Oakton (WD-35661-08) TDS Tester+ & EC Tester+ Sensor 08 Replacement electrode
The Oakton WD-35661-08 replacement electrode restores accurate readings to your TDSTestr+ and ECTestr+ meters when the original sensor degrades from extended use. This genuine Oakton sensor maintains the precision you rely on for conductivity and total dissolved solids testing in water quality applications.
SPECIFICATIONS
Electrode Details
| Model Number | WD-35661-08 |
| Manufacturer | Oakton |
| Sensor Type | Conductivity/TDS electrode |
| Compatible Meters | TDSTestr+ and ECTestr+ series |
| Design | Waterproof construction |
| Application | Water quality testing |
| Replacement Interval | As needed when readings drift |
INSTALLATION & USE
Electrode Replacement Process
- Remove the protective cap from the new Oakton WD-35661-08 sensor and inspect the electrode surface for damage or debris.
- Unscrew the worn electrode from your TDSTestr+ or ECTestr+ meter by turning counterclockwise, then hand-tighten the new sensor in place.
- Rinse the electrode with distilled water and calibrate your meter according to manufacturer specifications before taking measurements.
- Store the meter with the electrode immersed in storage solution or clean water when not in use to extend sensor life.
COMPATIBILITY
Meter Compatibility
This Oakton replacement electrode is engineered specifically for the TDSTestr+ and ECTestr+ waterproof handheld meters. It is not compatible with standard non-plus models or meters from other manufacturers. Verify your meter model before ordering to ensure proper fit and function.
🔧 Pro tip: Electrodes lose sensitivity over time from mineral buildup and general wear. If your readings seem inconsistent even after calibration, or if the sensor doesn't respond quickly when immersed in test solutions, it's time to replace the electrode rather than question your water quality results.
