1-Point Auto Calibration
The Salt20 Salinity Tester uses a 1-point auto calibration process with auto buffer recognition. It is recommended to calibrate the meter regularly for accurate results, especially before critical measurements or if the meter has not been used for a long time.

The Salt20 Salinity Tester features effortless single-button auto calibration with auto buffer recognition, simplifying the calibration process.

באַמערקונג: Always use fresh calibration solution for each calibration. Do not pour used solution back into the bottle.
וישאַלט
סענסאָר רייניקונג
The BPB (Brush-Resistant Platinum Black) sensor is robust but requires proper cleaning to maintain accuracy.
- After each use, rinse the sensor thoroughly with distilled or deionized water.
- If there is visible contamination, gently brush the sensor with a soft brush (like a soft toothbrush) while rinsing.
- For stubborn deposits, soak the sensor in a mild detergent solution for 10-15 minutes, then rinse thoroughly.
- קיינמאָל wipe the sensor with abrasive materials or apply excessive force, as this can damage the platinum black coating.
סטאָרידזש
For long-term storage, ensure the sensor is clean and dry. Replace the protective cap. Store the meter in its carrying case in a cool, dry place.
