MFR MVR Melt Flow Index Test Machine

Product Character:

1.More paragraphs (3) temperature control method, three groups of platinum resistance sensor, the three heating jacket separate temperature control, high accuracy intelligent PID control, ramp rate the heating speed is adjustable

2.Resolution temperature was 0.1 ℃, the temperature fluctuation of not more than 0.5 ℃ within 24 hours, the displacement sensor resolution is 0.001 mm.

Temperature and temperature protection device

3.Hand automatic cutting material, can be arbitrary set blanking time (0 ~ 999), blanking times (0 ~ 999)

4.Test can choose quality standard, or volume method, two test methods or simultaneously, and can calculate flow rate ratio.Both methods start testing when the piston rod moves to a certain location.

5.Can be set up in 240 seconds (GB3682 regulations) material preheat second countdown, after the end of the countdown, farmar automatically loaded, loaded to interval start automatic cutting, can also set the American standard (ASTM) preheating time, etc.

6.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

The internal microtyping machine is convenient for printing and testing data

7.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), the material name, test conditions (temperature, weight weight, blanking intervals), test results data.

8.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,

9.Can manually loading weight or by stepping motor drives the ball screw rotation in order to achieve the purpose of automatic control at the top of the load weight increase or decrease
