I want to build a measurement system. It includes 2 separate measurements: conductivity and low DC voltage.
1. Conductivity measurement: Just take resistance measurement at various temperatures, automatically record and graph Conductivity - Temperature (converted to conductivity by applying the standard equation).
2. Low DC voltage measurement: With constant current applied, I want to measure low voltage(0.01 mV-10 mV) on 2 parallel channels at various temperatures. Record both channel data together and take a relative graph (V-V graph) to take slope value (similar above).
What equipment would I need to purchase to achieve this?
