Mainly used in laboratories in industries such as power, metallurgy, petroleum, chemical, and measurement systems. Used for verifying pressure (differential pressure) transmitters, precision pressure gauges, general pressure gauges, pressure sensors, pressure switches, and other pressure instruments and meters. Product features: External SEED-1 quick connector, easy to tighten by hand to reach 60MPa or 100MPa. The high-tech products of intelligent control technology, combined with computer software technology and pressure calibration industry. Fully automate the calibration process of pressure transmitters and pressure switches, and combine software to automatically perform a large amount of tedious pressure control, data recording, measurement, and filing work. Adopting built-in pressure source preloading and advanced pressure control algorithm, the pressure stability speed is fast. It has a pressure alarm function to protect the tested meter. When the pressure exceeds the range, it stops pressurizing and prompts an alarm signal. Large LCD touch screen, with a beautiful and elegant operating interface. Small in size, lightweight, and easy to move. Communicate with a laptop through a serial port to achieve voltage control, save calibration data, and print certificates. Using optional external modules as standards and separating the measuring part from the platform for easy inspection.
