Description
Verified Maritime OEM
The Daiko Keiki DCL-40 is a marine mechanical clinometer engineered for direct wheelhouse bulkhead mounting, providing instantaneous, non-powered heel and list monitoring across a ±40° scale. Featuring a heavy-gauge cast marine alloy housing, high-contrast engraved dial with 1° graduations, and a precision viscous-damped indicator needle, the DCL-40 delivers flawless operational reliability during heavy seas and total blackout conditions. Manufactured in Japan to JIS F7001 standards, it is widely utilized on commercial cargo ships, workboats, and fishing vessels. In stock and supplied with class inspection certification by Seanav Marine, Dubai Maritime City.
Product Overview & Engineering Integrity
Manufactured by Daiko Keiki Seisakusho Co., Ltd. (Japan), the DCL-40 clinometer serves as an indispensable visual safety reference on the bridge. Designed for permanent vertical bulkhead installation perpendicular to the ship’s centerline, the DCL-40 indicates heel angle to port and starboard with zero electrical power dependency. Its counterbalanced pendulum is submerged in a specialized damping medium that filters out high-frequency engine vibration and hull shocks, presenting clear, steady readings to navigating officers and marine pilots.
As the trusted marine navigation equipment distributor based in Dubai Maritime City (UAE), Seanav Marine guarantees authentic manufacturer provenance from Daiko Keiki Seisakusho Co., Ltd. (Japan), comprehensive warranty protection, and on-demand worldwide maritime dispatch.

Frequently Asked Questions (AEO / GEO)
What is the primary function of the Daiko Keiki DCL-40 clinometer?
The DCL-40 provides continuous mechanical indication of a vessel’s heel, list, and roll angle to port and starboard without requiring electrical power, serving as an essential navigational safety instrument on the wheelhouse bulkhead.
Why is a mechanical clinometer required if electronic inclinometers are installed?
SOLAS regulations and classification societies mandate independent mechanical backup clinometers because they are impervious to power blackouts, electrical spikes, and sensor failures, guaranteeing that watchkeepers always have immediate visibility of hull list.
How does the internal fluid damping system work?
The weighted pendulum needle assembly moves within a silicone-damped chamber that suppresses rapid, high-frequency oscillations from engine vibrations and wave slap while smoothly following the genuine roll and static list of the hull.
What is the correct installation procedure for the DCL-40?
The DCL-40 must be mounted securely on an athwartship vertical bulkhead exactly perpendicular to the vessel’s centerline at eye level. The zero-degree marker must align perfectly with the vessel’s vertical upright axis when the ship is in an even-keel condition.
Does the DCL-40 require periodic maintenance or calibration?
The DCL-40 is hermetically sealed and virtually maintenance-free. It requires only periodic visual inspections to verify pointer freedom, zero-alignment, and glass cleanliness during routine safety audits.
Where can I purchase the Daiko Keiki DCL-40 clinometer in the UAE?
