Alphalab GM1-ST DC Gaussmeter

The DC Gaussmeter Model GM1-ST is measures 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 for a variety of 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. Turn on the meter and immediately begin reading fields (updates 4 times per second). There is no setup required, making this the fastest, easiest gaussmeter available.

Features

• Portable for easy measurements in factories or other industrial environments
• High dynamic range 5 ½ digit display reads even the strongest magnets with 0.1 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
• Certificate of NIST traceability included
• Probe and Battery Included
• CE Compliant

Applications

• Measures all 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
