Overview
The Hanna HI2030 Edge² is a dual-mode, ultra-slim multiparameter meter engineered for high-reproducibility measurement of electrical conductivity (EC), total dissolved solids (TDS), salinity (in NaCl %, practical salinity units [PSU], and g/L), and temperature across laboratory, field, and industrial process applications. Unlike conventional single-function meters, the HI2030 Edge² integrates a precision four-ring platinum conductivity sensor with integrated Pt1000 temperature compensation and intelligent digital electrode architecture—enabling automatic electrode recognition, embedded calibration history storage, and real-time diagnostics. Its measurement principle relies on AC-driven four-electrode (tetrapolar) conductometry, eliminating polarization errors and contact resistance artifacts inherent in two- or three-electrode systems. This architecture ensures stable, drift-free readings across wide dynamic ranges—from ultrapure water (0.00 µS/cm) to saturated brines (500.0 mS/cm)—without manual range switching. The instrument operates in three physical configurations: handheld, benchtop (with adjustable rotating stand), and wall-mounted (via optional bracket), supporting ergonomic, space-efficient workflows in QC labs, aquaculture facilities, desalination plants, and environmental monitoring stations.
Key Features
- Four-ring platinum conductivity sensor (HI763100) with integrated Pt1000 RTD for fully automatic temperature compensation (0.00–6.00 %/°C selectable, default 1.90 %/°C)
- Digital electrode interface (3.5 mm proprietary connector) enabling plug-and-play recognition, firmware-assisted self-diagnostics, and secure data logging of calibration events and sensor health status
- 5.5-inch high-contrast LCD with 150° viewing angle and glare-resistant surface—optimized for wall-mount operation at up to 5 m distance
- Triple deployment flexibility: handheld portability (250 g), benchtop use with rotatable electrode holder, or fixed wall mounting for continuous batch monitoring
- Rechargeable lithium-ion battery with simultaneous charging and measurement capability via HI75110/220E USB power adapter
- Dual USB interface: USB-A for direct data export to FAT32-formatted USB drives; micro-USB for charging and bidirectional PC communication
- GLP-compliant data management with full metadata stamping (date/time, operator ID, electrode serial, calibration history, measurement mode)
Sample Compatibility & Compliance
The HI2030 Edge² is validated for aqueous matrices including drinking water, wastewater, seawater, brackish solutions, nutrient solutions, and industrial process streams. Its four-ring electrode design minimizes fouling and polarization effects in high-conductivity or viscous samples, while the PVDF body and PEI protective sleeve provide chemical resistance to acids, bases, and oxidants per ISO 17025-accredited handling protocols. The instrument supports compliance with ASTM D1125 (conductivity of water), ISO 7888 (electrical conductivity of water), and USP (water conductivity testing). When configured with user-defined operator accounts, audit trails, and electronic signatures, it meets foundational requirements for FDA 21 CFR Part 11 adherence in regulated pharmaceutical and food manufacturing environments. All stored data retain immutable timestamps and are exportable in CSV format for integration into LIMS or ELN platforms.
Software & Data Management
The HI2030 Edge² stores up to 1000 automatically logged measurements, 200 interval-sampled entries, and 600 manually triggered records—all tagged with GLP-mandated metadata. Data export requires no proprietary software: USB-A port enables direct drag-and-drop transfer to standard flash drives. For advanced analysis, the micro-USB port facilitates connection to Windows/macOS systems using Hanna’s free HI Connect software (v2.0+), which provides trend visualization, statistical summaries (mean, SD, RSD), calibration report generation, and batch export to Excel-compatible formats. All calibration events—including date, standard used, slope/mV offset, and electrode ID—are archived internally and retrievable on-screen or via export. Firmware updates are delivered via USB and support cryptographic signature verification to ensure integrity.
Applications
- Environmental monitoring: EC/TDS profiling of rivers, lakes, and estuaries; salinity tracking in coastal aquifers and marine ecosystems

- Pharmaceutical water systems: USP -compliant conductivity verification of Purified Water (PW) and Water for Injection (WFI) at multiple points-of-use
- Industrial cooling towers: Monitoring cycles of concentration, corrosion inhibitor dosing, and blowdown efficiency via EC drift analysis
- Academic teaching labs: Demonstrating ionic strength relationships, van’t Hoff factor determination, and temperature compensation models
FAQ
Does the HI2030 Edge² require manual range selection during measurement?
No. The four-ring electrode and adaptive auto-ranging circuitry enable seamless coverage from 0.00 µS/cm to 500.0 mS/cm without user intervention.
Can the HI763100 conductivity electrode be used for both EC and TDS measurements?
Yes. TDS is calculated in real time using the measured EC value and a configurable linear conversion factor (default 0.50; range 0.45–0.80), traceable to NIST-traceable KCl standards.
Is temperature compensation applied automatically during salinity measurement?
Yes. PSU and g/L salinity modes apply automatic temperature compensation using the built-in Pt1000 sensor; NaCl % mode uses fixed 25 °C reference unless compensated manually.
How is electrode calibration verified and documented?
Each calibration event is timestamped, logged with standard ID (e.g., “1413 µS/cm”), slope, offset, and electrode serial number—accessible via on-device menu or exported CSV file.
What is the expected service life of the HI763100 electrode under routine lab use?
With proper cleaning (HI70300 electrode cleaning solution) and storage in HI70300 storage solution, typical functional lifespan exceeds 24 months under daily QC use at ambient temperatures.
