TM9100-HC Standard Magnetic Field with Helmholtz Coil
A standard magnetic field of ± (0.1 mT ~ 100 mT) can be generated by excitation with a high-precision DC standard current source. Calibration of a DC magnetometer with a radial or axial probe. The stability and accuracy of a magnetic field depends entirely on the excitation current, and can be directly regarded as a standard magnetic field. Two sets of probe position intelligent adjustment devices are installed on the coil, which drive the probe to move and rotate in the Y/Z axis by a precision stepper motor, and determine the best test point by intelligent adjustment and positioning of software. The coil is not only suitable for DC magnetometer calibration, but also suitable for various research institutes, colleges, enterprises to conduct electromagnetic interference simulation experiments, material magnetic detection experiments, etc., which is widely used.

• TM2800 Magnetic Shielded Cavity

 

 

 

1. The shielding frame is made of a shielding material with high magnetic conductivity, which removes the effects of the geomagnetic field.
2. The internal magnetic field <10^-6 T, which can be directly regarded as zero magnetism when calibrated.
3. Small, lightweight (about 1kg), compact and easy to carry.
4. The device is suitable for calibrating the zero point of a standard or calibrated magnetometer.

 

Magnetic Field Probe Position Controller
The software automatically recognizes whether an accessory is communicating properly with the PC, and visually displays in the configuration interface. The selected excitation mechanism is visually displayed in the interface of the software and can be freely switched. The calibration parameter units: mT, G, kG, Oe, kOe, A/m, kA/m. The software controls the Y axis, Z axis, and W axis of the standard probe and the probe to adjust the best test point of the probe, or enter the wireless mouse control mode. Automatically prompts you to switch between the range and the calibrated value of the input, and automatically enters the standby state if no input is entered within 2 minutes. Automatically calculates zero drift, which exceeds the permissible zero drift and is marked in red. An error is automatically calculated and compared to the permissible error, warning you with a red light for an excess value. Test data can be generated and exported as a calibration report.
