Overview of Hach CDC40103 Conductivity Electrode
The CDC40103 is a standard Intellical series conductivity electrode manufactured by HACH (USA), with a 3-meter cable. Designed for laboratory use, it can measure conductivity, salinity, resistivity, and total dissolved solids (TDS) in wastewater, drinking water, and general water quality. Used with HQ series meters, it provides accurate and stable measurement results.
Core Functions and Advantages
Intelligent Calibration Management
Each Intellical electrode independently stores calibration history and settings. When replacing electrodes, there is no need to re-enter parameters, greatly reducing calibration workload. The meter automatically recognizes the probe and reads historical information, minimizing human error.
Ready to Use
Calibrated at the factory, it is ready to use out of the box. If the electrode needs recalibration, the meter proactively reminds the user, ensuring reliable measurements at all times.
Waterproof and Durable
The standard electrode is waterproof for 24 hours at a depth of 3 meters (liquid-filled electrodes must not be immersed in deep water). Rugged electrodes offer longer cables to suit different field requirements.
Model and Selection Guide
Hach conductivity electrodes are available in standard and rugged types with various cable lengths to meet diverse application scenarios.
| Type | Model | Cable Length | Application |
|---|---|---|---|
| Standard | CDC40101 | 1 m | Routine laboratory measurement |
| Standard | CDC40103 | 3 m | Laboratory and light field use |
| Rugged | CDC40105 | 5 m | Field and harsh environments |
| Rugged | CDC40110 | 10 m | Deep water or remote measurement |
| Rugged | CDC40115 | 15 m | Deep water or remote measurement |
| Rugged | CDC40130 | 30 m | Deep water or remote measurement |
Compatible Meters and Kits
The CDC40103 can be flexibly paired with Hach HQ series portable meters. Common kit configurations include:
- HQ30d53203000: HQ30d meter + CDC40103 standard conductivity electrode (3 m cable)
- HQ30d53201000: HQ30d meter + CDC40101 standard conductivity electrode (1 m cable)
- HQ30d53215000: HQ30d meter + CDC40105 impact-resistant conductivity electrode (5 m cable)
- HQ30d53103203: HQ30d meter + PHC10103 pH electrode (3 m) + CDC40103 conductivity electrode (3 m)
In addition, HQ meters automatically recognize Intellical smart probes, retain calibration history, reduce setup time, and ensure accurate data even in challenging samples or environments.
Usage and Maintenance Recommendations
- Before first use, inspect the electrode for damage.
- Connect the electrode to the HQ meter; the instrument automatically recognizes it and reads the calibration history.
- If calibration is prompted, follow the on-screen instructions to calibrate with standard solutions.
- After measurement, rinse the electrode with deionized water to avoid cross-contamination.
- For long-term storage, keep the electrode in dedicated storage solution.
Following these steps can extend electrode life and maintain measurement accuracy. For more information, consult a Hach expert or refer to the product manual.
