Lutron milliGauss AC/DC Magnetic Meter (BMG-3004SD) Bench Type

Lutron Precision and General Magnetic Meter with SD Card Real-Time Data Logging (BMG-3004SD)

The Lutron BMG-3004SD is a dual-mode magnetic field meter designed for both precision and general magnetic measurements. It supports DC and AC field measurements and features real-time data recording to an SD memory card without requiring special software. With two included probes (precision MI sensor and general Hall sensor), a wide measurement range, TFT color display, and computer interface capability, this bench-type meter is ideal for industrial, mechanical, electrical, materials testing, and laboratory applications.

• Two-in-one functionality: Supports precision measurement using an MI sensor probe and general measurement using a Hall sensor probe.
• Real-time data logging: Saves readings directly to an SD card (one to sixteen gigabytes) for export to spreadsheet formats with no software required.
• Measures DC and AC magnetic fields: Suitable for low and high-intensity field environments.
• N-pole/S-pole indicator: Assists with magnetic polarity orientation.
• Zero adjustment: Zero button for DC magnetic measurements.
• Record functions: Data hold, maximum value, and minimum value memory recall.
• Separate probe design: Allows remote or confined-area measurements.
• Computer interface: RS-232 and USB output capability (via optional cables).
• Auto shut-off: Conserves battery life.
• TFT color display: High-visibility screen for clear readout.
• Power options: Six AA batteries (UM3) or optional DC nine-volt adapter.
