The Pocket Conductivity Tester is a compact, handheld instrument designed for field and laboratory measurement of solution conductivity. This portable device measures electrical conductivity across multiple ranges with 0.1/1 μS/cm and 0.01 mS/cm resolution, providing researchers with rapid assessment of ionic content in aqueous samples. The instrument features single-point calibration capability and manual temperature compensation from 0-99.9°C for accurate measurements across varying environmental conditions.
With IP57 water resistance rating and battery operation, this tester enables conductivity measurements in diverse research settings including environmental field sampling, water quality monitoring, and laboratory solution preparation. The compact 185×50×20 mm form factor and 30-gram weight facilitate portability while maintaining ±1.5% full-scale accuracy for reliable quantitative analysis.
How It Works
Conductivity measurement relies on the principle that dissolved ionic species in solution conduct electrical current proportional to their concentration. The instrument applies a low-voltage alternating current between two electrodes immersed in the sample solution. Ionic species in solution facilitate current flow, with higher ion concentrations producing greater conductivity values.
The tester measures the electrical resistance between electrodes and calculates conductivity as the reciprocal of resistance, normalized for electrode geometry. Temperature compensation adjusts readings to account for the temperature dependence of ionic mobility, as conductivity typically increases 2-3% per degree Celsius. Manual temperature compensation allows users to input sample temperature for accurate conductivity determination across the 0-99.9°C range.
Multiple measurement ranges accommodate samples from low-conductivity purified water to high-ionic-strength solutions, with automatic range selection optimizing resolution and accuracy for each sample type.
