FAQ

Can the SUP-pH8.5 measure both pH and ORP simultaneously?

No. The SUP-pH8.5 is a single-channel controller that can be configured for either pH or ORP measurement. It supports both analog and digital sensors, but only one measurement type can be monitored at a time. If simultaneous pH and ORP monitoring is required, two controllers or a multi-parameter analyzer should be used.

Does the controller support automatic temperature compensation?

Yes. It supports both automatic and manual temperature compensation using compatible temperature sensors to improve measurement accuracy.

Is the controller suitable for outdoor installation?

The enclosure provides IP65 protection. For outdoor use, it should be installed inside a suitable weatherproof control cabinet to ensure long-term reliability.

How many relay outputs are available?

The controller includes three programmable relay outputs that can be configured for alarms, cleaning functions, or process control.
