• Data Sheet - 5800CR Conductivity/Resistivity Monitor (pdf, 0.3 MB)

The Signet 5800CR ProPoint® Conductivity/Resistivity Monitor features a unique analogue/digital display, making it the preferred measurement instrument for applications requiring routine monitoring. The digital display guides the user through the simple menu system and provides precision information, while the analogue dial serves as a quick, at-a-glance indicator of the measurement process.

The 5800CR offers two fully programmable dry contact relays and a 4 to 20 mA current. The monitor requires 12 to 24 VAC or VDC ±10%, regulated and is packaged in a convenient 1/2 DIN, NEMA 4X/IP65 front panel. The enclosure is hard-coated, high-impact, UV resistant polycarbonate.

In addition to programmable outputs and relays, the unit can also be set up to measure raw conductivity values, meeting USP requirements.

5900 ProPoint® Salinity Monitor

• Data Sheet - 5900 Salinity Monitor (pdf, 0.3 MB)

The Signet 5900 Salinity Monitor utilises 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 monitor requires 12 to 24 volts, ±10%, regulated AC or DC, and can be used with Signet 10.0 cm-1 or 20.0 cm-1 conductivity cell constants. 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 splashproof cover is available to protect the back of the instrument.
