Analog Voltmeters
Alliance Engineering Company
Alliance Engineering Analog Voltmeters are moving iron (AC) and moving coil (DC) panel instruments for accurate voltage measurement in industrial switchgear, MCC panels, DG panels, distribution boards, and control rooms. Available in 72mm, 96mm, and 144mm flush-mount square formats with full-scale voltage ranges from 30V to 600V AC and 30V to 500V DC (higher ranges via external PT). Class 1.5 accuracy as per IS 1248 with white dial face and black pointer for clear readability. Manufactured by Alliance (India) under ISO 9001:2015 standards.
