Electric melt index meter

1、 Product Introduction:

This model is high-precisionElectric melt index meterA measuring instrument is used to determine the MFR/MVR value of various plastics and resins in a viscous flow state through a certain temperature and load, passing through a standard die melt flow rate every 10 minutes. 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 relevant universities, research units and inspection departments.

3： Product advantages:

Multi stage (5-stage) temperature control method, 5 sets of platinum resistance sensors, 5 heating sleeves for individual temperature control, high-precision intelligent PID regulation, adjustable heating slope or heating speed

The temperature resolution is 0.1 ℃, the temperature uniformity is 0.2 ℃, 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

Built in temperature stability alert and added 240 seconds (GB3682 standard) material preheating second countdown. After the countdown ends, a prompt sound will be emitted, and preheating times such as American standard (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 last testing conditions and results

Built in micro printer for easy printing of test data

High precision touch screen controller, 4.3-inch touch screen, can store and print the latest test conditions and data. The test print menu settings include test time (system default), operator, material name, test method, test conditions (temperature, weight of weights, cutting time interval), test result data, and manual judgment of test results as OK or NG

Reserved RS232 interface or USB interface for connecting to a computer, which can control instrument operation and transfer and save test data to the computer through computer control

It can be manually loaded with weights or driven by a stepper motor to rotate the ball screw to achieve automatic control of the top loading weight's rise or fall
