Janu Vol Issue 1 Pages A magnetometer is a device that measures magnetism—the direction, strength, or relative change of a magnetic field at a particular location. The measurement of the magnetization of a magnetic material (like a ferromagnet) is an example.A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth's magnetic field.

Get this from a library. Ampere-hour monitor for the electrochemical exploration technique. [Thomas P Grover; Geological Survey (U.S.)]. The ampere-hour display has six digits, far in excess of its accuracy, to meet the dynamic range requirement.

The operator needs to know if all electrodes have reasonable current flow after the first sample while the survey may require 10 samples. We can resolve 1 mA currents in one sample interval. The six-digit display can show 10 : Thomas P. Grover.

A two-anode reduction (TAR) technique is adopted to prepare, in one step without the existence of gaseous hydrogen, black TiO 2 nanotubes co-doped with carbon and nitrogen.

A sample prepared with the TAR technique for 2 min achieved the highest photocurrent response as mA/cm 2, which is 3 times as high as that of the pristine TiO 2 nanotubes.
