The Yokogawa B9902AR is an authentic, high-precision disposable plotter pen engineered specifically for marine course recorders and Yokogawa industrial strip chart recorders. Designed to operate reliably under continuous maritime conditions, it produces clear, continuous purple trace lines without blotting, skipping, or ink feathering.

Utilizing quick-drying, fade-resistant ink, this recording pen provides accurate long-term physical logging of ship heading, rudder angle, and navigation track data. It is an essential replacement consumable for commercial vessel navigation bridges, gyro heading recorders, and engine control logging systems.

Key Features:
• Distinct Color Tracing: High-contrast purple ink allows effortless visual distinction on multi-pen bridge recorders.
• Maritime Vibration Resistance: Engineered to maintain steady line contact and uniform ink flow despite vessel motion and hull vibration.
• Quick Snap-In Mounting: Fast, tool-free replacement onto the recorder arm minimizes maintenance effort during watchkeeping.
• Factory-Sealed Freshness: Individually sealed packaging preserves ink quality and prevents premature drying prior to activation.
