摘要：

This paper presents a new methodology of analyzing liquid conductivity via the Hall Effect sensor based on electrochemical properties. Two different magnetic field cores with the sane coil length (10 m, AWG 31) were studied. namely ferrite solenoid cores and toroidal iron powder cotes (T131-26). The magnetic field generated by both type of cores was then used to generate a Hall voltage with the cores ratios of 1:1. The output Hall voltage is, in turn, sent through a microcontroller. together with a 10 bit converter for real time data analysis. The magnetic-field density of the solenoid for analyzing the conductivity of brine is 31 mT for solenoid, and 10.74 mT for toroid cores. respectively. Results from other materials arc compared to the reference conductivity of salt sol ton which amounts to 16.211 mS/cm when assessed with the solenoid core, and 16.406 mS/cm when assessed with the mid core.
