AG-858 portable cesium magnetometer proton-pump product information
AG-858 cesium magnetometer-pump
New AG858 Professional magnetometer, it is a super-fast, highly effective tool for measuring magnetic mapping. The system operators to provide quick visual function, which can watch five superposition profile measurement and measurement grid, which has been showing a multi-functional package, it can transfer, edit data, according to two-dimensional or three-dimensional contours Interpolation data format. Data entry within a few minutes after the main computer that can be drawn with all the notes Wallpapers.
Main features:
High sensitivity ---- easy to detect buried 15 feet deep drums
Efficient ---- 2 m measured from the line, one hour, can detect more than 8,000 square meters
---- Visual display measuring grid, location and five superimposed profile
Easy to use ---- a standard IBM compatible, printer or plotter in the base stations within a few minutes to copy a map
At the same time the use of options -----level vertical gradient, GPS differential GPS (accuracy of better than 1 m) and goals analysis software
Specifications:
Magnetometer / electronic circuits
How it works: Since the oscillation discrete beam of cesium vapor (non-radioactive CS-133)
Scope of work: 17,000 ~ 100,000 nT (γ)
Regional work: In order to achieve the highest signal to noise ratio, to probe the long axis and the angle between the magnetic field should be 45 ± 30 °, but is generally operating in 40 ± 30 ° under the conditions. Probe in all the hemisphere to work automatically switch.
Sensitivity: (90% readings in the scope of P-P)
Measuring 0.1 s rate of 0.15 nT measured at 0.2 s at the speed of 0.11 nT
Measuring speed of 0.5 s at the rate of 0.07 nT measured 1.0 s at 0.05 nT
Broadband Information: <0.02 nT (γ) / √ Hz RMS
Position Error: <± 1nT (γ) temperature drift: 0.05nT (γ) / ° C
Gradient Tolerance:> 500 nT (γ) /-> 20000 nT (γ) / m
Sampling interval: 0.1 s ~ 1hr (each step 0.1 s) or the trigger
Data storage: Solid of RAM capacity: magnetometer, the signs of time, location records, eight hours; plus gradiometer, GPS, the highest sampling rates, three hours.
Audio output:
1). Geomagnetic fluctuations in the audio signal, pitch and volume control (search)
2) an audio pulses per second (measured step rhythms)
3). Signal loss or low-voltage battery alarm
Data output:
3-RS-232 standard Kushibiki mouth, through the RS-232 for real-time transmission of data to a PC (option). Chuan output to less than 5 min.
Screen output: 320 micro-controller-driven liquid crystal displays, sunlight-200 ×
Optional output are:
1). Data show: five superposition profile, real-time or re-display mode
2). Functional system settings: the state of memory, data transfer, sampling time
3). Survey set features: survey number and profile direction, GPS stations or serial number, the pilot test line,
4). Survey monitoring function: the total magnetic field, noise level, the profile of X or Xy coordinates.
Interior clock: resolution of 0.1 s, drift <1 s / day
