Moving Coil Multi Range Meter

Code: PHEE0109

For DC & AC current and voltage. The operation of these meters depend on the reaction of the current circulating in the moving coil an da field of a fixed permanent magnet. Considering the operational nature and design of these instruments, the scale is linear. Since the direction of the movement rotation depends on the direction of the current flow (polarity) in the circuit. The moving coil multirange meter can be used on direct current circuit and also alternating current with a suitable rectifier inserted in the circuit.
Accuracy DC + F.S.D. & AC + 2.5 F.S.D.

Water Circuit Board

Code: PHEE0113

This is an analogue apparatus to illustrate electrical current flow. It consists of a large board on which is mounted a low-voltage electric pump, connected to 4 mm socket terminals, which circulates the water through the 'circuit'. The circuit is of clear plastic tubing connected to glass tubes of differing bores representing resistance. Across the 'resistances' is connected a detachable manometer to show the 'potential difference'. Following the resistance is a taper-ended tube discharging into a funnel so that the rate of flow representing the current may be shown.
Dimensions of board 590x320 mm approx.
Dimensions of manometer 275x155 mm approx.
