This 7-in-1 water quality meter measures pH, ORP, EC, TDS, salinity, specific gravity, and temperature in one portable device. Ideal for aquariums, pools, and drinking water monitoring.
The pen features a built-in high-sensitivity glass electrode with anti-rust platinum components for accurate readings. An IP67 waterproof rating and dust-proof splash-proof design make it suitable for wet environments. The LCD backlit screen ensures readings are clear and easy to view in any light.
Measuring range includes pH 0.01–14.00, EC 0–19,994 mS/cm, TDS 0–20,000 ppm, salinity 0.01–25.00%, ORP ±999 mV, specific gravity 1.000–1.222, and temperature 0–60°C. Accuracy specifications vary by mode: ±0.05 pH, ±2% FS for EC and TDS, and ±0.5°C for temperature.
The device is lightweight at 150 grams and measures 185 x 37 x 24 mm. It operates on three 1.5 V button cell batteries (not included). The plastic construction keeps the overall weight minimal whilst providing durability.
Multi-function mode switching lets you toggle between measurements quickly. This makes it efficient for regular water quality checks in aquariums, pools, or hydroponics systems.
Check the battery compartment and insert three 1.5 V button cells to get started.
