Dual Tube Type Clinometers — IMPA 370242

Dual tube type clinometers (IMPA 370242) are essential onboard instruments for real-time monitoring of a vessel's heel (port/starboard list) and trim (fore/aft inclination). They are widely used on cargo ships, container vessels, tankers, bulk carriers, and offshore support vessels. Mounted on the bridge, deck, or any level platform, they help the crew quickly assess the ship's attitude during navigation, cargo loading and ballasting, and port operations—reducing the risk of excessive list, cargo shift, or stability-related incidents.

The instrument features a dual-tube design: a fine-scale upper tube for precise micro-readings and a large lower dial for quick visual reference. It measures inclination up to ±60° with a graduation of 1°, accuracy of ≤±0.4°, and sensitivity of ≤1.4°. The housing is built to withstand harsh marine conditions, offering water resistance, dust protection, and impact resistance against high humidity, salt-laden air, and vibration. Weighing approximately 0.4 kg and measuring about 50 × 240 × 360 mm, it operates on a simple gravity-based bubble principle: when the vessel tilts, the bubble moves toward the higher side, allowing direct reading against the scale.
