Data Logging Water Quality Testers with Long Battery Life – GAOTek

Description Overview These data logging water quality testers are built for accurate monitoring, reliable performance, and long-term operation in diverse environments. Offering precise measurements across a wide flow range, they are suitable for both residential and industrial applications. With built-in data storage, they can record daily consumption for one year and maintain historical data for up to 24 months. Even during power outages, flow data and time are retained, ensuring uninterrupted records. Powered by a high-capacity lithium battery, these testers provide 6–8 years of consistent service. Advanced features such as IP68 protection, multiple communication options, and temperature resistance enhance durability and efficiency.   Features Wide flow measurement range with high accuracy Daily and historical data storage capacity Long-lasting lithium battery power supply Power outage protection with automatic recovery IP67/68 waterproof and dustproof protection Multiple communication options (M-BUS, RS485, NB-IoT, LoRaWAN, Pulse) Supports both horizontal and vertical installation Durable service life of over 12 years Integrated temperature sensor for accurate monitoring Stable operation under varying environmental conditions   Technical Specifications Parameter Details Accuracy Class Class 2 (±5% in lower zone, ±2% in upper zone) Pressure Stage MAP16 Pressure Loss (MPa) △p 0.04 Water Temperature Range 5℃ – 105℃ Environmental Requirement -15℃ to 55℃, RH <90% Data Storage Capacity 1 year daily storage, 24 months history (customizable) Power Outage Protection Saves accumulated flow & time; auto recovery after power restoration Interface & Communication M-BUS, RS485, NB-IoT, LoRaWAN, Pulse Power Supply DC 3.6V Lithium Battery Protection Class IP67 / IP68 Installation Orientation Horizontal & Vertical (Class 2) Durability / Service Life ≥12 Years NTC Temperature Sensor Model: MF52a-103□3380; R25=10kΩ; B(25/50℃)=3380k Connection Type G 3/4” (DN15), G 1” (DN20), G 1 1/4” (DN25) Battery Type Lithium Battery (Model: ER18505H) Battery Rated Capacity 9000mAh Battery Rated Voltage 3.6V Max Continuous Operating Current 100mA Max Pulse Current 200mA Battery Reference Weight 53g Battery Max Dimensions 26.2 × 50 mm Battery Operating Temperature -55℃ to 85℃ Power Consumption 1 time/24h → 6–8 years battery lifespan
