HRZ-400C weight electric loading melt index meter

Weight electric loading melt index meter

model:HRZ-400C

1、 Product Introduction:

Weight electric loading melt index meterIt is a high-precision melt flow rate meter used to measure the MFR/MVR values of various plastics and resins in a viscous flow state through a certain temperature and load. It is suitable for engineering plastics such as polycarbonate, polyarylsulfone, fluoroplastics, nylon, etc. with high melting temperatures, as well as for testing plastics with lower melting temperatures such as polyethylene (PE), polystyrene (PS), polypropylene (PP), ABS resin, polyoxymethylene (POM), polycarbonate (PC) resin, etc. It is widely used in plastic production, plastic products, petrochemicals and other industries, as well as related universities, research units and inspection departments.

3： Product advantages:

• Multi stage (3-stage) temperature control method, 3 sets of platinum resistance sensors, 3 copper heating sleeves for individual temperature control, high-precision intelligent PID regulation, adjustable heating slope or heating speed
• The temperature resolution is 0.1 ℃, and the temperature fluctuation within 24 hours does not exceed 0.5 ℃. The displacement sensor resolution is 0.001mm.
• Temperature over temperature protection device
• Hand automatic cutting integrated, can set cutting time (0~999) and cutting frequency (0~999) arbitrarily
• During testing, the quality method, volume method, or both testing methods can be selected, and the flow rate ratio can be calculated. Both methods start testing when the piston rod moves to a certain position.
• A 240 second (GB3682 standard) material preheating countdown can be set. After the countdown is over, the weight will automatically load and start cutting automatically when it reaches the specified range. Preheating times such as ASTM can also be set.
• Built in multiple plastic material melt index testing conditions, convenient for customers to access and use at any time, reducing tedious workload, and storing the testing conditions and results for the next test
• Built in micro printer for easy printing of test data
• High precision touch screen controller, 7-inch touch screen, can store and print near test conditions and data. The test printing menu settings include test time (system default), material name, test conditions (temperature, weight of weights, cutting time interval), and test result data.
• Reserved RS232 interface or USB interface for connecting to a computer, which can be used to control instrument operation and transfer and save test data to the computer,

Placing weights on the weight holder in advance can achieve electric loading and unloading, reducing manual operation.
