Frequently Asked Questions

What does the Gold Tip ORP Probe do?
The ORP (Oxidation-Reduction Potential) probe measures the sanitising effectiveness of your pool water in real time. The Viron eQuilibrium uses this reading to automatically increase or decrease chlorine output, keeping your pool consistently sanitised without manual adjustment.

What is Pro Mode and AI Mode on the Viron eQuilibrium?
Pro Mode and AI Mode are advanced automated control modes on the Viron eQuilibrium that use both pH and ORP data to intelligently manage water chemistry. These modes are only available when both the Gold Tip ORP Probe and the pH Sensor Kit are installed.

Is this probe suitable for spas and indoor pools?
Yes. The Gold Tip ORP Probe is particularly well suited to spas, indoor pools, and high-use environments where consistent sanitiser levels are critical.

Is this a genuine Astral Pool part?
Yes. This is the genuine Astral Pool Viron eQuilibrium Gold Tip ORP Probe (part number 525146), not an aftermarket substitute.
