Digital voltmeter is an instrument used for measuring the potential difference between two points in an electric circuit. The voltage can be measured by allowing it to pass a current through a resistance; therefore, a voltmeter can be seen as a very high resistance ammeter. Digital ammeters are instruments that measure current flow in amperes and display current levels on a digital display. These devices provide information about current draw and current continuity in order to help users troubleshoot erratic loads and trends. They have both positive and negative leads and feature extremely low internal resistance.

Digitally Controlled motor pump integrate easily into manufacturing processes, lab environments, oem applications, and custom projects. It generally requires a flow meter, regulator to maintain accuracy and control over the flow rate. Digitally controlled valveless fluid motion ensures maximum repeatability of fluid delivery, and increases the process control. It controls flow rate by the speed of the motor. An internally-sealed, valveless fluid path within the pump head provides fluid control. It is designed for exceptional precision. It delivers exceptional accuracy and reproducibility for demanding application.
