High Temperature Calibration Furnace



EDL’s Furnace line was designed for accurate testing of both thermocouples and RTDs at high temperatures with extremely stable and uniform results.

SKU: FUR Category: Tags: ,


EDL’s FUR-1200 High Temperature Calibration Furnace is ideal for the testing and calibration of thermocouples and RTDs. Comparison calibrations are easily performed between 300 Ā°C and 1200 Ā°C (with intermittent operation up to 1250 Ā°C). The internal Inconel equalization block produces a highly stable and uniform temperature field ideal for high accuracy calibration, long-term drift tests, and temperature cycle tests. The block’s standard design is capable of accommodating up to 20 sensors and may be customized to meet your specific requirements.



EDL’s FUR-1500 Ultra High Temperature Calibration Furnace was designed for accurate testing of both thermocouples and RTDs. Calibrations between 300Ā Ā°C and 1500Ā Ā°C are easily, quickly and accurately achieved with this innovative split-tube, 3-zone furnace with Silicon Carbide elements. Engineered with unique features that make thermocouple calibrations both more efficient and more accurate, the FUR-1500 is specially designed to perform high accuracy calibrations as well as long term drift and temperature cycle tests. Highly stable and uniform temperature fields are accomplished with the use of an internal equalization block and a high purity ceramic liner over 5mm thick. This protective tube diffuses the element’s energy helping to create a more uniform and stable temperature field for the most accurate measurements.

The FUR-1500 is available with a test cycling option that allows the user to cycle their sensors through a temperature, time and dwell cycle. The cycle is accomplished by moving the sensors in and out of the hot-zone using a front mounted air cylinder. The process is controlled by an imbedded micro-controller that can be interfaced to the user’s computer for profile programming. This type of testing allows the user to see initial shifts that may occur due to thermal cycling. Sensors are subject to extreme temperature shifts during use, even when used in a non-static environment. Industrial laboratories have begun assessing the effects of cycling on their temperature sensors and our cycle test option on the FUR-1500 allows the user to test for and identify hysterisis.

All of EDL’s products are made in the USA. We guarantee the highest quality goods that are engineeredĀ and built by skilled craftsmen with ample experience in the temperature measurement and calibration field. SinceĀ 1943, EDL’s focus has been on achieving levels of accuracy that are unmatched by any other company. Let EDL take uncertainly out of your measurements, rely on EDL for all of your temperature and calibration needs.
