    Magnetic Field Detectors

    Image of Product. Front orientation. Magnetic Field Indicators. 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.

    Digital Electromagnetic Field Indicators

    Image of Product. Front orientation. Magnetic Field Indicators. Digital Electromagnetic Field Indicators.
    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 indicators store up to 20 radio frequency readings. Send readings to your PC using a USB cable (not included).

    Protective Case

    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.
