Compact pH CL2 Pool Tester

Dedicated analog tester for monitoring two essential water quality indicators: pH (7.2–7.8) and free chlorine (1.2–1.7 ppm) in residential pools and spas. Small, lightweight body with hanging hole for wall-mounting or hook storage. High-contrast analog dial allows instant visual assessment without magnification or lighting aids. Manufactured from dense, abrasion-resistant plastic to endure regular handling and humid environments. Operates using one AA 1.5V alkaline battery (not supplied). Chlorine measurement must be calibrated once before first use using a liquid test kit baseline; pH remains stable thereafter. Probe must be inserted only to the black band, gently stirred in water, then rinsed and dried. Always store with switch in 'PH' position, in darkness and low humidity.
