Water Quality Monitor with Green & Red Indicator Lights Dual Port Digital Water Quality Monitor
  • The monitor has two sensors that will operate when it senses the difference of TDS between the supplied water and the purified water though the R/O membrane.
  • If the TDS does not drop to the desired rate while purifying the water, the red light will turn on and make a buzzing sound.
  • The water purifies can be purified with requiring rates defermined by the client. Commonly it is produced at the following range. High-5%, Med-15% , Low-35%.
  • The monitor can take measurement at two points with in & out probes, Usually at Feed inlet and Product outlet.
  • Easy installation.
  • Power is off automatically after 10 minutes of non-use.

bullet What is TDS?
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.
  • "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.)
  • In general, the total dissolved solids concentration is the sum of the cations (positively charged) and anions (negatively charged) ions in the water.
  • Parts per Million (ppm) is the weight-to-weight ratio of any ion to water.
  • A TDS meter is based on the electrical conductivity (EC) of water. Pure H20 has virtually zero conductivity. Conductivity is usually about 100 times the total cations or anions expressed as equivalents. TDS is calculated by converting the EC by a factor of 0.5 to 1.0 times the EC, depending upon the levels. Typically, the higher the level of EC, the higher the conversion factor to determine the TDS. NOTE - While a TDS meter is based on conductivity, TDS and conductivity are not the same thing. For more information on this topic, please see our FAQ page.
 
bullet Why Should You Measure the TDS Level in Your Water?
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 water. 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 water.
Taste/Health High TDS results in undesirable taste which could be salty, bitter, or metallic. It could also indicate the presence of toxic minerals. The EPA's recommended maximum level of TDS in water is 500mg/L (500ppm).
 
Filter performance Test your water to make sure the reverse osmosis or other type of water filter or water purification system has a high rejection rate and know when to change your filter (or membrane) cartridges.
 
Hardness High TDS indicates Hard water, which causes scale buildup in pipes and valves, inhibiting performance.
 
Aquariums/Aquaculture A constant level of minerals is necessary for aquatic life. The water in an aquarium or tank should have the same levels of TDS and pH as the fish and reef's original habitat.
 
Hydroponics TDS is the best measurement of the nutrient concentration in a hydroponic solution.
 
Pools & Spas TDS levels must be monitored to prevent maintenance problems.
 
Commercial/Industrial High TDS levels could impede the functions of certain applications, such as boilers and cooling towers, food and water production and more.
 
Colloidal silver water TDS levels must be controlled prior to making colloidal silver.
 
Coffee & Food Service For a truly great cup of coffee, proper TDS levels must be maintained.
 
Car & Window Washing Have a washer with a spotless rinse? An inline dual TDS monitor will tell you when to change the filter cartridge or RO membrane.
