Portable Instrument Multi Range And Multi Parameter (Medium Size Multi Range With Bakelite Housing)

DESCRIPTION

Protable Moving Coil DC, Moving Coil Rectifier type AC, Moving Iron AC ammeters & voltmeters and can be used in conjunction with transducers for measurement of frequency, power factor and low power factor wattage. Single phase dynamometric instrument is used for measurement of power at Unity Power Factor (UPF).

 

FEATURES / ADVANTAGES
•	Instruments with accuracy class 1.0, 1.5.
•	Instruments with multiple scale (refer table).
•	Robust housing suitable for schools, workshops, field operations, for continuous use.
