additel, we understand the difficulties of this type of work. Traditional furnace designs require several individual devices to meet industry standards for various calibration applications. To address this costly reality, Additel has created a multi-purpose furnace to help save time, money and space in your calibration facility. Our new ADT850 Laboratory Thermocouple Calibration Furnace is like having three separate furnaces is one. Users can select optimized settings for shorter probes, longer probes and even annealing purposes. The ADT850 horizontal furnace can be used in (9) different modes/configurations to help meet even the most challenging calibration requirements and standards. Additel’s 850 furnace is packed with many additional features and a performance you will not find anywhere else. The ADT850 is commonly used in a multitude of industries such as energy, calibration laboratories, aerospace and metallurgy to name a few. It is generally used by primary and secondary calibration laboratories to calibrate various length noble and base metal thermocouples with the lowest possible uncertainties. Additel’s ADT850 is the most stable and versatile furnace available!

With our customer’s needs in mind, we have designed our all new ADT850 Laboratory Thermocouple Calibration Furnace with a modern look and feel. Users will experience that same easy to use menu structure and touchscreen interface that they have become accustom too when using genuine Additel products. The display pivots and tilts so users can customize the product to fit their needs.

With an unmatched flexibility, the ADT850 provides calibration and annealing support for a wide variety of thermocouple types and lengths. The unique selectable “mode of operation” integrated into the touchscreen interface allows users to select from (9) different modes, accounting for immersion depths from 200 mm to 370 mm. This coupled with the variety of insert types to accommodate reliable and repeatable measurements for both metal and ceramic style probes, gives users the flexibility to easily calibrate a wide variety of thermocouple sizes and quantities. These groundbreaking features make the ADT850 Laboratory Thermocouple Calibration furnace the most versatile and cost saving full sized thermocouple calibration furnace on the market.
