The 873RS analyzer is an economical, basic, line-powered resistivity analyzer in a small form factor.
Each 873RS analyzer provides up to two resistivity sensor inputs, two analog output signals (one on plastic version) (4-20 mA, 0-10 V, 0-20 mA), and two alarm relays.
A choice of plastic, panel-mount or metal, field-mount enclosure is available. Each enclosure is ¼ DIN. The metal enclosure is rated NEMA 4X, while the plastic enclosure is NEMA 12 from the front and NEMA 1 from the rear.
The 873RS offers ranges of 0 to 2, 0 to 5, 0 to 10, 0 to 15 and 0 to 20 Mohm•cm.
When operating in dual sensor mode, the analyzer can either report two measurements independently or can be configured to compare the two sensors and report in units of % rejection or ratio.
873RS analyzers are compatible with 871CC series sensors. The 871CC sensor must have a cell factor of 0.1 cm-1 to operate with the 873RS analyzer.
