Insulation Resistance Tester
The high temperature insulation resistance tester uses the parallel plate method design principle to measure. Using a unique resistance test system, the anti-interference ability of the fixture is improved, the repeatability and stability are better, and the accuracy is greatly improved. It can be used for product testing and research on the electrical properties of new materials.
The high-temperature insulation resistance tester(Infrared reflector furnace) is designed and developed in compliance with the standard "GB/T 10518-2006 Test Method for Resistance and Resistivity of Insulating Materials at High Temperature" and refers to the American ASTM standard. A number of safety designs have been made for high-temperature insulation resistance testers to ensure the safety of the test process under abnormal conditions such as over-voltage, over-current, over-temperature, etc.; the data storage mechanism ensures the safety of the test process when encountering computer abnormalities or instantaneous power outages. , the data can be saved in the controller without losing the test data, and the original test data can be restored after the equipment is restarted.

Heating method
At present, most domestic high-temperature heating methods are tubular furnaces or muffle furnaces. The main principle is to heat the furnace body with heating wires or silicon carbon rods. The heating and cooling processes are slow and inefficient. It is also impossible to achieve high-precision measurement of temperature, and there is also unevenness in the heating area. After years of research, Dexinmag Instruments has developed a paraboloid that can achieve high precision and high reflectivity, which is configured with a high-quality heating source to achieve high-speed heating. It has good temperature distribution during high-speed cooling. It can realize wide uniform heating zone, high-speed heating and high-speed cooling, and use quartz tube to protect the heated sample without atmospheric pollution. Can be heated in high vacuum and high purity gas. The equipment can be composed of a uniform high-speed heating furnace, a temperature slope furnace, and a stage heating furnace.
It improves heating test capabilities. Compared with resistance furnaces and other furnaces, the infrared reverberatory furnace saves the heating time, holding time and the time required for natural cooling to room temperature. The set temperature value can also be rewritten during the test. In every aspect, it saves experiment time and increases experiment speed.
Compared with high-frequency furnaces, there are no special installation conditions and requirements for heating samples. Like a resistance furnace, it is easy to install and has a cooling system that is safe and reliable. To improve the work efficiency of test personnel and realize a new temperature control operation!
High-speed heating and cooling methods
High-energy infrared lamps and gold-coated reflections allow high-speed heating to high temperatures. At the same time, the furnace body can be equipped with a water cooling system and a gas cooling device can be added to achieve rapid cooling.
Temperature control
Through the combination of infrared gold-plated focusing furnace and temperature controller, the temperature of the sample can be controlled (much better than ordinary heating methods). Additionally, the cooling rate and holding at any temperature provide high accuracy.
Heating and cooling in different environments
Heating/cooling can be used in vacuum, atmosphere environment, low temperature (high-purity inert gas, static or flowing), is simple to operate, and is made of quartz glass. Infrared light can be delivered to heating/cooling chambers.
Operational software
The software platform of the test system is developed using the labview system, which meets the various testing requirements of functional materials. It has strong stability and operational safety, and has the function of saving power-off data, and image data can also be saved and restored. Compatible with XP, win7, win10 and other systems.
