For DC and AC Current and voltage. The operation of these meters depend on the reaction of the current circulating in the moving soil and da field of a foxed 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 and also alternating current with a suitable rectifier in the circuit.

Accuracy:DC+F.S.F.

Scale Length:60 mm approx. with knife edge pointer and anti parallel mirror scale.

Dial Size:80 x 80 mm Rectangular.

Moving Coil Multirange Voltmeter has following ranges:-

a) DC&AC 0-5 25-50-100-250-500V

Moving Coil Multirange Ammeter has following ranges:-

DC&AC 10mA -100 mA -500 mA -1A-2.5A-5A

A hand board disc with twelve 50 x 3mm. slots and finger hold, pivoted on a ball bearing mount which also acts as a convenient handle. Diameter of disc. 255mm.

POTOMETER

This apparatus allows the student to measure transpiration with minimal risk of breakages. This is a used for laboratory and field use. This apparatus can also be used tomeasure humidity by connecting a porous pot to the third outlet. This apparatus has only one glass component (the capillary tube) and is mounted on a strong backing plate. It consists of a capillary tube with millimeter scale connected via. 3-way tap to a syringe. The cut shoot is connected to the third outlet.

PR-296 MOUNTED JOULE METER

A domestic electricity meter adopted to operate single-phase 2, wire c1.2 ma x 8.33 a 12 v 50 hz. 0.01 rev. / j and dials reading in joules. The meter is mounted on a wooden bench stand input and output socket terminals. The aluminium disc rotates once for every 100 joules with the consumption recorded on three digits calibrated 100, 1000 and 10000 joules per division respectively. The instrument records a maximum of 99, 900 joules.
