Patented 6th generation process refractometer for Kraft pulp mills – from true experts
KxS Retractable refractometer DCM-20 PASVE®
With KxS Technologies – the former K-Patents experts, customers trust our decades of expertise. KxS Retractable refractometer DCM-20 PASVE® is designed carrying forward the same deep pulp industry application knowledge.
The refractometer features the proprietary PASVE® isolation valve, an industry standard since the 1980s with over 75,000 units installed worldwide.
The DCM-20 PASVE® design provides secure connection to the process, maximum operator safety and simple, risk-free sensor insertion and removal without process shutdown.
The most maintenance-free pulp industry refractometer
KxS DCM-20 PASVE® is engineered to last longer than any other pulp industry refractometer without maintenance. It detects true buildup on prism, eliminating excessive prism washes and prism erosion, extending the equipment lifespan.
Optical stability like no other
The KxS DCM-20 PASVE® is built with advanced CMOS-based optics and 6th generation optical image recognition, meaning the signal noise ratio is very good. This leads to more precise and reliable measurement even in the most challenging applications.
Universal sensor for all applications
Our solutions are tailored to meet the specific measurement and safety requirements of each stage in the kraft chemical recovery and fiberline processes. No need for multiple models. All DCM-20 PASVE® sensors are interchangeable, covering the full R.I. range of 1.32…1.56 and all pulp mill dry solids content measurement applications up to
85 %.
