7-in-1 Water Quality Tester pH/EC/TDS/H2 ORP/Salinity for Aquariums and Marine Farming

Precise measurement of dissolved hydrogen (H₂): This meter detects the concentration of molecular hydrogen in water with a highly precise measuring range of 0 to 2400 ppb (0.001 to 2400 ppm) and a resolution of 1 ppb – ideal for assessing the effectiveness of hydrogen-enriched water, which has a positive impact on well-being and health. Comprehensive water quality analysis with 7 functions: pH (0.00–14.00), TDS (0–10,000 ppm), electrical conductivity (EC) (0–10,000 µS/cm / up to 400.0 mS/cm), redox potential (±999 mV), salinity (0.01%–25.00%), hydrogen concentration (H₂), and temperature (0.0–60.0 °C). Easy-to-read, backlit display: Clear digital display with permanent backlighting and long battery life. Long battery life ensures comfortable reading even in low light, whether in the kitchen, laboratory, or outdoors. Robust and waterproof (IP67): Shockproof ABS housing with full waterproofing (IP67 rating), ideal for demanding everyday use, even in humid environments or on the go. Long battery life and ergonomic design: Operates on 4 standard batteries (not included); compact design (180 mm) and lightweight (185 g) for comfortable and precise use anytime. Package contents: 1 x 7-in-1 multi-function water tester, 1 x user manual in French (other languages depending on availability). This product is sold by xiaosong on behalf of a third-party seller.
