Conductivity Meters (EC)

The conductivity of a fluid or a solution is the quantification of its ability to conduct or transmit electricity. It precisely depends upon the density of ions in the fluid and is directly proportional to the same. Conductivity is measured in Siemens per meter, and conductivity meters are the tools used to measure it. It checks the flow of electric current in a solution by connecting to the sensor which is immersed in the fluid. Conductivity meters find applications across industries where good conductor fluids or water bodies need to be tested and controlled.

There are various conductivity meter brands available at Cannon Water Technology, such as HM Digital and Myron L. We are well-known suppliers of good-quality conductivity meters and experts in supplying various types of water treatment equipment made by reputed brands.

Working Principle of Electrical Conductivity Meters

Electrical conductivity testers work based on the electrical conductance of ions in a solution or fluid and how this factor impacts the flow and other features of electric current. The ions or charged atoms carry the electric current through the solution. A high density of ions leads to high conductivity and hence a high transmission rate of electric current. There are some applications that may require high conductance, while others may require low conductance that can be converted to resistivity. Water treatment is one such application, where electrical conductance must be in normal and acceptable ranges. By and large, electrical conductivity measurement is important with regards to quality control of industrial processes.

Types of Conductivity Meters Available at Cannon Water Technology

Although most meters have all the options of measuring various parameters such as TDS, pH, and so on, here are a few generic types of conductivity meters that we offer:

  • EC Conductivity Meters: EC is nothing but a simple electrical conductivity meter. These are commonly used to check the amount of nutrients, contaminants, and salts in water usually for agricultural applications.
  • pH Conductivity Meters: These are either electronic or analog probes with both pH and conductivity measurement capabilities. The digital ones are modern sleek devices with a display and are water proof. Most of our pH hydrotesters are economical and with advanced microprocessor technology. They have one-point calibration and a wide temperature range.
  • Handheld Conductivity Meters: These are easy-to-handle almost pen like devices. In fact, Cannon Water offers an extremely handy pen-like device for this. It has advanced features including a microprocessor-based circuitry.
  • TDS Conductivity Meters: TDS stands for total dissolved solids in a solution or a liquid. Conductivity of a solution depends upon the amount of dissolved solids including salts present in it. It is measured with a TDS conductivity meter in parts per million. Most of them come with in-built temperature sensors and are chemical resistant.

Essential Components of an Electrical Conductivity Meter

These are the components that form an electrical conductivity tester.

  • Sensors: These comprise probes and temperature sensors. Most of the times, they are inbuilt. These temperature sensors not only sense the changes but auto adjust temperature and other settings as required. Auto adjustment of temperature compensates variations and enhances the accuracy in readings. Probes are sensors that are in direct contact with the solution. They have electrodes made of robust and conductive metals or alloys such as stainless steel.
  • Calibration and navigation controls: These controls are in form of push buttons. For navigation, the user interface may also be in the form of touch screen.
  • Circuit: The circuit applies voltage and actually measures the electrical conductivity of a solution.
  • Display screen:  A conductivity meter features a LCD display screen. They have multiple units for each parameter the meter measures. You can select the unit as per your preference.
  • Data storage options: Some models have data storage capabilities, which means they have internal memory to store the readings. Other models can be connected via USBs or Bluetooth to a computer or smartphone for data upload.
  • Housing or enclosure: Meters come with enclosures to prevent dust or contaminants from entering inside.
  • Power supplies and cables: You can connect these meters to an external electric socket via a cable. They can be powered by batteries as well. Cables are also needed to dip the probe into the solution, depending on the application.

Importance of Calibration in Ensuring Accurate Measurements

Calibrating any device after each or every few use is essential to maintain accuracy in measurements. The probes dipped in various solutions containing corrosive chemicals need cleaning. A fixed standard set point must be adjusted in any device to avoid errors and variations in readings, regardless of the parameter. Here are some pointers that depict why calibration and recalibration are important.

  • As mentioned, devices and equipment after continued use undergo wear and tear. This also happens due to environmental parameters, exposure to corrosive solutions, and more. Calibrating the instrument restores accuracy and extends the operational life.
  • Calibration is a crucial part of quality control as well as complying with industry standards and regulation.
  • Calibration of conductivity meters enhances the safety aspect in industrial environments, especially in applications where there is zero tolerance for errors due to inaccurate measurements. This prevents mishaps such as electrical hazards, shorting, and more.
  • Calibrating a conductivity meter leads to accurate measurements which saves costs, time, and energy consumption. Regular calibration as per the manufacturer’s guidelines reduces downtime and production processes.
  • Our digital electrical conductivity meters are quite easy to calibrate. They have a user-friendly menu to navigate after following the manufacturer’s calibration guidelines.

Maintenance of Digital Electrical Conductivity Meters

We offer digital electrical conductivity meters which are easy to maintain. However, a basic, periodic maintenance is crucial for any electrical or electronic instrument. Here are some tips to maintain digital ECs and extend their operating life.

  • First, the probes must be cleaned with distilled water after each use to avoid wear due to corrosive chemicals and prevent inaccuracies. If the sensor probe is heavily contaminated, you can consider using a mild soap solution for cleaning.
  • Use the right pH and buffer solution for calibration, and ensure the meter is recalibrated after each use.
  • Check the quality of electrodes and replace them if necessary. This is because they undergo wear over time. Ensure they are moist even when not in use.
  • Store the meter safely and away from direct heat and light when not in use.
  • If the electrical conductivity meter is battery powered, remove the batteries when not in use for an extended period.
  • Check for software updates and ensure the meter is upgraded.
  • Follow documentation process after each maintenance schedule.

How to Select the Right Electrical Conductivity Tester?

Here are some tips to select the right electrical conductivity meter based on your application.

  • Check your application requirements in terms of the upper and lower limits for temperature, pressure, type of solutions or water samples, such as with TDS, salinity, and so on, digital features, and more. Weigh these against the EC features.
  • If you need an EC tester for water, look for specific aspects of water sample or the water bodies from where it is collected. This gives an idea about the hardness, pH, salinity, TDS, turbidity, presence of chemicals and microorganisms, and other aspects. The measurement range can be defined based on all these parameters because this range would vary with each application.
  • Choosing the right sensor type or probe is important. Most probes have two to four electrodes. The latter offers a better level of accuracy.
  • There are meters designed to achieve tight tolerances and highly accurate output. If your application requires a high level of accuracy and precision, opt for these meters. Basically one needs to find out how much difference in accuracy of values is tolerable.
  • Look for a meter that has auto adjustment features to reduce temperature variations. This enhances accuracy of readings.
  • Check for data storage options, remote connectivity, inbuilt memory, and more. This is crucial in data analysis.
  • The display must be clear with a user-friendly interface. We offer digital displays with easy-to-navigate and intuitive controls.
