These meters are developed to teach easily constructional features of permanent magnet moving coil type. Movement is fitted in the transparent wooden box and internal electrical connection are made visible. These meters can be used for demonstration and also for actual measurements. Accuracy Class : 2.5 Scale Length : 110 ± 2 mm Overall size : 80 x 100 x 190 mm approx.
Housed in a ABS plastic case 300 x 150 x 300mm ( 18.50" x 8.70"x 16.90" ) with glass front and rear. Moving coil type with an accuracy of +/- 2.5%. Basic sensitivity of meter is 5mA, 100mV f.s.d. The meter can be used to demonstrate the working principle of AC or DC amp meters or voltmeters with the interchangeable plastic scales.

Operates on 4-6 volts DC.
Mounted on molded ABS base. Operates on 4-6 volts DC.
Open type demonstration motor with magnets mounted.
Open type demonstration motor with magnets mounted. Simple construction is very good for students understanding the concept of electromagnetism.
The motor consists of a two pole D.C. armature. The brush holder, with
two heavy binding post terminals, may be rotated for experiments. The
permanent bar magnets are supported by spring brass clamps which are
unadjustable in the horizontal plane to show the effects of pole
separation. Complete with two bar magnets, a two pole DC armature.
Specially designed for students to learn electromagnetic forces. All
parts visible and polarity of the magnets can be reversed to change the
direction of the rotation. It can be used with a rheostat to observe the
change of speed with the change of current. Operates on 1.5 V battery
which is not included.
Large size mounted on molded ABS base.
Large size mounted on molded ABS base. Operates on 6-8 volts DC with Newton's color disc.
