1 nanotesla (0. 01 mgaz) resolution is within a full range of ±100,000 nanotesla (1 goss)。
The basic accuracy of 0. 25% can be traced back to nist。
Displays three vector components simultaneously。
The operator may choose an on-site unit (nanotesla, microtesla or milligaus)。
An optional vector coordinate system (reverse or polar) for operators。
Absolute or relative display mode。
Remote rs232 operation。
Two simulation outputs per axis。
Three data storage modes: snapshots (7. 5 seconds), records (30 seconds) and manual。
U. S. Meda fvm 400 vector magnetometer, fvm 400 magnetometer application
The fvm 400 vector magnetometer is a four-line, 16-word hand-held three-axis magnetic magnetometer. It's a precision instrument for measuring the vector mass of weak magnetic fields. All three vector components are displayed simultaneously。
Us meda fvm 400 vector magnetometer, typical applications of fvm 400 magnetometers include:
Packaging inspection
Material screening
Block performance
Field map (includes location - see below)
Magnetic environment control
Magnetic rectangular measurement
Magnetic tag determination
Fvm400 uses magnetic portal technology to measure the three vector weights of the magnetic field. Magnetic door sensors are enclosed in a 4-inch long probe, which is connected to handheld electronic devices through modular telephone lines. Sensors can be installed 100 feet from the electronic unit。
In rectangular coordinates, fvm400 shows the weight of the magnetic field vector. In polar coordinate mode, fvm400 shows the size and direction of the field vector。
Fm300 package
You can remotely control fvm400 to the computer's serial port via rs232 connection. With fvm 400, the fm300 front panel package is available. The package includes the fm300 front panel and fm300 network servers。
Use the fm300 front panel program, you can
