Summary WT10F series handheld digital Gauss meter / Tesla meter can be used to measure DC magnetic field. It is mainly used for detecting the surface residual magnetization of ferromagnetic material shielding, the sensitivity of 0.0001Gs (i.e. equal to 10nT), or analog magnetic field on the simulation environment of the geomagnetic field measurement. The display is clear and reliable. The instrument can carry, easy to operate, clear liquid crystal display. Power supply for the 6 section of the dry battery 5, external voltage regulator. Main Technical Index Range: 0~1.9999Gs Basic error: + 2% + 3 words Resolution: 0.0001Gs (equal to 0.1mGs) Measured magnetic field: DC magnetic field Ambient temperature: 5 ~40 Relative humidity: 20%~80% (no condensation) Power supply: six section 5 dry battery, external power supply(not included package) Dimensions: 150mm (L) * 70mm (W) * 30MM (H) Instrument weight: 450g Display mode: 4 1/2 LCD Display unit: Gs
