5-in-1 Aquarium Water Tester: pH value, TDS, EC value and salinity – precise and reliable for aquaculture and hydroponics

Extremely practical 5-in-1 function: This digital EC/PPM meter precisely measures pH, TDS (Total Dissolved Solids), electrical conductivity (EC), salinity, and temperature – ideal for saltwater pools, hot tubs, aquariums, drinking water, hydroponics, and koi ponds. Reliable and immediate results right on site. High precision and French ergonomics: This combination pH/EC/TDS/temperature meter is designed to meet the expectations of demanding users. It offers professional accuracy (±0.05 pH / ±2% FS) and an intuitive user interface, perfectly suited for individuals and professionals who care about water quality. Simplified one-click mode switching: Seamlessly switch between "Pool," "Hot Tub," and "Seawater" modes with predefined salinity ranges according to French standards: 2,700–3,400 ppm for pools, 2,000–3,000 ppm for hot tubs – for optimal chlorine generator operation. Automatic Temperature Compensation (ATC): 3-point calibration (pH 4.00 / 6.86 / 9.18) + automatic temperature compensation from 0 to 60 °C (32–140 °F) for stable measurements under all operating conditions. Easy-to-read, backlit LCD display, even in direct sunlight or dark indoor environments. Comprehensive measuring range and high resolution: pH (0.00–14.00, resolution 0.01), TDS (0–10,000 ppm, resolution 1 ppm), electrical conductivity (0–10,000 µS/cm, resolution 1 µS/cm), temperature (0.0–60.0 °C, resolution 0.1 °C), salinity (general/seawater/food-grade mode). Key specifications: Robust ABS material, 18 cm length, 155 g weight, operates on 3 LR44 batteries (not included), operating temperature range: 0–60 °C, pH accuracy ±0.05, TDS/EC accuracy ±2% FS, temperature accuracy ±0.5 °C. Package contents: 1 x digital water quality meter, 1 x calibration kit (buffer solution not included), 1 x user manual (French). This product is sold by xiaosong on behalf of a third-party seller.
