Oakton (WD-35661-17) TDS Tester & EC Tester Sensor Replacement electrode
Oakton WD-35661-17 TDS Tester & EC Tester Sensor Replacement Electrode
Precision replacement sensor for maintaining accurate conductivity and total dissolved solids measurements in your Oakton handheld testers
Built for Field and Lab Reliability
OEM Precision
Factory-matched electrode ensures your Oakton microprocessor testers maintain calibration accuracy and measurement consistency over time
Waterproof Design
Sealed sensor construction pairs with waterproof Oakton tester housings for reliable operation in wet environments and field conditions
Dual Measurement
Single electrode measures both electrical conductivity (EC) and total dissolved solids (TDS) with automatic temperature compensation
Quick Swap
Simple threaded connection allows fast electrode replacement without recalibration tools or technical expertise
Designed for Oakton Handheld Testers
This WD-35661-17 replacement electrode is engineered specifically for Oakton waterproof microprocessor TDS and EC testers. Verify your meter model accepts threaded probe-style electrodes before ordering. Compatible with handheld units requiring conductivity and total dissolved solids measurement capability.
Electrode Service Schedule
Rinse and Store
Rinse electrode with distilled water and store in protective cap with a few drops of storage solution or tap water to prevent sensor dry-out
Calibration Check
Test against known conductivity standards and recalibrate meter if readings drift beyond acceptable tolerances for your application
Electrode Replacement
Replace sensor when calibration becomes unstable, response time slows, or readings fail to stabilize in standard solutions
Measurement Accuracy
Restore original factory performance to aging or damaged testers with genuine OEM sensor technology
Quality Assurance
Oakton factory specifications ensure compatibility with meter electronics and measurement algorithms
Lab and Field Use
Reliable performance across water treatment, aquaculture, hydroponics, and industrial process applications
