Portable pH conductivity meter for multifunctional water quality analysis, white – battery-free

✅ Precise and versatile measurement: Enables simultaneous measurement of electrical conductivity (EC), concentration factor (CF), and dissolved solids concentration (ppm) for a wide variety of crops – without recalibration, even at high conductivity levels. ✅ Fully automatic operation: Measurement starts automatically as soon as the probe is immersed in the nutrient solution. Results are instantly displayed on a bright, waterproof LED scale that is intuitive and easy to read, even in humid environments. ✅ Extremely flexible application: Ideal for hydroponics, aquariums, aquaculture ponds, swimming pools, farms, laboratories, and industrial water monitoring – one device for all your water quality needs. ✅ Ergonomic and portable design: Compact pen shape, lightweight (only 243 g), and small dimensions (415 × 23 mm) – perfect for quick checks in the field, greenhouse, or laboratory. ✅ Automatic temperature compensation: The measurement is automatically corrected to 25 °C, ensuring stable, reproducible, and reliable results regardless of ambient conditions (0–50 °C). Measuring range: 0.4–5.2 mS/cm (EC) / 4–52 CF / 280–3640 ppm (EC × 700) or 200–3000 ppm (EC × 500) – with multiple compatible ranges for maximum flexibility depending on the crop. Accuracy and resolution: Accuracy ±4%; resolution of 0.1 mS/cm (EC), 1 CF, 70 ppm (× 700), or 50 ppm (× 500). Power supply and battery life: Operates on 3 AA batteries (not included) – easy installation and quick battery replacement. Material and workmanship: Robust ABS housing, elegant white and gold design, splash-proof and shock-resistant. Package contents: 1 × water quality tester + 1 × multilingual instruction manual (including French). This product is sold by xiaosong on behalf of a third-party seller. It is compatible.
