The 3500 is a fully programmable controller suitable for precision control of temperature, dew-point, carbon potential and oxygen in atmosphere heat treatment applications.

It is capable of being used solely to control the carbon potential, oxygen in a furnace or dew-point. Also functioning as an integrated furnace controller where any of these variables are controlled in conjunction with temperature. Additional features provide combined logic and math functions.

At the heart of the controller is a specially designed function block capable of accepting most zirconia probes. Standard features include an automatic probe cleaning routine, a shooting alarm and diagnostics indicating that the probe is about to fail and should be replaced.
For standard solutions controllers can be configured with features and user screens.

User customization can be achieved by reconfiguring the unit either via the front panel or the comprehensive PC based Eurotherm iTools.
A complete data sheet on the dual loop version of the 3500 is available HA029045.
