The Isotech Dual Heatpipe Furnace offers an innovative solution for high-precision temperature calibration, developed specifically for calibrating and maintaining ITS-90 fixed-point cells. Designed to calibrate thermometers with high precision without the need for complex adjustments, this advanced furnace delivers uniform temperatures over the full length of the fixed-point cell. With more than 35 years of experience and frequent use by national metrology institutes worldwide, Isotech is known for the reliability and precision of their equipment.
The Dual Heatpipe Furnace combines the advantages of traditional heat pipe furnaces with a unique second furnace system. This system allows users to condition thermometers both before and after calibration in a safe and controlled manner. The second oven provides controlled heating of thermometers, minimising the risk of thermal shock and contamination. This allows thermometers to be safely returned to room temperature after calibration.
The oven uses heat tubes that ensure virtually temperature-free temperature cycling. This is essential for maintaining accuracy when working with fixed-point cells such as indium, tin, zinc, aluminium, silver and copper. The temperature uniformity is less than 10 mK along the entire length of the cell, ensuring very stable and accurate calibrations. The plateau period can be adjusted and can last up to tens of hours, depending on user needs.
Functionalities
The user functionalities of the Dual Heatpipe Furnace focus on both simplicity and safety. The device is equipped with overtemperature protection that protects expensive equipment such as fixed-point cells and standard reference platinum thermometers (SPRTs). The oven is also equipped with a second, internal overtemperature protection for added safety. An integrated cooling coil in the lid can be connected to running water to control the temperature, helping to protect the laboratory from excessive heat exposure.
The Dual Heatpipe Furnace is equipped with convenient new features such as movable controllers, an SPRT mode and cable holders, which ensure an orderly working environment. The programmable cell melting and freezing functions make this device highly suitable for laboratories looking for a fully automatic calibration solution. The clear displays and intuitive controls make it easy to control the furnace and take accurate measurements.
With the Isotech Dual Heatpipe Furnace, you are investing in a reliable and proven temperature calibration solution. Whether you are working with industrial or scientific applications, this furnace offers the precision, safety and efficiency you need for accurate fixed-point calibrations.
