product description:
Tm4100b is a portable weak magnetic field measuring instrument. It is equipped with fluxgate sensor with high sensitivity, high linearity and low drift, and advanced digital signal processing technology. Compared with Hall effect magnetic measuring instrument, it can measure weak magnetic field in space more accurately. It is suitable for measuring remanence of magnetic materials or metal parts, monitoring environment magnetic field, geomagnetic detection, attenuation characteristics evaluation of magnetic shielding, magnetic field drift of precision instruments, package detection, geological exploration and other application scenarios that need to measure weak magnetism.
Features
1. Magnetic field measurement range: 1000 μ T, automatic range switching, accuracy level 2 or level 1 optional.
2. One key unit switching: the quantity value can be μ t (micro), Mg (milligauss) and other magnetic units.
3. Maintenance of maximum value: it is convenient to record the maximum value of magnetic field when the magnetic field changes rapidly.
4. One key clear function: used to eliminate the influence of zero drift on measurement before measurement.
5. Built in USB communication interface, convenient for data export or connection to sampling system.
6. Small size, light weight and low power consumption, it is very suitable for carrying to the site for measurement.
