VET-003 is a split vacuum pre-pumping system customized for compact production lines. Through the "control box - host split layout + universal pump interface + Pirani high-precision sensor", it breaks through the triple limitations of space, adaptation and accuracy: the control box is reduced by 30% and supports 10-meter remote deployment; it is compatible with rotary vane/vortex/diaphragm pumps; 2.0Pa extreme vacuum + 0.1Pa fluctuation monitoring, covering refrigeration commercial inspection, vacuum coating, laboratory calibration and other scenarios, and complies with ISO 21511 (sensor accuracy) and IEC 60529 (IP54 protection) standards.
