Can you measure with such liquids and conditions? We can overcome scattering with our unique digital imaging method and capture the 'true value' of liquid concentration.
No more confusion: The inline refractometer Polaris for liquid concentration measurement has steadily increased its track record of solving advanced challenges that astonish many industries, including chemicals, food, beverages, semiconductors, pharmaceuticals, and paper, with the response, "Can you really measure liquids and conditions like this?" 1. Not misled by bubbles or fine particles! = Digital image method 2. Less prone to deviation in indicated values! = Core optics seismic isolation structure 3. Strong against corrosive liquids! = Special material options for contact parts 4. High precision measurement & fast response! = Proximity design of temperature sensors and prisms 5. Almost no regular maintenance required! = Elimination of parts that need regular replacement 6. Compatible with a wide range of industrial applications! = Abundant connection format options The results include a reduction in cleaning water volume worth several million yen annually (with a payback period of 4 months), leading to improvements in quality and productivity, reductions in resource consumption, enhanced safety for workers, and reductions in workload and man-hours, ultimately contributing to solving more fundamental issues in production sites, such as "reducing environmental impact" and "addressing labor shortages."
