It is a more cost-effective water level logger (water level gauge) than the M193U-WL201P series.
This is a low-cost research-grade water level data logger for continuously monitoring water levels and temperatures in various underwater environments, with a sensor, memory, and battery in a single structure.

Applications/Examples of results
● It can be easily deployed due to its self-contained non-ventilated design. ● Ideal for use in both freshwater and saltwater environments such as wells, streams, lakes, wetlands, and tidal zones. ● Supports depths of up to 4m, 9m, and 30m depending on the model. ● Durable ceramic pressure sensors are resistant to freezing. ● The paid software fully compensates for atmospheric pressure, temperature, and water density, allowing for easy conversion to accurate water level readings.
