Introduction
Product Definition
The A67 4-in-1 Water Quality Testing Pen is a portable water quality testing instrument that integrates TDS (Total Dissolved Solids), pH (acidity/alkalinity), EC (electrical conductivity), and temperature detection. The product features a pen-style integrated design with a built-in high-definition LCD display and multiple electrode sensors, enabling fast and intuitive reading of key water quality indicators. It is suitable for various scenarios such as household drinking water, aquarium keeping, aquaculture, horticulture, and water purification.
Product Introduction
The A67 4-in-1 Water Quality Testing Pen integrates four detection functions—TDS, pH, EC, and temperature—into a single pen-shaped device. Users can switch measurement modes via the buttons and read the measured values on the LCD display in real time. The product supports detection ranges of TDS 0~9999ppm, pH 0~14, EC 0~9999us/cm, and temperature 0~50°C, with an accuracy of ±10%. The device features IP67 waterproof capability, uses a 1.5V LR44 button cell battery with a battery life of approximately six months, and automatically powers off after 5 minutes of inactivity.
The product structure includes: battery compartment, high-definition LCD display, power button, mode/calibration button, hold/temperature button, maximum immersion line, electrode protective cap, EC/TDS electrode, external reference electrode, glass electrode, and temperature sensor.
