ALPHALAB GM1-ST Portable Digital Gauss Meter

GAUSS METER 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 Detachable Rubber Boot Included   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.   SPECIFICATIONS: 1-axis DC Gaussmeter GM1-ST Resolution: ±19,999.9 G with polarity indicator Resolution: 0.1 G Accuracy: ±1% of reading (16° to 29°C); ±2% (-4° to 65°C) Offset: Auto-Zero.
