Hamilton Co. has introduced the Polylite Plus ORP (oxidation-reduction potential) sensor, which are part of the company's Arc technology line. The new sensors feature the company's proprietary Polisolve electrolyte, which is stable to most organic solvents, even in harsh environments. These robust sensors deliver reproducible measurements and are ideal for high-pressure water, wastewater and chemical applications. They can be steam-sterilized, autoclaved or cleaned in place. The sensors communicate directly with the process control system, with both analog 4-20 mA and digital Modbus interfaces.Hamilton Co.www.hamiltoncompany.com
