The Signet 5900 Salinity Monitor utilizes conductivity sensors to provide direct reading, including calibration, of salinity in parts per thousand (PPT). Equipped with a scalable 4 to 20 mA output and two programmable relays, the monitor requires 12 to 24 volts, ±10%, regulated, AC or DC, and is compatible with Signet 10 cm-1 or 20 cm-1 conductivity cells. Temperature is selectable for display in either °C or °F, and compensation is automatic. Calibration is simplified with single point salinity and temperature entry via the wet-cal menu sequence. The four button keypad arrangement with intuitive software design is user-friendly, and is offered with a hard-coated, high impact, and UV resistant polycarbonate front face. The front panel is rated NEMA 4X/ IP65 and an optional splash proof cover is available to protect the back of the instrument.
