Excellent Linearity and Repeatability

Powered by Yokogawa’s proprietary sensing technology — combining a silicon resonant sensor with precision needle-valve flow control — the MC300 delivers an output relative accuracy of ±0.04% with one-year guaranteed long-term stability.
Extremely low hysteresis, excellent linearity, and high repeatability ensure stable, reliable pressure control over extended operating periods.

High-Speed, Smooth Pressurization

The MC300 mitigates the risk of overpressure at the device under test caused by rapid pressurization through smooth flow regulation using precision needle-valve control. Even as the setpoint is approached, it maintains fine pressure control to minimize overshoot and achieves a response time of less than 5 seconds.

Precise Needle Valve Control

The MC300 uses a needle valve servo mechanism in its pressure control section, adjusting airflow through the needle position to regulate output pressure. Unlike solenoid valve systems that rely on rapid open/close operations, the needle valve enables continuous, smooth movement. This design delivers stable pressurization and depressurization with minimal wear, ensuring long-term reliable operation
