Ondilo – Spa in line ORP Redox Sensor Kit for Hot Tubs and Pools

The Ondilo Spa in line ORP / Redox sensor kit is a replacement sensor for the Ondilo Spa in line connected water analyser, used to monitor hot tub and pool water. It measures ORP (Oxidation-Reduction Potential), a close proxy for the amount of free chlorine or bromine in the water. The kit includes a buffer solution and a calibration and sensor replacement guide.

What the ORP sensor does

This Redox sensor is the part of the Spa in line analyser that reads the ORP value of your water. ORP gives a good indication of how much free chlorine or bromine is active, so the sensor is key to keeping an eye on your water treatment from your hot tub or pool.

It is a spare part only: it is intended for the Ondilo Spa in line system and is not a standalone water tester.

What is included in the kit

• 1 ORP Redox sensor
• 1 ORP 470 mV buffer solution (20 ml)
• 1 calibration and sensor replacement guide

If you also need to replace the pH probe, the Ondilo Spa in line pH sensor kit is available separately. A Ondilo Spa in line sensor calibration kit is also listed as a separate product.

Fitting the replacement sensor

Attach the sensor to the slot marked “ORP” on the manifold, following the instructions in the installation guide. Then connect the plug to the control box.

Calibration and maintenance

After the first season, recalibrate the sensors each time you restart your pool or spa, or every 6 months if you do not winterise. You should also recalibrate if you notice a drift in the measurements.
