IntelliCAL™ CDC401 is a digital, graphite, 4-pole conductivity probe. The probe is available in either a standard or a rugged version.

• Compatible with digital Hach meters only (e.g. HQd meters)
• Provide ultimate traceability in measurement history
• Probes alert the user when re-calibration is needed
• Probes can be moved between meters without the need to re-calibrate or re-enter measurement settings
• Rugged probes can reliably measure conductivity in the harshest environmental conditions; waterproof up to 3 m for 24 hours (IP 68 rating)

The CDC401 is ideal for measuring electrical conductivity, salinity, resistivity, or total dissolved solids (TDS) in wastewater, drinking water, or general water quality applications.

Conductivity: 0.01 to 200 mS/cm

TDS: 0 to 50000 mg/L as NaCl

Salinity: 0 to 42 g/kg or %

Resistivity: 2.5 to 49 MΩcm
