Microtest 6365A/6367A LCR Meter for Electrochemical Applications

The Microtest 6365A/6367A LCR Meter is engineered for electrochemical applications where ultra-low frequency impedance measurement is essential. With a frequency range extending down to 0.1 Hz and up to 1 MHz at ±0.05% basic accuracy, this instrument addresses the specific requirements of battery cell characterization, fuel cell analysis, supercapacitor evaluation, and corrosion studies, applications where standard LCR meters with 10 Hz or 20 Hz minimum frequencies cannot reach the critical low-frequency impedance behavior.

Electrochemical Impedance Spectroscopy

At sub-Hz frequencies, the 6365A/6367A captures charge transfer resistance, diffusion impedance (Warburg elements), and double-layer capacitance that define electrochemical cell health and performance. The full frequency sweep generates Nyquist and Bode plots for detailed impedance spectroscopy analysis, enabling researchers to extract equivalent circuit parameters that model the electrochemical processes occurring within a battery cell, fuel cell membrane, or corroding surface.

Dual-Use: Research and Production

An 8 ms measurement speed at higher frequencies supports production-rate testing of battery cells and supercapacitors. This dual capability, sub-Hz research measurement and production-speed testing, makes the instrument versatile across R&D and manufacturing. Battery cell manufacturers use the 6365A/6367A for both incoming cell characterization and outgoing quality verification on the production line.

Applications

Battery cell manufacturers, fuel cell membrane researchers, supercapacitor producers, corrosion engineers, and electrochemical sensor developers all benefit from the 6365A/6367A’s ultra-low frequency reach. As India’s battery and EV manufacturing sector expands, this instrument addresses a critical measurement gap for quality-conscious Indian manufacturers.
