Ships head is clearly read from a 120mm diameter rotating card marked in 1° increments with 5° and 10° divisions also defined. All 3 digit numbers (4mm height) are shown at 10° intervals and all scale markings are white on a black card background.
Variable intensity backlight illumination is controlled from a dimmer pot mounted on the instrument bezel to illuminate all card legends in red or green (installation selectable) for night viewing.
Unaffected by steel enclosures, the NT920AHR is particularly suitable for emergency steering position use in tiller flats etc.
