Pool spare parts, dosing controllers and water analysis equipment

Here you will find the complete catalogue: everything from a single magnetic stir bar or a length of peristaltic tubing through to fully assembled pH, ORP and free chlorine controllers that dose acid and disinfectant automatically. The range is built around the parts that keep an existing installation running, so most items are identified by a manufacturer code — HI70483, HI704871, BL121-10 — rather than by a generic description. Ordering by that code is always the safest route.

What the range covers

The catalogue is organised around the water treatment chain: measure, control, dose, filter and circulate. Within that, the most frequently ordered groups are:

• Controllers and analysers — panel and in-line instruments that read pH, ORP (redox) and temperature, and continuous analysers such as the PCA series that measure free chlorine alongside pH.
• Dosing hardware — integrated peristaltic pumps, solenoid valves, injection fittings and flow cells, plus the mounting kits that hold a probe in the pipe run.
• Electrodes and probes — pH, ORP and amplified ORP/temperature sensors, which are consumable items with a finite service life.
• Reagents and standards — liquid reagents for continuous analysers, including free chlorine reagent for the 0–5 mg/L range, and the buffer and calibration solutions used to keep readings honest.
• Wear parts and service kits — tubing sets, measuring cells, stir bars, O-rings, filters and seals.

How the Hanna Instruments pool controllers are identified

The BL Pool Line models follow a logical pattern that makes selection much easier once it is understood. The base number describes the measurement and the dosing method: BL100 is a pH controller with a built-in peristaltic pump, BL101 is the equivalent for ORP, while BL121 and BL122 read pH, ORP and temperature together. BL131 and BL132 are intended for installations that already have external dosing pumps and only need the control signal. The suffix then describes the mounting and what is in the box — a -00 version supplied with a probe, a -10 in-line version with a collar or tee for fitting directly into the pipework, and a -20 version supplied as a panel with a flow cell for wall mounting. Models in the BL122 and BL132 families add connectivity, with Ethernet and Hanna Cloud functions for remote monitoring.

For continuous free chlorine monitoring, the PCA series analysers such as the PCA320-2 combine a chlorine measurement with pH and are supplied with reagent and electrode. These instruments draw a small sample continuously, so their consumables are shared across the series.

Choosing the right spare part

Analysers and dosing systems fail at predictable points, almost always in the fluid path. Peristaltic tubing hardens and loses output long before it bursts; measuring cells cloud and stain; stir bars wear or are lost during cleaning; solenoid valve coils and diaphragms age. Before ordering, work through the following:

• Confirm the instrument model from the label or the front panel, not from memory — PCA consumables differ from BL consumables.
• Check the version where one exists. The measuring cell for PCA series analysers, for example, is supplied as a v.2 part (HI704871), so the revision matters.
• Match the electrical rating on electromechanical items. A solenoid valve rated 24 VAC / 50 Hz (HI70489) must not be substituted with a different coil voltage.
• Count what you need. Tubing is offered both as a single complete kit (HI70483) and as a pack of three (HI70484), and stir bars come in pairs (HI70486) — useful if the analyser is on a service schedule.
• Measure seals and O-rings across the inside diameter and the cord thickness when the original part number is no longer legible.
• Check reagent ranges against the expected chlorine level; a 0–5 mg/L reagent suits normal pool disinfection but not high-concentration dosing.

The stock covers complete control and dosing systems as well as the small consumables that keep them calibrated and accurate, so a pool can be maintained from one source rather than through several suppliers. Keeping the reagents, tubing kits, cells and electrodes alongside the instruments themselves means a service visit does not have to end with a controller left offline.

Parts are listed with manufacturer codes wherever possible, which allows a part to be cross-checked against an exploded view or a service manual before it is ordered. If an item appears in several versions, the version is stated in the product name so the correct one can be chosen with confidence.
