Are you tired of unreliable conductivity readings that compromise your water quality analysis or process control? Do you struggle with complex calibration procedures and difficult data management? The Hanna HI2003-02 edge® Conductivity Meter is the solution. Engineered by HANNA Instruments under strict ISO 9001:2015 standards, this state-of-the-art meter delivers unparalleled precision for measuring Conductivity (EC), Total Dissolved Solids (TDS), and Salinity. With its innovative smart probe technology, intuitive interface, and unique hybrid design that functions as both a benchtop and portable meter, the HI2003-02 empowers you to work with confidence and efficiency in any environment.

Why Choose the Hanna HI2003-02 edge® Conductivity Meter? Solving Accuracy, Usability & Data Management Challenges

Achieve reliable, reproducible results with intelligent features that directly address common pain points in analytical measurement.

• Eliminate Inaccurate Readings with Advanced Sensor Technology: Variability in temperature and probe condition can ruin measurement consistency. The included HI763100 digital four-ring platinum conductivity probe features a built-in temperature sensor for automatic temperature compensation. This, combined with the meter's ±1% of reading accuracy, ensures you get dependable, precise results every time, regardless of fluctuating sample conditions.

• Slash Calibration Time and Eliminate Errors: Recalibrating a meter every time you switch probes is tedious and prone to mistakes. The HI2003-02 edge® conductivity meter's smart probe technology stores its own calibration data directly on the probe. Simply plug in a probe, and the meter automatically recognizes it and applies the correct calibration—a true "plug-and-play" experience that saves valuable time in multi-user labs.

• Seamlessly Transition Between Benchtop and Field Work: Why buy separate instruments for the lab and the field? The innovative edge® design features a sleek, detachable meter (just 250 g) that nests securely in a benchtop docking station with an adjustable electrode holder. Use it as a stable benchtop unit for routine analysis, then detach it for portable, on-the-go measurements—versatility that solves the problem of needing multiple, less flexible devices.

• Ensure Data Integrity and Simplify Reporting: Manually recording readings is inefficient and risks transcription errors. The HI2003-02 precision EC meter logs up to 1000 records with Good Laboratory Practice (GLP) data for full traceability. Easily export your data to a PC via the micro USB port or directly to a flash drive using the standard USB port, streamlining reporting and ensuring compliance in regulated environments.
