PM-2 proton magnetometer
PM-2 proton magnetometer uses the operating principle of proton precession to measure the total absolute value of Earth-magnetic zone. It can work in two modes:
Range of Application:
- Mineral exploration, iron ore,lead zinc ore,copper ore ,etc.
- Cooperate with mineral survey, research on buried depth, attitude and continuity of mineral ore, research on shape and size of mineral ore, estimate the scale of mineral deposit
- Exploration of petroleum, natural gas, research on geological structure and geo-structure in connection with gas/oil
- Reconnaissance survey, detail survey, geologic mapping
- Surface daily change station of geomagnetic survey of aviation and ocean
- Fault location
- Archaeology
- Hydrology
- Engineering survey,pipeline detection, etc.
- Monitor the earthquake precursors, volcano survey, other environmental and isastrous-geological work.
- Detection of minor-scale ferromagnetic body, etc.
Main Features:
- Single point mode: Only one sensor is used to detect the total absolute value of earth-magnetic zone where the sensor is.
- Automatic mode: Only one sensor is used in automatic mode, which can start the instrument at set time and automatically do measure work by a fixed time interval repeatedly. The starting time and time interval can be set by software. This function is mainly used for daily change correction.
- Used for measuring the total field of the terrestrial magnetic field and gradient measurement (horizontal gradient or vertical gradient, special probe and probe rack are needed.).
- Used for both field work and base station measure.
- Built-in real time clock, measurements are stored with sampling instant. Even timing measure and storage can also be realized
- Both full scale automatic tuning and manual tuning.
- The whole system is equipped with backpack and braces so that the measure work can be finished by single.
- Two kinds of computer interface: USB, RS-232C
- Professional geologic software used to protract isoclines map, profile map and so on.
- Memory 240,000 measuring point with the function of blackout protection.
