Yiwei Technology's rotorless vulcanizing instrument is a new generation, reliable, accurate, and intelligent rubber rheometer. To provide good data repeatability and reproducibility for formula and quality engineers, configurable automation accessories can be used to improve testing efficiency and reduce labor costs. MES interface can be provided to facilitate the construction of factory informationization standards. A set of software operation software connects multiple instruments.
Photovoltaic material vulcanizing instrumentEV-MDR precise PT100 platinum temperature measurement, microcomputer control integrated motherboard temperature control, ultra fast temperature return speed, stable temperature 7-inch color touch screen operation, can be used independently without a computer for automatic balancing, built-in weights, automatic calibration, reducing human operation errors. The internal structure is simple and durable, and the maintenance space is more spacious. Modular design makes maintenance simple, convenient, stable and reliable, and can be used continuously with dedicated operating software. The four column suspension structure design can be used for statistical management and analysis of data, and the DSP data acquisition system is stable.
