The Level2000 is a rugged, submersible, temperature and water level data recorder, perfect for use in harsh, chemical or corrosive environments. It's stainless steel enclosure features a vented cable and endcap, allowing it to automatically compensate for atmospheric pressure fluctuations. The vented cable also allows for real-time level monitoring and easy download while the data recorder is deployed in the environment. The Level2000 is also equipped with an internal temperature sensor for recording temperature, as well as water level data. Data can be displayed in standard or metric units.
