Thermocouple calibration work can be challenging. Here at Additel, we understand the difficulties of this type of work. Our new ADT850 Laboratory Thermocouple Calibration Furnace is packed with features and a performance you will not find anywhere else. The ADT850 horizontal furnace covers a range of 300 to 1200°C and 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 noble and base metal thermocouples with the lowest possible uncertainties. Additel’s ADT850 is the most accurate, 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.

The ADT850 also includes a sliding probe holder labeled with measurement gradients to help safely insert standard and UUT probes to correct depths. The advanced probe holder design includes a clamp to securely hold the test probe in place at all times.

Both alumina and metal inserts are available to help provide support and mitigate cross contamination for both metal and ceramic style probes. The ADT850 Laboratory Thermocouple Calibration Furnace can also be used without an insert to accommodate larger probes and to allow for simultaneous testing of a large quantity of test probes.
