Gauss meter

Gauss meter LZ-641H is one of the LZ Series Gaussmeter products which is used in both AC and DC field. As a specialized handheld gaussmeter, it is a magnetic field test equipment which has been designed for on-site testing. It could test the surface field of permanent materials and working magnetic field of DC motor, amplifier, magnetic separator and permanent de-ironing separator. It also could be used in the measurement of remnant magnetism of mechanical processing, magnetic polarity, remnant demagnetizing field of products, to control the magnetic condition of electroplating staffs and test the motor magnetism, leakage of electromagnetic field and AC space field. Main features. Small and light, easy to take, could meet all kind of on-site test requirements.Power down automatically when no operation over 40 seconds.Lower voltage indicate.Super low power consumption design.It could be used more than80hours continuously.DC or AC peak hold.DC and AC magnetic field,two range 0-200mT,0-2000mT.DC field polarity judgement function.One-click Quick automatic zero adjustment.Users can select the transverse and longitudinal probes accordingly.Exchangeable probe.

Transverse proble The naming of Hall probe There are two kinds of Hall probes, they are transverse probes and axial probes. Each kind of probes adopt 8-bit encoding:Take T2-0612M as an example,the first letter is T or A, T indicates transverse probe, and A means axial probe. The second number indicates the number of stalls of the range. The third one is fixed to "-". The fourth and fifth numbers indicate the length of the probe, and the unit is cm. The sixth and seventh numbers are the thickness of the transverse probe or the 10 times of the diameter of axial probe, and the unit is mm. The eighth one is H, M, L or U, which indicates magnetic field strength that the probe is applicable and the minimum resolution.H represents high field, minimum resolution is 0.1mT(1Gs).M represents middle field, minimum resolution is 0.01mT(0.1Gs).L represents low field, minimum resolution is 0.001mT (0.01Gs).U represents extreme low field, minimum resolution is 0.0001mT(0.001Gs).For example: T3-0512H means transverse probe, the minimum resolution is 1Gs, the length of the probe is 50mm, thickness is 1.2mm, and can collocate to the two stalls gaussmeter.How to chose a Hall probe Usually magnetic test equipment manufacturers have many types of test probe to meet every test requirement. Users should consider if the probe meet the test requirement when choosing Guassmeter. Equipment test range and resolution: it is not only decided by the test probe, but also the equipments. Users should consider the magnetic field and test requirement when choosing equipment.Air gap field testing: Consider the size of test probe, such as if probe could not be used, when its size is bigger than the test air gap.Direction choosing: Two types of direction: Transverse and longitudinal, users should choose the proper probe according to the test materials, such as: Transverse probe is often chose to test electromagnetic field and surface field. Choose the longitudinal when test the magnetic field of solenoid.Probe connection line: The length of the probe line is usually fixed, if you have special test requirement, you should notice the manufacturer to extend or minimize the test probe line.Test tooling: In some special test occasions, we need equip the professional test tooling to make sure the test accuracy and comparability of repeat test.Package
