磁域高达19999.9的高斯The Gaussmeter Model GM1-ST measures the field of even the strongest magnet (to 20kG) down to fine resolution (0.1G). Features rapid turn-on and fast update. This model supersedes the MD1-ST, which had no auto-zero.Product Description:The Model 1-ST 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. Product Video (a previous version of this meter with a rotary knob on/off switch is shown):Gaussmeters: Model 1-ST and 1-HS demonstrationFeaturesHigh 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.Optional rubber boot and hard carrying case are available. CE Compliant. ApplicationsMeasures 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.
