Digital Microvoltmeter

• Very low temperature drift

• Low dc input bias current -10pA

• Measures voltage down to 1µV

• Automatic polarity indication

• Built-in computer interface

Introduction  

Digital Microvoltmeter, 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 characteristics.

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

Computer 
 
  The unit can be connected
 directly to a PC through an USB.Data Access And Control is a built-in interface which gives user an option to store a value as displayed on the meter and tabulate it by the click of a button on the screen. Alternatively the data may be automatically entered into a table at user selectable interval. An 'END' button on the screen terminates the automatic tabulation. The Data stored in the table may then be displayed as a graph on the screen and may also be stored in an excel file for further processing. The software supplied with the unit is menu driven and simple to operate

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 instrument for voltages upto 19.99V DC. (Hall Effect, Four Probe, Thermo luminescence, Transistor and Diode characteristics etc.)
