Q. How do I use the TDS meter or indicator?

Q. Does the TDS Meter measure lead levels?
A. No, the meter measures Total Dissolved Solids and is not intended to measure lead levels.

Q. What is the meter reading?
A. The TDS meter included provides a reading of total dissolved solids in Parts Per Million, ppm.


Q. What are total dissolved solids?
A. Total Dissolved Solids (TDS) are non-organic impurities found in water, which contribute to a difference in the taste of water. Dissolved solids enter our water supply through old piping, run-off from road salts, pesticides, fertilizers and more.

Q. Is it bad to remove all TDS?
A. Todays filtering technologies cannot discriminate between bad chemicals and good minerals that could be present in the water, the filter removes all of these, therefore it is important to follow a diet that provides these essential minerals that the body needs. Many nutritionist recommend drinking purified water with a meal and not in an empty stomach.

Q. How often should I measure the TDS level in my water?
A. The TDS meter that comes with your system is provided so that you can measure your TDS on an ongoing basis - perhaps every other day. This is especially important if you have high TDS water (over 300), as your filter will need to be changed more often. By using the TDS meter to frequently measure your filtered water, you will know it is time for a filter change before it has gone too far past 006

Q. What type of batteries does the meter use?
A. They take either 2 - 357A, 2-LR44 or 3-AG3 batteries which can be found anywhere you would buy a watch battery.

Q. What can't the meter detect?
A. The meter cannot detect uncharged particles such as organic contaminants. It also cannot detect undissolved particles such as bacteria.

Q. Why is my TDS Meter/Indicator not working?
A. As with any electronic device, sometimes you may encounter issues with the TDS meter.

Please follow the steps below to resolve your issue.

1. Did you remove the cap? (Applicable for digital only)
2. Have you turned it on? (Applicable for digital only)
3. Have you been storing it in the fridge? If so, sometimes you need to allow it warm up
to room temperature so that it can function properly. If you have already done that, check to be sure it hasn't shorted out due to water contact.

4. Please check the LCD screen to see if you see rust. If rust is present you will need to replace the TDS meter.

5. If nothing else is wrong, the battery is probably dead. To replace the battery, remove the end of the TDS and replace with a new 357-A battery that you can buy anywhere you get a watch battery.

Q. Do TDS levels change in hot or cold water from the same tap?
A. TDS levels change in hot or cold water from the same tap because containments dissolve easily in warmer water which leads to a higher reading. The TDS meter corrects for temperature, but if the water is too hot it will give artificially high values. In general, the most accurate reading will be at or near room temperature.
