Feature: 1. WIDE RANGE: The detector has two units: mT and Gs, and a wide measuring range of 0 to 2500mT (25000Gs), supports automatic range switching. 2. EASY OPERATION: The magnetic field detector has the functions of one key reset and maximum value holding, which is practical and easy to use. 3. BACKLIT DISPLAY: Digital screen with backlit function, you can observe the data clearly even in dim environments. 4. AUTO SHUT DOWN: The magnetic field detector can shut down automatically in 5 minutes to reduce power consumption, which is light weight and easy to carry. 5. WIDE APPLICATIONS: The tester is applicable to measuring the surface magnetic field of permanent magnetic materials, residual magnetism of mechanical parts, magnetic separator or iron separator, etc. Specification: Item Type: Handheld Magnetic Field Tester Material: ABS Range: 200mT (2000Gs), 2500mT (25000Gs) Scale Value: 0.01mT (0.1G), 0.1mT (1G) Accuracy (Level 1): ±1.0% Power Supply: 9V battery (not included) Working Environment: 0℃ to 50℃, 20% to 85% RH, no condensation Storage Environment: -20℃ to 70℃, <85% RH, no condensation Size: Approx. 160x75x34mm/6.3x3x1.3in Hall Probe: Standard radial hall probe, with a wire length of 1m.
