Water treatment is the process of conditioning and purifying water to increase its portability and utility for other purposes, such as irrigation, industrial use, recreational activities, and so on. However, purification and conditioning can be done only if the concentration of different solids in water is known. This concentration is measured using refractometers, which measure the refractive index of fluids.

Tips to Choose the Right Refractometer for Your Water Treatment Application

Choosing the right refractometer for water treatment isn’t easy and requires a comprehensive consideration of several factors. Here are a few key considerations that would help you make an informed decision:

  • Measurement Parameters: The first question is how you want to use the refractometer? For instance, you can use it to determine parameters like salinity, coolant concentration, dissolved solids, or sugar content in beverages. Hence, choose a refractometer that can accurately measure these desired parameter(s) in the required range.
  • Accuracy and Precision: Water treatment processes are complex and demand high accuracy at every phase. Hence, look for a refractometer that assures accuracy and precision. This would help you achieve reliable and consistent results, and ensure better quality control.
  • Measurement Range: What is the maximum and minimum measurement range of the parameter? Once you understand this, you must check if the device can measure these low and high concentrations, depending on your application requirements.
  • Temperature Compensation: The refractive index of the sample is affected by several factors and the temperature is one of them. Always ensure to choose a refractometer with temperature compensation (ATC). The feature adjusts the readings based on the sample's temperature, ensuring accurate results regardless of temperature variations.
  • Build Quality: Water treatment facilities are challenging work environments. They are laden with dust, debris, and moisture. Hence, focus on the build quality of these devices.  Focus on the material used in construction and ensure it is robust enough to withstand the environment in which it will be used.
  • Ease of Use: Refractometers are available in different designs. Always choose a refractometer that is user-friendly and easy to operate. It must possess an easy-to-follow display and intuitive controls or interfaces. This will facilitate efficient measurements and minimize errors.
  • Calibration and Maintenance: Focus on the calibration requirements of the refractometer. You can check on different reliable calibration options and their effectiveness. Although manufacturer sheets may contain this information, ensure the manufacturer assures technical support and guides you on calibration standards, and other factors that help optimize the value of your refractometer investments.
  • Reviews and Recommendations: As with all other water treatment devices and equipment, these refractometers are included in our collection after much consideration and research. Additionally, you can research them and read customer reviews. If you still have doubts, you can contact our water treatment experts, or seek recommendations.

FAQS on Refractometers

At Cannon Water Technology, we regularly process orders of refractometers. Although used in water treatment industries for several years, our experts still spend time answering their specific questions. This section includes some general and popular questions answered by our clients.

  • Are refractometers effective in water quality control?

Indeed, they are effective in water quality control. They provide information about the dissolved contaminants or solids in water. In water treatment facilities, the operators use refractive index measurements to identify deviations from desired levels. These measurements help them take appropriate measures to ensure the water quality remains within desired limits.

  • What are the benefits of using refractometers for coolant concentration analysis?

Our RT-100 Prism Inline Refractometers from Walchem are extensively used in analyzing concentrations of coolants like mono-propylene glycol and mono-ethylene glycol in closed loop monitoring systems. These devices measure the refractive index and provide data on the coolant-to-water ratio. This helps operators in water treatment facilities to maintain the optimal ratio of coolant-to-water to prevent corrosion and facilitate effective heat transfer in closed-loop monitoring systems. Sometimes, the readings of the refractive index also help operators to measure the effectiveness of the coolant.

  • Can I use these refractometers for measuring salinity in water?

Yes, you can use our refractometers for measuring salinity in water. The salts present in water will impact the refractive index. The salinity is often determined by comparing the refractive index of the water sample with the calibration curve or the known value.

  • Can refractometers be used to measure sugar content in beverages?

Yes, they can be used for sugar content measurement. RT-100 PRISM Inline Refractometers offered by us is used to measure the sugar content in a solution. These devices measure the refractive index of the liquid to indicate sugar concentration. The refractive index of a solution will increase for high sugar concentration. These increased values are referred to make necessary adjustments during the production process.

  • Do I need to take special precautions while using refractometers for water treatment?

Although our refractometers are designed for challenging work environments, it is always recommended to take certain precautions to optimize their performance in these environments. For instance, these devices would require regular calibration to ensure accurate readings. The samples must be handled carefully and the device must be operated to manufacturer's guidelines. Our inline refractometers assure automatic temperature compensation (ATC), accounting for temperature variations affecting readings.
