Quick and reliable water readings for pools and spas. The water quality digital monitor reads pH and chlorine levels fast and accurately, helping you keep pool and spa water safe, comfortable, and properly balanced without relying on color charts or test strips. precision and accuracy. pH readings have a resolution of 0.01 and an accuracy of ±0.05. The device covers the full pH range (0 to 14) and is factory calibrated for immediate use. Clear saferange guidance. Chlorine is measured with safe pool/spa targets at 1.2 to 1.7 ppm, while pH should be maintained in the safe range of 7.2 to 7.8. Portable and convenient design. Handheld pen type with a compact form factor that fits in a pocket or bag. Builtin automatic temperature compensation (ATC) means you can obtain accurate pH readings without separately testing the liquid temperature, across 0 °C to 80 °C (32 °F to 176 °F). Wide range of applications. Ideal for swimming pools, spas, tap water, home brewing, laboratory testing, aquarium maintenance, and other water quality checks. This electric tester provides simultaneous pH and chlorine readings to support routine monitoring. Easy to use and lowmaintenance. Digital readout eliminates the need for color charts or test strips, delivering straightforward results with minimal setup. The meter is calibrated at the factory for readytouse reliability.
