The GREENLIGHT™ continuous concentration monitor is a completely self-contained measurement system. Its small, modular design enables easy, reliable and low-cost continuous monitoring of fluid concentration using state-of-the art refractive index sensor technology with a user-friendly interface. The ACTS™ fluid monitor and control system is a fully integrated system that measures pH, temperature, conductivity or other fluid properties in addition to concentration via refractive index. It provides automatic concentration control capability by independently controlling six separate programmable relay outputs for additions of water, fluid concentrates or additives.
