HI8720 ORP panel mounted controller is ideal for process control monitoring in a wide range of industrial applications, allowing for the selection of a set point for oxidizing or reducing dosage.
Built-in autodiagnostic functions to enable the user to check and troubleshoot any malfunctions. The functions are made via front panel keys to isolate the cause of malfunction.
These contacts (maximum 2A, 220 V) are for reduction and oxidation reactions when the pH controller is used with an ORP Controller. In these applications, the consent contacts of both meters are connected together to link the ORP and pH controllers so that ORP dosage will occur only if the actual pH value is correct, to avoid overdosage of oxidants or reductants that can lead to pollution.
If the measured ORP is not within the tolerance of the set value, the alarm contact is closed. This can occur if there is insufficient dosage or if there is overdosage.
You can choose the output configuration for connecting a recorder or a PLC, between 0-20 or 4-20 mA
When used in conjunction with the HI 8710 pH controller, the ODCD (ORP dosing consent device) function (featured by the HI 8710) will ensure that the ORP dosage will start only when the pH level is correct.
A removable, transparent splash-proof cover protects the front panel.
