Ideal for all basic water testing applications. This meter test for levels of dissolved solids. "Dissolved solids" refer to any minerals, salts, metals, cations or anions dissolved in water. This includes anything present in water other than the pure water (H20) molecule and suspended solids. (Suspended solids are any particles/substances that are neither dissolved nor settled in the water, such as wood pulp.) Not all dissolved solids are bad (like calcium, magnesium and others) but higher levels in drinking water are associated with a lot of problems such as bad taste, hard water scale and toxic ions (lead arsenic, cadmium, nitrate and others) which may also be dissolved in the water. The EPA Secondary Regulations advise a maximum contamination level of 500mg/liter (500 parts per million (ppm)) for TDS.
This item is critical for system maintenance and problem solving. If you have a problem, the first thing Aquasafe will ask is "what are the TDS readings?" The TDS meter is the only way check to confirm that the RO membrane is working properly and at what efficiency. It is also the best way that you can tell when the DI filter (if you have one) is exhausted. We strongly recommend buying both PSI and TDS meters as they are absolutely essential in diagnosing problems, and confirming the system is operating as it was designed.
The TDS (Total Dissolved Solids) Meter of your system is extremely easy and intuitive to use and comes with its own set of intructions, but here is a quick tutorial. First you will need to get a small glass and rinse it of all dust or other particles. Now fill the rinsed glass with the water for which you would like to determine the TDS Reading (Total Dissolved Solids). Remove the cap from the bottom of the TDS Meter and turn on the meter. Now simply insert the portion of the TDS Meter that was covered by the cap into the glass of water. The number that shows on the digital display is the ppm count (Parts Per Million) of TDS (Total Dissolved Solids) in your water.
Note: Your TDS Meter has an auto shut off feature but try to remember to shut off the TDS Meter when you are done testing your water to save on batteries!
