Please Note That the Standard Shipping Included Axial Probe and Hall Probe. Introduction: The design of hand-held digital Tesla meter follows the IEC-61010-1 safety standard, and conforms to the national verification regulation of JJG242-1995 Tesla meter. TD8620 hand-held digital Tesla meter adopts not only the high-sensitivity Hall sensor and high-resolution A / D conversion chip, but also the popular single-chip computer technology and digital filtering technology . It has the advantages of high sensitivity, stable reading, low power consumption, and light weight. The measurement range is 0-2000 Mt,It has the characteristics of automatic zero, automatic measurement range, keeping of maximum / minimum values, etc. Features: Dedicated to measuring the surface flux density of permanent magnet materials B, range: 0 to 2400 mT The value can be switched by one button: mT (mite) or G (gauss). With automatic zero and auto range, and maximum hold function. With backlight adjustment, power display and automatic shutdown function. Light weight and low power consumption.
