An instrument designed to analyze the chemical composition of water within a hot tub environment. This typically includes reagents, test strips, or digital meters to measure pH levels, alkalinity, sanitizer concentration (chlorine or bromine), and calcium hardness. The purpose is to provide data about the water’s condition.
Regular employment of such analytical tools is crucial for maintaining a safe and healthy bathing environment. Balanced water chemistry prevents skin and eye irritation, inhibits bacterial growth, and protects the spa’s equipment from corrosion or scaling. Historically, visual inspection and subjective assessment were common, but modern kits offer more precise and reliable data.
