An electronics board (kit) that allows you to connect up to 30V AC or DC on one side of the board and get adjustable VDC regulated on the other side. Every lab should have a few of these boards handy. The boards will allow you to easily power all your analog components (i.e. op-amp). The Terminal Block TB connector is included and makes it easy to use.
Build your own Conductivity meter and/or controller and save. Simply connect your Conductivity cell (conductivity electrode, Probe) to the input via Terminal Board (TB) and the output to analog to digital converter (ADC), Digital voltmeter (DVM), Analog Voltmeter, micro-controller (MC) or PLC.
