Product Description
The 873RS-AIYFNZ-7 is a line-powered electrochemical analyzer from the Foxboro 873 series, engineered for precise resistivity monitoring in industrial aqueous solutions. It supports dual-sensor input, making it ideal for high-purity water applications, including demineralizer outputs and semiconductor wash-water quality control.
This transmitter features an intuitive human-machine interface with a rugged front panel, enabling direct calibration and configuration without external communicators. Its plastic NEMA 4X enclosure ensures durability in corrosive or wash-down environments, maintaining accurate measurements under demanding chemical processing conditions.

Technical FAQ
Can this model handle temperature-compensated measurements?
Yes. The analyzer automatically compensates for temperature variations using Pt100 or Pt1000 RTDs, which is essential because resistivity is highly temperature-dependent.
Is the enclosure resistant to chemical cleaning agents?
Yes. The NEMA 4X plastic enclosure is chemically resistant and suitable for frequent wash-downs in food, beverage, and chemical plant environments.
