SZB-9 type automatic specific surface area measuring instrumentAccording to the requirements of the new standard CBT8074-2008, the company and the National Building Materials Research Institute of Cement and New Materials Institute of Equipment and Equipment Quality Supervision, Inspection and Testing Center developed a new SZB-9 type cement specific surface area automatic measuring instrument. The machine is controlled by a single-chip microcomputer and is operated with full touch keys to automatically control the entire measurement process. Automatically memorize the value of the instrument coefficient, directly display the specific surface area value after the measurement, and automatically memorize the measured specific surface area value while recording the experiment time.Technical Parameters:1. Power supply voltage: 220V ± 10%2. Timing range: 0.1 seconds-999 seconds3. Timing accuracy: <0.2 seconds4. Measurement accuracy: <1 ‰5. Temperature range: 8-34 ℃6. Specific surface area value S: 0.1-9999 cm² / g7. Scope of application: The scope specified in GB / T8074-2008
