The GF Signet 5900 salinity monitor utilizes conductivity sensors to provide direct reading, including calibration of salinity in parts per thousand (PPT). Equipped with a scaleable 4 to 20 mA output and two programmable relays, the GF Signet 5900 salinity monitor requires 12 to 24 Volts, AC or DC. In addition, the GF Signet 5900 salinity monitor is compatible with GF Signet 10 cm-1 or 20 cm-1 conductivity cells.

With the GF Signet 5900 salinity monitor, 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. Offered with a hard-coated, high impact, and UV resistant polycarbonate front face, the GF Signet 5900 salinity monitor's four-button keypad arrangement with intuitive software design is user-friendly. The front panel of the GF Signet 5900 salinity monitor is rated NEMA 4X/IP65.
