Overview
The BZH-2.5-12 ash determination muffle furnace is a BOZHEN brand equipment specially designed for the determination of ash in petroleum products and plastic products, manufactured according to GB/T2433 standards. The device uses ashless filter paper as the ignition core, the sample is burned in a suitable container until carbonaceous residue, and then heated at a high temperature of 775 ° C -900 ° C to ash, and finally chilled down and weighed.
Features
1. The temperature controller adopts intelligent digital temperature controller, with professional PID control mode, double-row digital display microcomputer temperature control, with over-temperature alarm function and timing function, accurate and reliable temperature control.
2. Independent temperature limit alarm system, which automatically interrupts when the temperature exceeds the limit to ensure the safety of the experiment.
3. The configuration function can be added according to the customer's experimental requirements, and the program temperature control, fast gray and slow gray modes are supported. Users can modify the temperature and time of each heating section of ash and volatile matter by themselves.
Principle
The muffle furnace through the ashless filter paper as the ignition core, ignite the sample combustion to carbonaceous residue, and then 775 ℃ -900 ℃ high temperature furnace heating carbonaceous residue into ash, and finally chilled down and weighed to complete the determination process.
Applications
Petroleum products, plastic products
Steps
1, the use of ashless filter paper as the ignition core, ignite the sample in a suitable container combustion to carbon residue.
2, the carbonaceous residue in 775 ℃ -900 ℃ high temperature furnace heating into ash.
3, chill down and weigh the ash.
Notice
• The equipment has an over-temperature alarm function, which will automatically interrupt if the temperature exceeds the limit to ensure the safety of the experiment.
• The program temperature control, fast gray or slow gray mode can be configured according to the experimental requirements, and the user can adjust the temperature and time of the heating section by himself.
• Check the Thermocouple and terminal position before use to ensure correct connection.
• Pay attention to the high temperature of the furnace body and wear protective equipment during operation.
