ASTM D240 Auto-Calculating Microcomputer Oxygen Bomb Calorimeter SH500C
SH500C Automatic touch screen oil calorific value meter in accordance with GB/T 213-2008 and GB/T384.It is mainly composed of constant temperature calorimetry system and MCU embedded system. It is a highly automatic heat measurement instrument automatically controlled by the intelligent MCU embedded system and capable of data processing.The instrument is mainly used for the determination of the calorific value of combustible materials such as coal, petroleum, chemical industry, food and wood.
Main features
- The embedded system is composed of intelligent MCU, which has the advantages of simple structure, reliable performance and strong anti-interference ability.
- Adopt imported high-precision components to achieve high-precision temperature measurement.With the complete and unique water injection and drainage and calorimetry system of the instrument, the heat capacity of the system can be automatically calibrated, and the calculation program carefully compiled greatly improves the measurement accuracy.
- Adopt color touch screen display, full Chinese display, good user interface.Automatic control of measurement process.Print the analysis base shell, analysis base high, dry base high, analysis base low, receive low base calorific value, the result is clear and clear.
- Adoption of unique tracking and correction technology, so that the instrument on the environment requirements are relatively loose, improve the test accuracy, and ensure the stability of long time operation.
- The inner cylinder adopts electric stirring of sheet paddle;Adopt fuse type cotton thread ignition mode, high reliability, easy operation.
- The time temperature curve is drawn during the experiment, which is helpful to observe the experiment process.
- The operation is fully automated, the manual need to do is only weighing, loading and oxygenation, the instrument automatically complete quantitative water injection, automatic mixing, ignition, output printing results, drainage and other work.
- Single pump replacement injection and drainage, eliminate the original double pump model drainage pump easy to plug the problem, and no need to adjust the water injection time
