Magnetic Field Detectors
Troubleshoot solenoid valves, check relays, and test permanent magnets by detecting if a magnetic field is present. Hold these detectors near a surface and they'll light up blue if they sense a magnetic field. They don't measure the strength or direction of the magnetic field.

Calibrated-Dial Magnetic Field Indicators
Calibrated at 72° F. In addition to measuring the strength of a magnetic field in gauss, these indicators also measure the direction of a magnetic field in positive/negative. To take a measurement, place the lower edge of the indicator near or against your tools and parts.

Calibrated-Dial Magnetic Field Indicators with Certificate of Calibration
These indicators come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. All are calibrated at 72° F. In addition to measuring the strength of a magnetic field in gauss, they also measure the direction of a magnetic field in positive/negative. To take a measurement, place the lower edge of the indicator near or against your tools and parts.
Dial Magnetic Field Indicators
Place the lower edge of these dial indicators near or against your tools and parts to measure the strength of a magnetic field in gauss.

Digital Magnetic Field Meters
Measure magnetic fields to determine electromagnetic interference and detect flaws in welded metal. Product regulations restrict sales to the listed jurisdictions/areas.

Digital Electromagnetic Field Meters
Measure the strength of magnetic fields, electric fields, and radio frequencies at the same time. To detect emissions, just point these meters at the electrical equipment you want to test, such as a cable. When they detect high levels that could damage sensitive equipment, an alert appears in red and an audible alarm sounds. Their color LCD display shows readings, bar graphs, and trending graphs.
These meters store up to 20 radio frequency readings. Send readings to your PC using a USB cable (not included).

Motion-Measuring Modules for Development Boards
Measure your device's acceleration, rotation, or orientation. These modules gather data over time and track movement, which can help improve performance, debug issues, and calibrate your components. Solder them onto a development board. To connect them to your device, solder on a wire or header. For a solderless connection, use a Qwiic cord (not included).
An accelerometer measures the rate at which your device is speeding up or slowing down. A gyroscope measures how fast your device is rotating. A magnetometer measures your device's orientation.
