Laboratory Measurement Systems
This division covers the measurement chain that supports materials synthesis, characterization and electrochemical testing. Start with the measurement quantity, understand how a sensor or instrument converts it into an electrical signal, then evaluate the uncertainty before interpreting the displayed value.
Digital Multimeter (DMM)
Voltage, current and resistance measurement; input impedance; ADC architectures; integration time; accuracy and uncertainty.
Thermocouples and Temperature Measurement
Seebeck effect, reference-junction compensation, cold-junction sensors, wiring, calibration and temperature controllers.
Oscilloscopes
Voltage probes, attenuation, sampling, bandwidth, triggering, aliasing and waveform reconstruction.
Source-Measure Units (SMU)
Four-quadrant operation, source and measurement ranges, compliance, guarding and I–V characterization.
Mass Flow Controllers
Thermal sensing, gas-specific calibration, control valves, reference conditions and flow verification.
Pressure Transducers
Strain-gauge, capacitive and piezoresistive sensing; gauge, absolute and differential pressure.
Learning sequence
- Digital multimeter: understand voltage, current and resistance as measured electrical quantities.
- Thermocouples: understand how a physical temperature difference becomes a voltage.
- Oscilloscope: understand time-dependent signals, sampling and bandwidth.
- SMU: combine controlled electrical excitation with precision measurement.
- Flow and pressure instruments: connect sensor physics to process control.
