Hanna Four-ring EC/TDS Probe with Internal Temperature Sensor – HI76312

The Hanna HI76312 four-ring EC/TDS probe is designed for accurate measurement of conductivity and total dissolved solids (TDS) in laboratory and industrial water quality testing. Featuring platinum rings and a built-in temperature sensor, this probe compensates for temperature fluctuations, ensuring precise results in any environment. The polyetherimide (PEI) plastic body is highly resistant to chemicals, extending the probe’s lifetime and usability across various samples. With a 1 meter (3.3 ft) cable and robust construction, this probe serves as a direct replacement for HI5321, HI5521, and HI5522 meters.

• Platinum electrodes enable accurate EC/TDS readings in multiple ranges.
• Integrated temperature sensor ensures temperature-compensated results.
• PEI body offers excellent chemical resistance for laboratory and field applications.
• 1-meter cable allows flexibility and safe connection to compatible instruments.
• Optimized for laboratory, industrial, research, and water treatment operations.

The four-ring cell design is particularly advantageous for measurements in solutions with varying ionic strength, offering minimized polarization error compared to standard two-electrode cells. This makes the HI76312 probe suitable for a wide measurement range and critical quality assurance practices. Compatible with HI5321, HI5521, and HI5522 meters. Operating temperature range: -5 to 100°C (23 to 212°F). Cable length: 1 meter. Body material: polyetherimide (PEI).
