Q. What does the TDS meter do?
A. The TDS meter helps put a number on what your taste buds already tell you about what's in water. The higher the reading on the water, the more things dissolved in water. It shows the total number of detectable dissolved solids.

Q. How do I use the TDS meter?
A. It's easy! Push the "on" button, remove the cap and place about an inch deep into the water. Wait for the numbers to stabilize and see your final reading. Once you remove the TDS meter from the water the reading will go back to 000. Be sure not to place the TDS meter in water over an inch or two as the water may dampen the electronics and affect your readings.

Q. Why is the TDS meter important?
A. The tester empowers you to compare various water sources. If the number of your filtered water is above 006, it's time to replace your water filters.

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. Should I store the meter in the pitcher reservoir?
A. If you decide to store your meter in the reservoir, there are some things you need to do to keep the TDS meter in working condition. Make sure the white cap on the storage reservoir is completely sealed. When filling the pitcher, be careful not to get water into the storage compartment. Overfilling the pitcher reservoir may cause water to seep into the storage compartment.

Q. What type of batteries does the meter use?
A. They take 2 357A 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.
