XNR-400B Melt Flow Rate tester (touch screen)

1、 Instrument Overview
This machine is suitable for testing engineering plastics such as polyethylene, polyarylsulfone, fluoroplastics, nylon, etc. with high melting temperatures, as well as plastics with low melting temperatures such as ethylene, polystyrene, polypropylene ABS resin, and polyoxymethylene resin.
2、 Instrument characteristics
Using advanced electronic measurement technology, the color touch screen displays the test results, and the output results of the micro printer have a compact and beautiful structure. The control system can measure and display temperature values in real time, and has functions such as upper limit temperature protection, constant temperature sound prompt, and recovery time prompt. By adopting advanced PID control technology and a high-speed and high-resolution sampling circuit, the machine has the following characteristics in constant temperature: fast heating speed and high precision of constant temperature. After filling, it can quickly return to a constant temperature state.
