Hanna Instruments – HI2003 edge® Dedicated Conductivity/TDS/Salinity Meter

The HI2003 edge® Dedicated Conductivity/TDS/Salinity Meter is a slim, high-precision laboratory meter designed for accurate EC, TDS, salinity, and temperature measurements. It features a digital EC electrode with built-in microchip memory, automatically transferring calibration data upon connection. Supplied with the HI763100 four-ring platinum conductivity probe, it ensures wide measurement range with minimal polarization effects. With dual USB connectivity, wall or bench mounting options, and up to 1000 data logs, edge® delivers performance, flexibility, and space-saving design.

  • Digital Smart EC Electrode: Stores model, serial number, and calibration history
  • Four-Ring Platinum Probe: Wide range measurement with superior chemical resistance
  • Basic & Standard Modes: Simplified or fully customizable operation
  • Compact & Rechargeable: 8-hour battery life, zero-footprint wall mount option

Description

The HI2003 edge® Conductivity/TDS/Salinity Meter incorporates advanced digital EC electrode technology with an integrated microchip that stores calibration information directly in the probe. Model number, serial number, calibration standards used, and date/time of the last calibration are automatically recognized by the meter when connected via the 3.5 mm probe input, ensuring fast setup without alignment issues or pin damage. Included with the meter is the HI763100 four-ring platinum conductivity probe, which features an integrated temperature sensor for automatic temperature compensation. Compared to traditional two-pole probes, the four-ring design provides a broader measurement range and significantly reduces polarization effects. The probe’s glass and PVDF body with a PEI sleeve offers exceptional resistance to corrosive substances.

Designed for adaptability, edge® can be wall-mounted to eliminate benchtop footprint or placed in a tabletop cradle with an adjustable swivel electrode holder for optimal viewing and charging. The meter supports manual, stability, and interval logging (up to 1000 records) with GLP data storage. Users can operate in Basic Mode for simplified automatic functions or switch to Standard Mode to customize temperature correction coefficients, interval logging, and calibration settings. With dual USB ports for charging, PC connectivity, and flash drive storage, the HI2003 is ideal for laboratory and industrial conductivity applications
