Part of Balboa's smart spa ecosystem, the Balboa Purezone Dock system is an inline digital water analyser that automatically measures and logs your hot tub's water quality. Installed inside the spa's filter housing, it accurately monitors pH, free chlorine, total alkalinity, and temperature using an onboard optical sensor. Each reading is sent to the Balboa Purezone mobile app, where you can review trends, receive alerts and water treatment recommendations, and export data as needed.
Key Features
Inline water testing system with built-in optical sensor
Measures parts per million (PPM) for audit-ready accuracy
Monitors pH, free chlorine, bromine, and alkalinity
Sends results to the mobile app for alerts, logging, and export
Adjustable test frequency with self-calibrating operations
Exportable logs suitable for health and safety audits, service records, and trend tracking
No test strips, no plumbing modifications, no manual cleaning
The unit calibrates itself before every test and uses replaceable cassettes capable of 30 readings each. One cassette is included with the unit. By default, it tests every two days though this can be adjusted to suit your cleaning schedule requirements. The app tracks remaining tests per cassette, so you're never caught off guard.
Designed to sit discreetly in the spa's filter housing, the Dock version of the Purezone system is especially suited to commercial and guest-facing setups. It provides a tamper-resistant, out-of-sight solution with no interference to spa use.
