GMR50 Low-intensity Magnetic Field Gaussmeter


 
Description:

With 15 years’ experience in precision magnetic field measurements, COLIY adopted the new GMR (Giant Magneto Resistive) sensor to produce a gaussmeter used to detect low-intensity magnetic field, GMR50 Gaussmeter. GMR50 could be used in traffic monitoring, navigation, surveillance, geomagnetism measurements and so on, and suitable for scientific research institutions, universities, laboratories, industry, manufacturing and other users. GMR50 boasts with an industrial class 3.2 inches touch panel display that enables customers’ instantaneous and simultaneous measurement results (DC/ AC/ Max/ Min/ Peak/ Hold/ Alarm/ Polarity, Magnetic Flux Intensity, and a Trend Graph etc.).

Gaussmeter GMR50 allows measurements up to 45G (4.5mT) with the reading-based accuracy of 1%, the resolution of 0.1mG (0.01μT), and the frequency response of DC~ 100Hz. GMR50 could be equipped with Axial Probe and Transverse Probe.

Precision Description of COLIY Gaussmeter

l  When using gaussmeter to measure magnetic field in the environment that ambient temperature changes obviously, it’s recommended to use temperature sensor contained probe with the gaussmeter. Temperature sensor contained probe has the function of temperature compensation for better precision and stability when the temperature changes. 

l     Difference in rated accuracy between COLIY Gaussmeter and other brand’s Gaussmeters: the accuracy of COLIY is based on the reading, but other brand’s Gaussmeters’ accuracy is based on the selected range. So COLIY Gaussmeter’s measurement data is more accurate than other brand’s Gaussmeters’ when all the Gaussmeters’ accuracy is in a same value, and all the Gaussmeters work under the same working conditions. For example: When using COLIY gaussmeter and other brand gaussmeter, whose rated accuracy is 1%, to detect a magnetic field at 500G, COLIY gaussmeter readings range is 500G ± 500 * 1%, but other brand’s gaussmeter readings range is 500G ± 3000 * 1%, (3000G is the most appropriate range in such condition).
