Taiwan sun 138A 138A Gauss meter Gauss meter (Origin: Taiwan Sunshine) Product Description: 138A Gauss meter is used to test a variety of special instruments flux density of magnetic components, regardless of what is material and shape of the magnet can be used by Gauss meter 138A to test the strength of its magnetic field, measuring range: 0 ~ 20K gauss. General test method / Peak Peak lock function test method that can be easily measured peak flux density of the magnetic gap by adding automatic and automatic average test between magnet speakers, automatic four-point average sum test, accurate and efficient main purposes: having a peak to deposit and automatic accumulation, auto averaging function, suitable for use in speaker magnets, headphone magnets, a magnet microphone magnetic gap flux density measurements. Technical parameters: Digital Display: three and a half LED display, resolution: 1 gauss measuring range: 0 ~ 20K Gauss, two-speed automatic range switching a: 0 ~ 2.0K, b: 2.0K ~ 20.0K Gauss precision (test bar) : General Test: ± (0.1% Rdg + 0.05% FS.) peak hold: ± accuracy (overall) (0.2% Rdg + 0.1% FS.): At 10KGS: ± 1.7% (uniform magnetic field) 0 ~ 15KGS : ± 2.2% 15 ~ 20KGS: ± 2.5% four times the average error: ± 0.35% peak lock reaction time: <- 0.05% / sec sensing probe thickness: 0.5 mm ± 0.05 mm; 0.6 mm ± 0.05 mm Specifications: Dimensions. : 14 (L) * 22.5 (H) * 23 (D) cm Weight: 2.8KGS
