HR8800S Self-contained Intelligent Water Level and Temperature Recorder

1. Overview

The HR8800S is a self-contained battery-powered liquid level monitoring device designed for long-term recording of water depth (pressure) and temperature. It features a stainless steel or titanium alloy structure. The water level logger includes water level and temperature sensors, built-in high-capacity flash memory, and a high-capacity long-life lithium battery. All functions are integrated within the instrument's 26mm diameter metal housing, making it suitable for measuring water level and temperature in surface water, groundwater, and marine environments.
