ECG eCompass Series
Highlights:
If your compass application involves vibration, acceleration, uneven terrain, or rough seas, the ECG Series, a gyro-stabilized electronic compass, is an uncompromising solution that will outperform rival units that cost more. The ECG provides remarkably accurate heading, pitch, and roll in dynamic conditions. It all starts with a precision 3-axis solid-state magnetometer. Two angular rate gyros independently stabilize pitch and roll. They augment a dual-axis, electrolytic tilt sensor that provides precise tilt measurements in static environments. Two sets of independent filters, one set for pitch and one for roll, combine gyro and electrolytic sensor measurements to provide the best available tilt measurements.
ECL eCompass Series
Highlights:
The ECL low-power digital compass is designed specifically for commercial, industrial, and military users. The ECL series will be of particular interest to ROV and AUV manufacturers who are concerned with power usage and accurate heading in all types of challenging conditions.  In standby mode, it draws a mere 50 microamps and requires only 15 mA in run mode. It provides accurate heading data in less than a tenth of a second from wake up. An extended range tilt sensor is available that allows for ±60° of pitch and roll.
ECS eCompass Series
Highlights:
The ECS digital compass represents the state-of-the-art in magnetic compassing. It combines a precision 3-axis solid-state magnetometer and a rugged 2-axis electrolytic tilt sensor to provide accurate heading and tilt measurements over a wide range of environmental conditions. The firmware and signal processing algorithms have been refined and improved over three prior generations of compasses to deliver the ultimate in performance from the available sensor data.
Model A800P Portable Tiltmeter
Highlights:
The Model 800P Portable Tiltmeter is a versatile and accurate hand-held instrument for monitoring structural and foundation movement. Measurements are taken from tilt plates that have been cemented or bolted to any horizontal or vertical surface. Indexing bars on the bottom and sides of the tiltmeter enable you to reposition it accurately on the tilt plate, every time. When continuous monitoring is not required, Model 800P is an excellent choice because only one tiltmeter is needed to make measurements at an unlimited number of points.
The Portable Tiltmeter System includes one tiltmeter, one power and display unit, and a tough plastic carrying case. Ceramic or Aluminum Tilt plates are purchased separately.
