HI-6321 Advanced Conductivity Benchtop Meter
HI-6321 Advanced Conductivity Benchtop Meter
The HI-6321 Advanced Conductivity Benchtop Meter from GAPS Water Treatment is the laboratory solution for high-precision water quality analysis, blending modern design with advanced technology for repeatable, reliable results. Built for demanding lab environments, it boasts a practical footprint, an intuitive, glove-compatible capacitive touchscreen, and a flexible electrode arm configurable on either side to maximize space and convenience.
Practical, Streamlined Laboratory Design
The HI-6321 is part of Hanna's HI-6000 series, engineered to meet the needs of today’s laboratories. Its large, easy-to-use interface accelerates workflow, while the compact design ensures it fits seamlessly into any lab. A dedicated electrode holder is included, mountable to either side, so you enjoy maximum flexibility for setup without sacrificing stability or convenience.
Supplied with Advanced Four-Ring Probe
This benchtop meter is supplied with the HI-7631233 four-ring probe, enabling measurements of conductivity (μS/cm, mS/cm), resistivity (Ω·cm, kΩ·cm, MΩ·cm), TDS (ppm, ppt), and salinity (ppt, PSU, %). The integrated temperature sensor supports automatic temperature compensation, ensuring accurate results across a full range of lab applications. This robust, purpose-built probe requires infrequent calibration and covers an extensive measurement range for critical water quality parameters.
The HI-7631233 probe uses three specialized compensation algorithms:
- Linear: For measurements where the temperature coefficient of variation is consistent.
- Standard: Ideal for high-purity water and resistivity readings above 1 MΩ·cm.
- Natural: For measurements of natural waters (well, ground, or surface) following ISO 7888.
Complete Range of Measurement Units
- TDS: Both calculated (factor x EC25) and EC-to-ppm conversion for broad reporting needs.
- Salinity PSU: Measures practical salinity of seawater for standard reference conditions.
- Salinity PPT: Uses the Natural Seawater Scale for applications between 0.00 to 80.00 g/L.
- Salinity %: 100% salinity ~ 10% solids, for versatile reporting.
