Signet 5800CR Conductivity Monitor
Member of the ProPointTM Family of Monitors
Analog and Digital Display
Description
The Signet 5800 ProPointTM Conductivity Monitor features a unique analog/
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 analog
dial serves as a quick, at-a-glance
indicator of the measurement process.
The 5800CR offers 2 fully programmable dry contact relays and a 4 to 20mA
current. The monitor requires 12 to
24 VAC or VDC and is packaged in a
convenient 1/4 DIN, NEMA 4X/IP65
front panel. The enclosure is hardcoated, high-impact, UV resistant
polycarbonate.
In addition to programmable outputs
and relays, the unit can also be set up
to measure raw conductivity values,
hence meeting USP requirements.
