Water-Quality Combination Test Kits
Test for contaminants before installing water-treatment equipment such as boilers and filters. You can also check your pipes and equipment for improper chemical levels that can cause corrosion and scale buildup, shortening their life.
367-test kits include tests for six common water-quality parameters in boiler systems and cooling towers.
340-test kits include tests for monitoring municipal water, which is often treated with chlorine.
290-test kits include tests that help you monitor well water, which often contains sulfur compounds.

Water-Quality Test Kits
All the chemicals and labware you need for on-site sampling and water-quality testing.
Digital kits offer simpler and more accurate testing than analog kits. While analog kits require you to visually match color against a chart, these kits electronically measure color for you, even in dim lighting. The digital screen shows you a precise measurement.

Colorimeters
Ensure consistent coloring on products such as labels and packaging. The sensor on these colorimeters translates the light an object reflects to an exact color reading. Use them for quality control to prevent slight variation that you might miss with your eyes alone. Calibrate your colorimeter using the included white calibration block. The machine measures all other colors according to their variance from true white.
Color calibration plates (sold separately) test and calibrate your colorimeter. They include five colors across the color spectrum to give the device a reference point for exact color readings. Precisely manufactured to ISO/IEC 17025, these plates meet standards for testing and calibration equipment.

Color Calibration Plates for Colorimeters
Calibrate your colorimeter so it can identify colors with precision. The white block calibrates your colorimeter because the machine measures all other colors according to their variance from true white. The four colored blocks are particularly helpful in quality control applications, where you want to make sure a specific color is consistent unit-to-unit. Made of ceramic, these plates won’t degrade, warp, or discolor over time, ensuring reliable measurements. Their surfaces are smooth and easy to clean, so they resist scratches that could affect readings. These plates are precisely manufactured to ISO/IEC 17025 standards for testing and calibration equipment.

Photoelectric Color-Measuring Transmitters
Monitor the color of products as they pass by on your line. These transmitters don’t just detect if color is in mint condition—they also turn equipment on or off, all with a single device. They’re often used for quality control in printing and packaging lines. For instance, if ink runs low and causes a color’s hue to fade, they can send a signal to pause production. The photoelectric sensor uses a highly accurate LED beam that combines red, green, and blue (RGB), which detects the slightest shifts in color at high speeds. It can even sense gradual color changes on glossy and mirrored surfaces. Rated IP67, these transmitters are protected against dust and temporary submersion.
Transmitters with IO Link translate and send readings to control systems, such as computers, programmable logic controllers (PLCs), and human-machine interfaces (HMIs). This also lets you send commands from your control system to these transmitters. Since they have a PNP/NPN signal output, they automatically produce the type of signal output needed based on the device they’re connected to.
Cables with a socket (sold separately) connect transmitters to your control system or directly to compatible machinery.
