DRK208 touch color screen melt flow rate tester (hereinafter referred to as the measurement and control instrument) adopts the latest ARM embedded system, 800X480 large LCD touch control color display, amplifiers, A/D converters and other devices adopt the latest technology, with high precision , The characteristic of high resolution, simulating the microcomputer control interface, the operation is simple and convenient, and the test efficiency is greatly improved. Stable performance, complete functions, more reliable and safer. The melt flow rate meter is an instrument used to characterize the flow properties of thermoplastic polymers in a viscous state. It is used to determine the melt mass flow rate (MFR) and melt volume flow rate (MVR) of thermoplastic resins. It is widely used Used in plastic raw materials, plastic production, plastic products, petrochemical industries and other industries. Digital PID temperature control, temperature control is more accurate and faster; The displacement is measured by a digital encoder, with higher accuracy; The test automation program is high, which greatly improves the test success rate; After the test, the average, maximum, minimum, and standard deviation of the test results can be calculated in groups, which is convenient for customers to process the test data; Standards Compliant: 1. Technical indicators Displacement resolution: 0.001cm Timing accuracy: 0.01s LCD display life: about 100,000 hours The number of effective touches of the touch screen: about 50,000 times 2. Data storage: The system can store 511 sets of test data, which are recorded as batch numbers; Each group of tests can be carried out 10 tests, which is recorded as a number. 3. Types of tests available: (1) Method A: Mass flow rate (2) Method B: Volume flow rate 4. Implementation standards: GBT3682.1-2018 Plastic Thermoplastic melt mass flow rate (MFR) and melt volume flow rate (MVR) determination. Calibration: Before leaving the factory or after using the testing machine for a period of time, all indicators that have been verified to exceed the standard must be calibrated. In the <Main Test Interface>, touch the "Calibration" button, and the password input interface will pop up. Enter the password () to enter the <Calibration interface>. (Except for the legal metrology staff, do not enter the calibration state during the use of this system, otherwise the calibration coefficients will be modified at will, which will affect the test results.) In the <calibration interface>, the displacement sensor can be calibrated. 1. Arm length: displacement measurement arm length; 2. Encoder coefficient: 360 degrees divided by 4 times the number of encoder lines. 3. Temperature correction: Correct the measured temperature.
