• The Right Sensors

  The Hach si792 P pH/ORP 2-wire Transmitter is designed for use with the following Hach GLI world-class sensors: (1) pHD and LCP differential pH and ORP sensors and (2) Conventional combination technology pH and ORP sensors

  Multiple Communication Protocols

  The si792 P transmitter is available with digital communication functionality to connect easily to a communication network of choice, including HART®, PROFIBUS PA, or Foundation® Fieldbus.

  Area Rate to Suit Your Needs

  The si792 P transmitter is available as Class I, Division 2 (C I, D 2) with HART communications only or as intrinsically safe, Class I, Division 1 (C I, D 1) with HART, PROFIBUS PA, or Foundation Fieldbus. FM, CSA, and ATEX certified.

  Easy-to-use Intuitive Interface

  A logical menu structure, combined with icon based messages allows for intuitive operation. The large, clear liquid crystal display shows the measurement value, process temperature, and sensor and transmitter status. A transmitter or sensor error is indicated by a bright red LED and a message is displayed.

  Sensor Diagnostics

  The si792 P transmitter performs self-diagnostics and sensor monitoring such as asymmetry potential, slope, response time, cable integrity, glass, and reference impedance.
