Ferronato® - BH300-3-A
--- Desktop set of three pairs of Helmholtz coils for laboratory and general purposes.
--- Suited for many magnetic measurements and experiments, in DC and AC.

|Maximum current||4.0 A in a steady mode / 6.0 A during 2 minutes (start temperature: 20 ºC). Each pair.|
|Isolation voltage||250 V DC minimum, between windings and their forms and between pairs. Tested to 500 V DC.|
|Magnetic field homogeneity||Differences smaller than ±1% with respect to the centre, in a spherical volume of 70 mm of diameter, centred in the coils. Differences smaller than ±5% in a spherical volume of 100 mm of diameter. Volumes to 1% and 5% greater on some directions.|
