The square PC101 dual water quality tester precisely measures residual chlorine and pH levels for swimming pools, spas and hot tubs, replacing error-prone test strips for reliable daily water maintenance. Its compact square ABS casing boasts anti-corrosion and drop-resistant performance, easy to grip and store without taking much space.
Covering a chlorine range of 0–3ppm and pH 5.5–9.0, it provides accurate real-time readings within seconds once the probe immerses in water. Color-marked dial zones clearly mark balanced, low and excessive values to help users adjust water chemicals timely and prevent skin irritation.
No complicated reagent or frequent calibration required; it runs on common AAA batteries with low power drain for long service life. The integrated probe storage slot protects electrodes during transport, ideal for residential pool owners and commercial aquatics staff. This all-in-one portable monitor simplifies water chemistry balancing, an essential handy tool to keep pool water clean, safe and comfortable all year round.
