These are diagnostic tools designed to assess the chemical balance of water in enclosed recreational water systems. These devices typically consist of small, plastic strips embedded with chemically reactive pads that change color when exposed to specific substances in the water. The resulting color variations are then compared to a reference chart to determine the levels of pH, alkalinity, sanitizers like chlorine or bromine, and other important water chemistry parameters.
Maintaining proper water chemistry within these systems is essential for bather safety and equipment longevity. Unbalanced water can lead to skin and eye irritation, ineffective sanitization allowing for the growth of harmful bacteria, and corrosion or scaling of the spa’s plumbing and surfaces. Regular utilization of these assessment tools provides a proactive approach to maintaining optimal water quality, minimizing health risks, and extending the lifespan of the spa system.
