• Very low temperature drift
• Low dc input bias current-10pA
• Measures voltage down to 1µV
• Automatic polarity indication
• Recorder facility (optional)

Digital Microvoltmeter, DMV-001 is a very versatile multipurpose instrument for the measurement of low dc voltage. It has 5 decade ranges from 1mV to 10V with 100% over-ranging. For better accuracy and convenience, readings are directly, obtained on 3½ digit DPM (Digital Panel Meter)

This instrument uses a very well designed chopper stabilized IC amplifier. This amplifier offers exceptionally low offset voltage and input bias parameters, combined with excellent speed character-istics.

Filter circuit is provided to reduce the line pickups of 50Hz. All internal power supplies are IC regulated.

APPLICATIONS :

• DC voltage measurements from high impedance sources; output of photomultiplier tubes, photocells, radiation detector etc.
• Very low voltage measurement, direct measurement of thermo–couple output to read temperatures with a resolution of 1/40th of a degree (Chromel-Alumel)
• General purpose laboratory instru-ment for voltages upto 19.99V DC
• (Hall Effect, Four Probe, Thermoluminescence, Transistor and Diode characteristics etc.
