Name: Additel 875-1210 & 878-1210 Thermocouple Calibration Oven
SKU: 3239
Availability: InStock

With unparalleled stability, uniformity and an optional built-in process calibrator, calibrating thermocouples has never been easier. With a choice of two separate units, the Thermocouple Calibration Oven ADT875-1210 and ADT878-1210 feature patented multi-zone temperature control that provides a highly stable and uniform heat source.

This is unprecedented on the market and ensures that you get the best possible results with a modest investment. With metal interchangeable shaft sleeves, users have the flexibility needed to operate a wide range of UUTs and the durability one has come to expect from Additel. The ADT875-1210 and ADT878-1210 Thermocouple Calibration Oven can be purchased with or without our built-in process calibration electronics to provide flexibility for customers requiring the best 1200°C heat source on the market.

If calibration and/or verification of thermocouples are part of your operations, you don't want to miss this opportunity to save valuable time and money with these premium furnaces from Additel.

The Additel ADT875 and ADT878 thermocouple calibration ovens are designed with a unique and innovative way of controlling temperature and temperature gradients. We call it “Advanced Adaptive Control”. This exciting new design incorporates our wind tunnel control technology (patent pending) with Additel's impressive 3-zone temperature control for the best possible uniformity and stability.

Each ADT875 and ADT878 is tested and calibrated in Additel's accredited laboratory (Brea, CA) to ensure that each unit is ready for use when the customer opens the package. The included accredited calibration certificate contains accuracy, stability and uniformity data, providing further confidence in the testing and calibration of each ADT875 and ADT878 thermocouple calibration furnace.
