The resistivity of water is a measure of the ability of water to resist electric current. Pure water has a resistivity of 18.104 milliohms (mΩ) at standard sea-level atmospheric pressure. Resistivity is not constant, but varies depending on temperature and the presence of solutes that may be electrolytes. The resistivity of water is one of the parameters used to determine the quality of a water source. The higher the resistance, the more are the contaminants in the water. In other words, high resistivity is a sign that there are either high levels of dissolved solids or contaminants like metal or grime.
Monitoring the water purity is a necessity for power generation, semiconductor manufacturing and other industries. The so-called resistivity meters rightly serve this purpose as they can be used to measure the quality of raw water, in-line with treatment plant process control, and after treatment. At Cannon Water Technology, we offer an extensive line of water resistivity meters that offer a relatively inexpensive way to measure water quality. When you opt to buy resistivity meter online, you get a chance to explore a wide variety of models and choose a one that best suits your requirements at a cost-effective price.
Working of Water Resistivity Meter
Water resistivity meter is a sophisticated device that measures the electrical properties of water and determines if it is pure or not. The device shows the presence of pollutants, and other physical or chemical impurities.
A water resistivity meter is made up of a transmitter, a receiver and an electronic circuit. The transmitter sends a current into the measuring cell through the transmitter wire. This current goes into the measuring cell and through the area that needs to be tested. The meter has a sensor that produces an electrical impulse and sends it to the water sample. A display then shows the amount of current that returns to the meter from the water sample. The information gathered is then used to determine the resistivity level of the water.
Beneficial Features of Resistivity Meters
Water resistivity meters are an effective and economical way to test water quality. They are great for homeowners and businesses alike, and can be used to perform a wide range of tests. A few amongst the well-known features of this tool offered by us are as follows:
- This digital water resistivity meter has a clear 4 digit liquid crystal display, which allows easy reading in outdoors as well as in low-lit areas with the backlight.
- This hand-held device can be used for both indoor and outdoor use.
- No wires need to be inserted into the water stream or soil, which could potentially interrupt or change the natural balance of minerals present in the water.
- It is IP67/NEMA 6 Waterproof to 1 meter/3 feet rated.
- The device is waterproof and can be fully immersed to 3 feet/1 meter.
- The unit is manufactured with long life internal electrodes.
- It is supplied complete with all accessories to perform the measurement.
- Water resistivity meter comes with thermoformed carrying case.
Applications of Resistivity Meters
The resistivity meter can be used to determine the concentration of suspended solids in water, testing groundwater, checking for contamination from landfill leachate, investigating contamination in lakes, rivers and tidal estuaries. Additionally, it is often used in the fields of geophysics and hydrology for ground water exploration, groundwater level monitoring and detection of groundwater pollution.
