TDS METER

Quality Conductivity meters for Reverse Osmosis and water treatment applications

 
 

 

 

Check TDS on demand 

One of the most accurate and versatile meters available in the market. Our battery operated "push to test " model will let you know if ppm readings on your RO system are within the range or is it time to change those filters? Preset or user adjustable setpoint and calibration provide  full control to the operator. Factory  calibrated with 50 and 100 mhos standard solutions.Built -in plumbing ,stainless steel  electrodes provide service free operation and compactability. Enclosure comes with mounting tabs for easy installation. Continous monitoring available as an option with a use of an AC adapter.

 Advantages 

1.Size and compactability. Built in plumbing and sensor do not need replacement or service.

2. No need for external power since it uses 9v standard battery which will last aprox 1yr or more.

3. Meter does have calibration and setpoint adjustment trimpots which will enable the user to set to any desired value within the range.

4. 3 1/2 digit display shows the conductivity value in micro siemens(mhos)

5. Can be mounted directly in between the plumbing or enclosure mounting tabs will let you install the meter on the wall with screws.

5.  John Guest quick connect fittings will make the installation a breeze.

90 day warranty:      If you are not happy , simply return it with full money back

Operation

Meter has two LED lights and a push button switch. When switch is pressed, it will light up either a Blue LED (good) or Yellow LED (service) depending on the setpoint setting. Default setting for the setpoint is 50ppm which is maximum desirable value for RO systems . Our meters are  calibrated with standard solutions and pass a 24hr plumbing check.

What is Conductivity?


 

Salinity and conductivity measure the water's ability to conduct electricity, which provides a measure of what is dissolved in water. In the SWMP data, a higher conductivity value indicates that there are more chemicals dissolved in the water.

Conductivity measures the water's ability to conduct electricity. It is the opposite of resistance. Pure, distilled water is a very poor conductor of electricity. When salts and other inorganic chemicals dissolve in water, they break into tiny, electrically charged particles called ions. Ions increase the water's ability to conduct electricity. Common ions in water that conduct electrical current include sodium, chloride, calcium, and magnesium. Because dissolved salts and other inorganic chemicals conduct electrical current, conductivity increases as salinity increases. Organic compounds, such as sugars, oils, and alcohols, do not form ions that conduct electricity.

Why is Conductivity Important?


 

Aquatic animals and plants are adapted for a certain range of salinity. Outside of this range, they will be negatively affected and may die. Some animals can handle high salinity, but not low salinity, while others can handle low salinity, but not high salinity.

In addition to its direct effects on aquatic life, salinity also has many other important effects on water chemistry and water density.

Many years ago, the water treatment industry adopted a nomenclature of PPM. Correlating PPM to microSiemens can be difficult, as water can be make up of different salt concentrations and dissolved metals, which can alter the conversion factor. It is preferable to use microSiemens as a unit of measure, however if you need to convert to PPM, here is a helpful link
