An instrument for measuring the energy distribution, or spectrum, of gamma rays, whether from natural or artificial sources. It is used in airborne remote sensing for potassium, thorium, and uranium.
Industry:Mining
An instrument for measuring the heat generated by an electric current or for measuring the current by the heat that it generates.
Industry:Mining
An instrument for measuring the insulation fault at low voltage without polarization. This instrument is more informative in checking detonators in loaded holes than the insulation meter.
Industry:Mining
An instrument for measuring the vapor pressure and the relative humidity of the air or the quantity of moisture in the air. It consists of a dry-bulb thermometer and a wet-bulb thermometer, the latter having its bulb covered with a layer of muslin kept moist with water. The rate of evaporation from the moist muslin depends upon the quantity of moisture in the air. The more rapid the evaporation, the greater the cooling, and hence the greater the difference in the temperature readings of the two thermometers.

Industry:Mining
An instrument for measuring variations in the vertical component of the terrestrial magnetic field, usually by balancing the torque on a magnet system by means of a counter gravitational torque acting on counterweights.
Industry:Mining
An instrument for measuring water and water-ore slurries in ore dressing and coal dressing processes.
Industry:Mining
An instrument for metallurgical research. It can create visual images of the minutest particles in metals and alloys by use of X-ray beams. Magnification is up to 3,000 times, and particles smaller than a millionth of an inch can be examined in detail.
