A lanyard is included for convenient and secure use of the Salt20 Salinity Tester.
The complete test kit comes in a rugged carrying case for protection and portability.
Setup
Battery Installation
The Salt20 Salinity Tester is powered by 4 AAA batteries.
- Unscrew the battery cap at the top of the meter.
- Insert the AAA batteries according to the polarity indicators (+/-).
- Securely screw the battery cap back on to ensure the waterproof seal.
Initial Preparation
- Remove the protective cap from the sensor.
- Rinse the sensor with distilled water and gently shake off excess water.
- The meter is now ready for calibration or measurement.
Operating Instructions
Basic Measurement
- Turn On: Short press the MEAS button to turn on the meter.
- Immerse Sensor: Dip the sensor into the sample solution, ensuring the solution covers the sensor completely. Stir gently to remove air bubbles.
- Read Measurement: Wait for the smiley face icon to appear and remain stable on the LCD, indicating a stable reading. Record the salinity (ppt) and temperature (°C/°F) values.
- Turn Off: Long press the MEAS button to turn off the meter.
Switching Units
To switch between °C and °F, with the meter turned off, long press the CAL button until the unit changes.

Calibration
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.
- Prepare Solution: Pour a small amount of the 12.88 mS/cm (6.44 ppt) calibration solution into a clean beaker.
- Enter Calibration Mode: With the meter turned on, short press the CAL button. The display will show "CAL" and the calibration value.
- Immerse Sensor: Dip the sensor into the calibration solution. Stir gently.
- Wait for Stability: The meter will automatically recognize the calibration solution. Wait for the smiley face icon to appear and remain stable. The calibration success symbol (M) will also appear.
- Exit Calibration: Short press the MEAS button to exit calibration mode and return to measurement mode.
Note: Always use fresh calibration solution for each calibration. Do not pour used solution back into the bottle.
Maintenance
Sensor Cleaning
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.
- Never wipe the sensor with abrasive materials or apply excessive force, as this can damage the platinum black coating.
Storage
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.
Troubleshooting
Common Issues and Solutions
| Issue | Possible Cause | Solution |
|---|---|---|
| Inaccurate Readings | Sensor dirty; Calibration needed; Expired calibration solution | Clean sensor; Perform calibration; Use fresh calibration solution |
| No Display / Meter Won't Turn On | Dead batteries; Incorrect battery installation | Replace batteries; Check battery polarity |
| "Out-of-Range" Warning | Salinity level exceeds 10.0 ppt | The meter's range is 0-10.0 ppt. For higher ranges, a different meter is required. |
| Slow Response | Sensor needs cleaning | Clean the sensor thoroughly |
