DC Gaussmeter Model DG-20K

DC Gaussmeter DG-20K


Product Description:

This small and powerful Gaussmeter measures the strength and polarity of magnetic fields up to 19,999.9 gauss! The sensor can easily fit in a .060 inch (1.5 mm) gap and is at the end of a 100 cm flexible cable. The sensor end can be bent if required to accommodate different situations. Place the sensor on a magnet face to measure the field. With a resolution of 0.1 gauss, it can measure any tiny variation from magnet to magnet or it can detect if a given magnet has lost even a little strength. Bend the sensor in to a “L” to measure inside a DC solenoid tube. The 5 ½ digit display requires neither auto nor manual range change, making it easier to use than older style 3 ½ or 4 ½ digit meters. Immediately starting reading fields (updates 4 times per second) as soon as you turn on your meter! No extra set up is required.


  • High dynamic range 5 ½ digit display reads even the strongest magnets with .1 gauss resolution, including polarity.
  • Turns on instantly, updates four times a second, no setup or initial calibration required.
  • Auto-Zero (subtracts the present field from subsequent readings); also a fine offset control.
  • Offset range is the full +/- 19,999.99 gauss.
  • 1% accuracy at room temperature, including probe.
  • Probe and battery included.
  • CE Compliant.


  • Measures permanent magnets. (Maximum field of magnets is about 15,000, which occurs only with rare-earth magnets in a gap configuration.)
  • High resolution of 0.1 gauss over the entire range of +19,999.9 to -19,999.9 gauss allows detection of any variation in field from a magnet.
  • Measures inside DC Solenoids (probe is bent into “L” shape to measure this).
  • Sufficient resolution to map fields far from magnets.
