Calibration Verification: Calibrate daily or before critical use using fresh calibration standards (1413 μS/cm or 12.85 mS/cm) appropriate for the expected measurement range .
Sample Compatibility: Rinse electrode thoroughly with distilled water between different samples to prevent cross-contamination. Ensure there are no air bubbles trapped on the electrode surface during measurement .
Battery Safety: Use only AAA alkaline batteries; do not mix old and new batteries; remove batteries for long-term storage to prevent leakage; dispose of used batteries properly.
Environmental Protection: Dispose of calibration standards, sample vials, and other consumables according to local environmental regulations. Calibration solutions contain salts and may be disposed of via standard laboratory waste streams.
Storage: Store the meter in its hard carrying case in a clean, dry environment. Protect from extreme temperatures and direct sunlight.
Training: Only trained laboratory personnel should operate the DEC1 for water quality testing applications.

Calibration Standard Exposure: If conductivity calibration standard (1408 μS/cm or 12.85 mS/cm KCl solution) splashes into eyes, flush with water for 15 minutes, seek medical attention; if on skin, wash with soap and water.
Sample Splash: If biological or chemical sample splashes into eyes, flush with water for 15 minutes, seek medical attention; if on skin, wash with soap and water.
Electrical Malfunction: If the meter shows signs of electrical malfunction (erratic readings, display issues, battery leakage), remove batteries immediately; do not attempt to operate; contact service personnel.
Electrode Damage: If the platinum sensing element is damaged, discontinue use; replace the electrode with a new DEC1-S combined probe.
