The 873DPX analyzer is a dual sensor input pH, ORP or ion selective electrode (ISE) analyzer. The 873DPX is line-powered.
The 873DPX can be configured to operate in many different modes. For example, it can handle 2 pH sensors, 2 ORP sensors, one pH and one ORP, or one ISE and one pH. In the ISE mode, it can be configured to provide compensation for the pH of the solution as measured by the secondary (pH) sensor.
Each 873DPX analyzer provides two analog output signals (4-20 mA, 0-10 V, 0-20 mA), and two alarm relays.
Mounting is via a metal, field-mount enclosure. The enclosure is ¼ DIN and rated NEMA 4X.
A built-in preamplifier allows compatibility with unamplified pH or ORP sensors. However, Foxboro sensors with built-in preamps are also compatible.
