Thermocouple calibration work can be challenging. Here at Additel, we understand the difculties 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 nd 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!

Industrial Design

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 t 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.

With an unmatched exibility, 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 exibility 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.
