LR-A001-D Fully Automatic Melt Flow Index Tester
3.Product advantage：
- Ø more paragraphs (2) temperature control method, two groups of platinum resistance sensor, two heating jacket separate temperature control, high accuracy intelligent PID control, ramp rate the heating speed is adjustable
- Ø resolution temperature was 0.1 ℃, the temperature uniformity of 0.2 ℃, the temperature fluctuation of not more than 0.5 ℃ within 24 hours, the displacement sensor resolution is 0.001 mm.
- Thermal protection device
- Ø hａnd automatic cutting material, can be arbitrary set blanking time (0 ~ 999), blanking times (0 ~ 999)
- Ø test can choose quality standard, or volume method, two test methods or simultaneously, and can melt density is calculated.Both methods are tested when the piston rod moves to a certain position.
- Ø stable internal temperature alarm prompts, and an increase of 240 seconds (GB3682 regulations) material preheat second countdown, after the end of the countdown, issued a prompt, can also set the American standard (ASTM) preheating time, etc.
- Ø built-in many plastic material melt index test conditions, convenient customer used to be obtained at any time, reduce the tedious work, and storing the last test conditions and results
- Built – in mini printer for easy printing test data
- Ø high precision touch screen controller, 7 inch touch screen, can be stored and print test conditions and data recently, test print menu Settings include test time (the default) system, operating personnel, material name, test method, test conditions (temperature, weight weight, blanking interval) data, test results, test results, the artificial judgement OK or NG, etc.,
- Ø reserved RS232 interface or USB interface to connect computers, can through the computer control instrument operation and to save test data transmission to the computer,
- Ø need weight load, are installed in screen equipment to choose corresponding weight and loading that no user manual loading or bolt type selection, reduce the workload.Test completion self – rising.
Test Methods:MFR +MVR Methods
