Chlorine Meter

Chlorine Meter

Chlorine is a chemical used for disinfecting water. Chlorination is a process of adding chlorine to water to disinfect it and kill any harmful bacteria or pathogens that may be present. While chlorine is effective at disinfecting water, it can also be harmful to human health if consumed in large amounts. In other words, the ideal amount of chlorine in drinking water should be regulated to ensure public health and safety. To better monitor these levels, a chlorine level meter/ portable DPD Colorimeter is often used. By using this device, individuals in charge of public water systems can accurately measure the appropriate amount of chlorine needed for safe consumption.

At Cannon Water Technologies, we offer several models of chlorine tester level meter to serve the purpose. Our selection features various types of chlorine level meters, including portable chlorine meters. All these chlorine testers can be held in hands and feature digital displays, which allow users to check the chlorine levels in a given sample.

Steps Involved in Chlorination

The process of chlorination encompasses several steps that guarantee the efficacious removal of harmful viruses, bacteria, and other microorganisms. Following are the major steps involved in the chlorine treatment process.

1. Pre-Treatment Assessment: Evaluating the water quality and understanding the required dosage of chlorine is the first step in the chlorine testing process. Here, testing the water sample for pH levels, turbidity, and the presence of contaminants is meticulously conducted by experts.

2. Chlorine Dosage Calculation: Now the appropriate dosage of chlorine is determined after pre-treatment assessment. Several factors including the type of microorganisms present in the water and the desired level of disinfection are considered before calculating the dosage.

3. Chlorine Preparation: The chlorine solution is prepared using chlorine tablets, chlorine gas, or liquid chlorine.

4. Disinfection: Adding the chlorine solution to the water at the desired level is the next crucial step. This chlorine solution may be added through bulk chlorination or continuous chlorination.

5. Contact Time: This is the resting period offered for the effective completion of disinfection. This allows chlorine to effectively react with microorganisms and neutralize them. The duration of the contact time can differ based on several factors like pH levels,, water temperature,  and the specific types of microorganisms present.

6. Residual Chlorine Testing: Once the required resting time has passed, residual chlorine levels are measured to ensure that the water is disinfected as expected. This can be done through field test kits or laboratory analysis.

7. Dechlorination: In certain cases, there may be a demand to remove excess chlorine from the water to prevent adverse effects on taste and odor. After this step, the disinfected water is ready for distribution.

Why Monitoring Chlorine Levels in Water is Absolute Necessity?

Monitoring chlorine levels in water using our range of chlorine measuring devices is necessary for various reasons and the following pointers will help you understand it better.

  • With regular monitoring of chlorine levels, water treatment professionals can ensure that water is free from harmful pathogens present in the water. This helps to curb the spread of diseases such as typhoid, dysentery, and cholera, which can cause severe health issues.
  • Chlorine serves as a residual disinfectant, effectively eliminating pathogens that may contaminate the water when passing through the pipes. By detecting any deficiencies in disinfection, water utilities can take necessary measures to address them, ensuring that safe and clean water reaches consumers' taps.
  • Another important aspect of monitoring chlorine levels is to prevent the formation of disinfection byproducts (DBPs). When chlorine reacts with organic matter in water, DBPs such as trihalomethanes (THMs) can be formed. These DBPs have an increased risk of cancer and other adverse effects. The water treatment plants can ensure that the appropriate amount of chlorine is added to minimize the formation of DBPs while still effectively disinfecting the water by carefully testing chlorine levels using a chlorine digital tester.

Benefits of Chlorination

Chlorination is an effective method of water treatment and has a number of benefits, which include: 

  • Chlorination is a safe and effective way to clean water, and is a relatively simple and inexpensive process.
  • It does not require any harmful chemicals and can be used to treat both large water supplies (such as a city’s water supply) and small water supplies (such as a swimming pool).
  • Chlorination prevents the spread of waterborne diseases by killing harmful bacteria in water. This is especially important in developing countries where access to clean water is limited.
  • Chlorine helps keep the pipes that transport fresh water clean. Over the time, pipes can become home to harmful bacteria if they are not properly cleaned and disinfected.
  • Chlorination can help to improve water quality by removing harmful bacteria and microorganisms. This process can also help to remove sediment and other particles from water, making it clearer and more enjoyable to drink.
  • Chlorination does not leave any residual taste or odor in the water. Once the chlorine has done its job of disinfecting the water, it breaks down into harmless byproducts that are quickly diluted in the water. You may be able to detect a slight chlorine smell in your water after it has been chlorinated, but this is not harmful and will quickly dissipate.

How Digital Chlorine Meters Work

Digital chlorine meters work on methods such as colorimetric, amperometric, and titration techniques. They use sensors and probes, which are immersed in the water sample that is being tested. These sensors are designed to detect the presence and concentration of free chlorine in the water. The meter's sensor consists of a specially coated electrode that acts as a catalyst in the electrochemical reaction that occurs between the chlorine in the water and the electrode. When the electrode comes into contact with the chlorine, it generates an electrical signal that is proportional to the amount of chlorine present in the sample. This electrical signal is then converted into a digital reading by the meter's internal circuitry. The digital display offers the user with a precise measurement of the chlorine levels depending on the unit of measurement chosen.

How Important is Regular Calibration and Proper Maintenance of Electronic Chlorine Tester

Periodic calibration and proper maintenance of handheld chlorine meter is important for the following reasons.

  • Accuracy: Regular calibration is essential to guarantee the accuracy and reliability of the readings provided by our range of chlorine measuring devices. This is especially critical in water treatment applications where public safety is of utmost important, such as in swimming pools, drinking water facilities, or industrial settings.
  • Compliance: Many industrial segments comply with strict regulations regarding water quality such as the food and beverage industry or the healthcare sector.  Regular calibration and maintenance of chlorine digital tester helps ensure that the water being tested meets these regulatory standards.
  • Data Integrity: Accurate and reliable data is extremely important when making important decisions pertaining to water treatment and quality control. A periodic calibration and maintenance of the chlorine measuring device help maintain data integrity by guaranteeing  that the readings obtained are consistent and precise.
  • Operational Efficiency: Properly calibrated and maintained handheld chlorine testers allows for faster and more efficient testing processes. By preventing errors and inaccuracies, businesses can streamline their operations, saving time and resources. This efficiency can be extremely beneficial for sectors that demand frequent or large-scale water testing.
  • Equipment Longevity: Electronic chlorine testers are expensive investments, and proper calibration and maintenance can certainly improve their operational lifespan. Regular calibration helps avoid inaccuracies and malfunctions, minimizing the need for costly repairs or replacements.
