Description
Zodiac P19 probe holder R0824600
The Zodiac P19 probe holder R0824600 is the dedicated mounting body for Zodiac P19 pH and Redox (ORP) probes.
It is used in Zodiac automatic treatment systems to hold the sensor in a stable, repeatable position in the water
stream, ensuring precise and continuous measurement of pH or Redox in your pool.
Main features of the Zodiac P19 probe holder
- Original Zodiac probe holder designed specifically for P19 pH and ORP probes.
- Next generation design used on Zodiac POD style installations from 2019 onwards.
- High density injected thermoplastic body for durability in pool plant rooms.
- Provides a stable, correctly oriented seating for accurate water analysis.
Compatibility and typical applications
This probe holder is used in Zodiac automatic dosing and measurement systems where P19 probes are installed in a POD
or dedicated probe chamber. It is suitable for both pH and Redox sensors and replaces older probe holder versions.
- Valid for Zodiac P19 pH and P19 Redox (ORP) probes.
- Used in Zodiac POD installations and modern pH and chlorine controllers.
- Designed for equipment manufactured from 2019 onwards that specifies R0824600.
- Replaces earlier Zodiac probe holder reference W043730 on compatible systems.
Always check the technical documentation of your controller or POD kit. If the spare parts list identifies the probe
holder as R0824600 for the P19 sensor, this is the correct replacement part.
Role in automatic water treatment
Accurate automatic dosing depends not only on the quality of the probe, but also on how it is installed in the water
circuit. The Zodiac P19 probe holder R0824600 positions the sensor at the correct depth and angle, reducing the risk of
air pockets or dead zones that can distort readings.
- Keeps the probe immersed in a representative flow of water from the filtration circuit.
- Helps avoid turbulence, air bubbles and stagnant areas around the measuring tip.
- Supports precise dosing of pH correcting chemicals or control of chlorinator output.
- Improves the reliability and repeatability of automatic measurements over time.
Installation guidelines
The probe holder is normally installed on a POD or sampling line that takes a small, constant flow of water from the
filtration system. Correct mechanical installation is essential for good sensor performance.
- Install the holder according to the flow direction and orientation recommended for your POD or sampling kit.
- Ensure the probe seating and threads are clean and free of burrs before inserting the sensor.
- Insert the P19 probe carefully, tightening by hand until the sealing ring is correctly compressed.
- Avoid overtightening, which can deform the seal or the thermoplastic body.
- Route the probe cable so that it is not under tension and is protected from sharp edges or hot surfaces.
After installation, verify that there are no leaks around the probe holder and that the sensor reading stabilises
normally according to the controller instructions.
Maintenance and best practices
The probe holder itself has no moving parts, but its condition influences how easy it is to service the sensor and
how reliably the system measures water quality.
- Inspect the holder periodically for cracks, discolouration or mechanical damage.
- Check the sealing surfaces and replace the probe sealing ring if you notice seepage.
- Rinse the inside of the holder with clean water when you remove the probe for cleaning or calibration.
- Avoid using sharp tools inside the seating area that could scratch the plastic or O-ring groove.
With a sound Zodiac P19 probe holder R0824600 and a correctly maintained probe, automatic pH and Redox control systems
can deliver accurate readings and efficient chemical dosing over many seasons.
