With options to measure at depth ranges of 13, 30, or 100 feet in a wide range of underwater environments, this rugged logger features 0.1% measurement accuracy, a durable polypropylene housing for use in both freshwater and saltwater, and a non-vented design for convenient and reliable deployment.\u003c\/p\u003e\n\u003cp\u003eThe MX20L comes with a magnetic activation fob that can \"wake up\" the logger to activate its Bluetooth communication for configuration and data download. The included fob comes with a lanyard to prevent losing or dropping the fob in the field. Additional activation fobs are available for purchase.\u003c\/p\u003e\n\u003cp\u003eThis logger records absolute pressure, which is later converted to water level readings by HOBOconnect software. To compensate for barometric pressure changes, you can use another HOBO MX20L Water Level logger as a barometric reference.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSelf-contained, non-vented design enables easy deployment\u003c\/li\u003e\n\u003cli\u003eIdeal for use in both freshwater and saltwater environments, including wells, streams, lakes, wetlands, and tidal areas\u003c\/li\u003e\n\u003cli\u003eDepth measurement options of up to 13, 30, or 100 feet depending on model\u003c\/li\u003e\n\u003cli\u003eDurable ceramic pressure sensor withstands freezing\u003c\/li\u003e\n\u003cli\u003eStreamlined data offload via Bluetooth to the free HOBOconnect app\u003c\/li\u003e\n\u003cli\u003eHOBOconnect app provides easy extraction and visualisation of water level data\u003c\/li\u003e\n\u003cli\u003eExtended battery life up to 10 years (power-saving mode requires magnetic fob to activate Bluetooth for data download).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eRequires a compatible mobile device or Windows computer and the HOBOconnect app (available from iTunes or Google Play).\u003c\/p\u003e\n\u003cp\u003eNote: A calibration certificate is not offered for this logger.
