Digital Panel Meter operators on the principle of dual slope integration. It is available in two types i.e. 31 / 2 digit & 41 / 2 digit. Digital frequency meter incorporates microcontroller with crystal oscillator to display the frequency. It is available in 4 digit type.

Dynamometric instruments are used for measurement of active, reactive & absolute power in 1 phase & 3 phase systems for balanced / unbalanced load conditions. Watt, Var & VA instruments incorporate current coils, which are connected in series with the load & pressure coils of fine wire gauge, which are connected across the road. These instruments work on “Air cored Electro-Dynamometric” principles.

Maximum Demand meter is used for monitoring thermal loading in Power Distribution systems, networks, machine etc. It indicates maximum loading current over a period. Short-period current perks are not registered but long overloads are registered.

It incorporates solid state circuitry with micro-controller to measure Power Factor of Single Phase and Three Phase System.

“AE” Built in Transducer type Digital Power Meter is equipped with a measuring transducer & Digital indicator. It measures Active, Reactive & Apparent power in Single Phase & Three Phase System.
