The JLN-205MK2 is a stable and highly accurate measurement tool to ensure stable speed data utilizing high frequencies ultrasonic waves.
Dual LED backlight
The unit incorporates many display modes readily available on a highly visible 4.5-inch LCD display. Besides the display being fully dimmable and having backlit keys, it features dual LED backlight (white and orange), making it easy to operate in various light settings on the bridge.
Multiple display modes are available from the menu with main data displayed in large characters for easy reading. You can easily switch at your own convenience, particularly useful when a situation requires specific information.
The transducer is compact and constructed of light weight moulded rubber, to minimize the effects on aeration, which allows stable and accurate operation.
Using an optional gate valve transducer allows for long-term cost saving and easy maintenance as dry docking is not necessary.
An ultrasonic beam is transmitted in fore and aft directions. At the same time, the hull motions such as rolling and pitching are detected and removed by simply measuring the difference of the Doppler shift reception signal, ensuring accurate and stable speed data, even in the roughest conditions.
