Portable Ammeters & Voltmeters are designed for use in the field, test rooms and laboratories where precision measurement is required. These Portable Instruments can be used equally well in precision research laboratories where carefully controlled atmosphere conditions are secured, in educational institutions where possible misuses exist and in factories where these instruments are important for making calibration check on switchboard and panel instruments.

Ltekonline are the manufacturers of Three Phase Voltmeter used to demonstrate engineering principles in Engineering Colleges, Engineering Schools and Test and Measurement Instruments for Engineering Teaching Lab in Universities
