The Portable Conductivity Meter (BIO-0366) is a multi-parameter water quality analyzer designed for field and laboratory measurement of conductivity, resistivity, total dissolved solids (TDS), salinity, and temperature. This handheld instrument features a 7-inch touchscreen interface and stores up to 500 measurement groups, making it suitable for environmental monitoring, quality control, and analytical applications requiring portable water analysis capabilities.
The meter operates on a rechargeable 3.7V lithium battery and offers USB 2.0 connectivity with optional Bluetooth module for data transfer. Temperature compensation is provided with 0.1°C resolution and ±0.5°C accuracy in the 5-60°C range. The compact design (195×135×40mm, 600g) enables single-handed operation while maintaining laboratory-grade measurement precision for field applications.
How It Works
Conductivity measurement operates on the principle of electrical conductance through ionic solutions. The meter applies an alternating current between two electrodes immersed in the sample solution. Dissolved ions facilitate current flow, with conductivity directly proportional to the concentration of ionic species present. The instrument measures the resistance between electrodes and calculates conductivity as the reciprocal, expressed in siemens per unit length.
Temperature compensation algorithms correct conductivity values to a standard reference temperature, accounting for the temperature dependence of ionic mobility. The meter simultaneously calculates derived parameters including total dissolved solids (TDS) using established conversion factors, salinity through empirical relationships, and resistivity as the inverse of conductivity. The 7-inch touchscreen provides real-time display of all measured parameters with temperature-corrected values.

Practical Tips
Calibrate using standards that bracket your expected measurement range and perform multi-point calibration for optimal accuracy.
Why: Bracketing calibration ensures accurate interpolation across your working range.
Store the conductivity probe in appropriate conditioning solution between measurements and avoid prolonged exposure to air.
Why: Proper storage prevents electrode fouling and maintains stable measurement response.
Allow temperature equilibration between probe and sample before taking measurements, especially when moving between different temperature environments.
Why: Temperature equilibration ensures accurate temperature compensation and stable conductivity readings.
Rinse the probe with distilled water between samples of different conductivity levels to prevent cross-contamination.
Why: Cross-contamination can introduce measurement errors, particularly when moving from high to low conductivity samples.
If readings appear unstable, check for air bubbles around the probe electrodes and ensure adequate sample volume for complete probe immersion.
Why: Air bubbles and insufficient sample volume can cause erratic conductivity measurements.
Avoid measurements in corrosive solutions beyond the probe's chemical compatibility specifications.
Why: Chemical incompatibility can damage the probe and compromise measurement accuracy and safety.
Use the data storage feature to record measurement conditions and sample information along with conductivity values.
Why: Complete documentation enables traceability and facilitates data interpretation during analysis.
Verify calibration periodically using certified reference standards, especially when measurement accuracy is critical.
Why: Regular calibration verification ensures continued measurement reliability over time.
