Portable Ammeters Or Voltmeters

Portable Ammeters and voltmeters are designed for use in the field test rooms and laboratories, where precise measurement is required. These portable Instruments can be used equally well in educational institutions, where there is possible misuse; and in factories, where these instruments are important for making calibration check on switchboard panel instruments. General features:
Knife edge pointer and Anti-parallax mirror scale
Shock resistant pivot jewel movement. The pivots are made from carbon steel hard chrome plated and are mounted on spring loaded sapphire jewels. This ensures shock resistance due to vibrations in transit and minimum friction during use.
Accuracy class 1.0% as per IS:1248
Wooden case with Bakelite Top
Wide window for easy reading
Quick response due to unique damping
Scale Length 150mm(approx)
Insulation Resistance Over 20 megaohms at 500 VDC
Sensitivity 1000 ohms/V for DC Meters
Test Voltage 2000V AC (rms)for 1 minute
