Product Description
Our marine magnetometer is a device used to measure the strength and direction of the Earth's magnetic field in the marine environment. It is a type of instrument commonly used in geophysical surveys of the seafloor for detecting and mapping magnetic anomalies.
One of the key features of this device is its wide survey range, which can measure magnetic fields ranging from 10000nT to 105000nT. This means that it can detect even the slightest variations in the magnetic field, making it ideal for a wide range of applications.
Another important feature of a marine magnetometer is its gradient tolerance. This refers to the device's ability to measure changes in the magnetic field over a distance. A high gradient tolerance of 45000nT/m means that the device can accurately measure changes in the magnetic field even in areas where the gradient is steep.
In addition to its wide survey range and gradient tolerance, a marine magnetometer is also highly sensitive. With a sensitivity of 0.0006nTN/ Hz RMS, it can detect even the smallest changes in the magnetic field. This makes it an invaluable tool for a variety of applications, including mineral exploration and geophysical surveys.
Finally, a marine magnetometer is known for its high accuracy. With a precision of 2.5 nT, it can provide accurate and reliable measurements of the magnetic field. This level of accuracy is critical for applications such as marine navigation and mapping, where even small errors in measurement can have significant consequences. Overall, the wide survey range, gradient tolerance, sensitivity, and accuracy of a marine magnetometer make it an essential tool for a wide range of marine research and exploration applications.
