1. The furnace body heating adopts ring arrangement to reduce interference; 2. The weighing sensor made of precious metal nickel-chromium alloy has the advantages of high temperature resistance, oxidation resistance and corrosion resistance;
3. The power supply, circulation heat dissipation part and the host are separated to reduce the impact of heat and vibration on the micro-heat sensor;
4. Adopt the upper electric lifting structure, easy to install and operate;
5. Water bath constant temperature device is used to isolate the thermal influence of heating furnace body on the chassis and micro-thermobalance.

Model

Vacuum atmosphere vertical quenching furnace NBD-LT1500/1700-80TI

Main function

1. In the process of heating, constant temperature or cooling, it can automatically record the change curve of sample temperature, vacuum degree, gas flow rate and time;
2. Measure and study the following properties of materials: thermal stability, adsorption and desorption, quantitative analysis of components, moisture and volatiles, decomposition process, oxidation and reduction, effects of additives and fillers, reaction kinetics.

Cautions

1. When the furnace temperature of the equipment is ≥300℃, do not open the furnace to avoid damage;
2. When the equipment is used, the pressure in the furnace tube shall not exceed 0.125MPa (absolute pressure) to prevent damage to the equipment caused by excessive pressure;
3. When used under vacuum (10 to the minus 3 Pa), the use temperature of the equipment shall not exceed 800℃.

Service

1 year warranty with lifetime support (warranty does not cover consumable components such as furnace tubes and seals).
