JYW-300 type computer automatic constant stress testing machine price Manufacturers and other models

Functional use of the testing machine is mainly used for compressive strength test brick, stone, concrete and other building materials, mechanical testing can also be used other materials. This machine uses hydraulic loading, electronic measuring, with a load figures, loading rate shows maximum load to maintain, as well as overload protection and power data retention capabilities. A special test equipment, use of the machine for cement mechanical properties test and analyze research to fully meet GB / T 17617 "cement glue sand strength test method (ISO method)" requirements, are widely used in the construction industry and cement production enterprises. Second, the main function 1, automatic control measurement, data acquisition and processing, drawing and print test curve and test reports. 2, between the measurement and control system and a computer via RS232 communication, repair or replacement is very convenient. 3, test force resolution of 1/60000. 4. Control system software can work under Windows98 / 2000 / XP / NT Chinese operating system. 5, the use of digital electro-hydraulic proportional valve as the control actuator, anti-pollution ability, can achieve long-term trouble-free operation.
