This basic TDS & EC Digital Water Meter enables you to test the quality of various sources of water.
These meters are essential to a hydroponic grower to ensure your nutrients are the correct strength for each stage of your plant’s development.
It provides 1000 hours of continuous usage, which ensures you the best quality water. Suitable for drinking water, water filters, hydroponics, aquariums, food, coffee, pools, spa, etc.
The hold button is aimed at saving measurements for convenient reading and recording. It also has an auto-off function, which can turn off after 5 minutes of non-use to conserve batteries. It can be used in water purifiers and filters, food and drink quality monitoring, pools, and spas, aquariums, hydroponics.
How to calibrate your meter:
1. Press and hold the ON/OFF button to turn the meter on.
2. Hold down the shift button for 3 seconds, the temperature displayed on the LCD will now change to the ‘CALL’ word.
3. Release once this has changed and put the meter into the 1413 calibration solution.
4. Press the SHIFT button to increase the numerical value and use the hold button to decrease.
5.When your meter reaches its desired value press the SHIFT button again for 3 seconds and the ‘CALL’ word will change to ‘TEMP.’
6. Let’s go, your meter is calibrated.

Proper Usage / Storage
• Immerse the meter in the water/solution up to the maximum immersion level (2″).
• Lightly tap or stir the meter to remove any air bubbles.
– Pockets of air between the electrodes may interfere with the electrical current.
• Wait 10-20 seconds for the reading to stabilize.
– In hot (or ice cold) water, wait 20-30 seconds for the meter to compensate for temperature.
As the water temperature will adjust to room temperature, the reading will change to
accommodate the proper compensation.
• To ensure greater accuracy, turn the meter off and on for each reading.
• Shake any water off the meter after each use.
– This is to remove the droplets of water that may adhere to the surface between the
sensors and the housing around them. These drops may interfere with readings.
• Rinse in de-ionized water or other filtered water after use to ensure proper readings.
• The meter is not waterproof: Do not drop or submerge the unit in water.
• Do not store the unit in high temperature or direct sunlight.
