Conductivity/TDS Meter, Model # HI 2003, Hanna Instruments

Description

Conductivity / TDS Meter HI 2003 – Hanna Instruments

The HI 2003 Conductivity and TDS Meter from Hanna Instruments is a high-performance benchtop analyzer designed for precise measurement of electrical conductivity, total dissolved solids (TDS), salinity, and sodium chloride concentration in aqueous solutions. It is widely used in analytical laboratories, industrial water treatment facilities, environmental monitoring, and research applications where accuracy and measurement flexibility are critical.

This meter offers an exceptionally wide measurement range, allowing users to analyze everything from ultra-pure water to high-conductivity industrial samples. Automatic temperature compensation ensures reliable results across varying sample temperatures, while advanced calibration options provide excellent accuracy and repeatability. The instrument also allows user-selectable temperature correction coefficients and EC-to-TDS conversion factors, making it suitable for diverse industry standards and analytical requirements.

The HI 2003 supports multiple salinity scales, including % NaCl, PSU, and g/L, making it particularly useful for seawater analysis, food processing, aquaculture, and chemical manufacturing. When required, temperature compensation can be disabled to measure absolute conductivity, which is essential for certain research and quality control procedures.

Supplied with the HI763100 EC/temperature probe, the meter ensures stable measurements and long-term reliability. Its compact benchtop design, intuitive interface, and robust construction make the HI 2003 a dependable choice for both routine testing and advanced analytical work.
