A domestic electricity meter adopted to operate single-phase 2, wire C1.2mAx8.33 A 12V 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.
Portable type, having large display of 3½ digits, type LCD, power 9 Volts battery, accuracy + 1 digit, size 125x65 mm.
