Exploring Types of Color Sensors for Liquid Color Detection

Liquid color detection can be challenging without the right equipment. Whether you need to obtain color data to ensure your liquids meet precise tolerances or you want to gain a threshold for a certain amount of contamination within the liquid, finding equipment that can deliver rapid and accurate results is key. It’s especially important to understand what types of color sensors will be compatible with the type of liquid you’re using and its opacity level. 

At EMX, we’ve designed two high-quality industrial sensors to support liquid color detection, each of which offers an array of unique advantages. Read on to learn more about these standout solutions — the ColorMax VIEW and the OPAX — and discover which is best for your needs.

Exploring Two Types of Color Sensors 

ColorMax VIEW

The ColorMax VIEW offers high-speed readings and reliable measurements of translucent materials, from glass to plastics, films, and more. Its patented technology is field-proven to ensure it offers maximum performance for a wide variety of applications and allows users to maintain tight control of the colors of their materials. As a through-beam sensor, it shines a light through the liquid from the outside of the transparent vessel storing the sample. As long as the liquid is not too opaque, the readings will be rapid and accurate.

For liquid color detection, it offers extremely precise color analysis with RGB values. This highly versatile equipment can be set with thresholds to ensure your samples fall within the precise tolerance range or you can retrieve exact analog values if you opt not to use its yes/no outputs. If you’re debating between types of color sensors, this option is an ideal match for applications that demand a specific color value.

The ColorMax VIEW is also available in a streamlined kit that allows you to get your equipment up and running even faster. For accurate and precise color detection of liquids that can keep up with high-speed production needs, turn to this quality sensor. 


This unique through-beam sensor measures opacity and was designed to deliver the ultimate on-the-line performance by shooting a line of light through a mostly transparent sample and measuring how much contamination is suspended in the liquid. Because it uses infrared light, it’s compatible with a wider range of liquids and can offer readings for those ranging in transparency. Still, liquids that are too opaque will cause the sensor to fail or offer poor readings, but this choice is optimal if you have a slightly more opaque liquid you require color detection. Not sure if your sample will work? We offer free sample testing ahead of time to ensure our equipment will serve your needs before your purchase. 

The OPAX offers pass/fail criteria for color characteristics, meaning it will not provide the level of analog data its counterpart the ColorMax VIEW delivers. Still, it’s ideal for on-the-line measurement for real-time quality control, and it works rapidly to provide highly accurate results. It can even deliver high-speed detection with a response of only 100 microseconds. It’s adjustable and integrates well into existing production lines, making it a favorable choice for liquid color detection needs for a variety of industries.

The OPAX is ideal for applications seeking swift and streamlined color detection from mostly transparent liquids, and it offers enhanced flexibility in the samples it can accurately measure. Purchase it in a convenient kit to get it up and operating more quickly and start leveraging its benefits without delay. 

Choosing Between Types of Color Sensors

Choosing between these two powerful types of color sensors is made easy when you evaluate a handful of key factors. 

  • Do you need definitive color data? If you require the exact color data, choose the ColorMax VIEW, which provides analog data readings. Only need to ensure it fits within a certain threshold? Consider the OPAX instead. 
  • How transparent are your liquids? Both sensors demand liquid that’s transparent enough for the beam of light to go through without hindrance, but the OPAX offers extended flexibility in the types of liquids it can accurately measure. When in doubt, turn to the EMX team for support and send a sample for us to review.
  • Do you need accurate and efficient results? Both pieces of equipment are ready to deliver. Count on these sensors to keep up with your busy production line and offer real-time control of the factors impacting your color threshold compliance. 
  • Do you need to submerge your sensor in liquid? Both of these sensors require external testing. It’s important to ensure you store your liquid sample in a transparent container that the light of the sensor can pass through without difficulty. Neither piece of equipment can be submerged in the liquid for readings.
