TDS (Total Dissolved Solids) meters provide a measurement of all
solids dissolved in the water. This provides a measurement to
determine water quality and monitor the effectiveness of RO and DI
The HM EZ TDS meter is a great tester at a economical price. Large
display with TDS reading and auto off function
Tips for using a TDS meter:
Avoid touching and do not damage the electrodes
Keep the electrodes clean by rinsing them in RO water, if scale
builds up on the electrodes you can use a little vinegar to clean
them, rinse well in RO water after cleaning.
Don’t worry if the RO unit’s effluent tds is between 0-5, the water
is usually pure enough to use for aquatics, running the RO units
for five minutes usually results in a drop in TDS after initial
start up, flushing the membrane will also help bring down initial
If you find your Tap water TDS is high and this results in a value
of over 5ppm (parts per million) TDS in your product water install
a D-D Di pod for complete removal of positive and negatively
charged ions. Monitor the RO output at least once a week to
evaluate when the Di resin requires changing out.
Always use a clean collection vessel that is well rinsed before
collecting water for testing. Minute amounts of detergent can give
false high TDS readings.
Do not attempt to read the TDS of salt water for use in reef
aquaria, the salt concentration will be off the scale and won’t
provide any useful reading.
So to sum up a TDS meter is a cheap and invaluable tool for keeping
tabs on fresh water quality both before and after Reverse osmosis
Total Dissolved Solids (TDS) are the total amount of mobile charged
ions, including minerals, salts or metals dissolved in a given
volume of water, expressed in units of mg per unit volume of water
(mg/L), also referred to as parts per million (ppm). TDS is
directly related to the purity of water and the quality of water
purification systems and affects everything that consumes, lives
in, or uses water, whether organic or inorganic, whether for better
or for worse.
The EPA Secondary Regulations advise a maximum contamination level
(MCL) of 500mg/liter (500 parts per million (ppm)) for TDS.
Numerous water supplies exceed this level. When TDS levels exceed
1000mg/L it is generally considered unfit for human consumption. A
high level of TDS is an indicator of potential concerns, and
warrants further investigation. Most often, high levels of TDS are
caused by the presence of potassium, chlorides and sodium. These
ions have little or no short-term effects, but toxic ions (lead
arsenic, cadmium, nitrate and others) may also be dissolved in the
Even the best water purification systems on the market require
monitoring for TDS to ensure the filters and/or membranes are
effectively removing unwanted particles and bacteria from your
