With integrated Bluetooth technology, it provides quick and seamless wireless data offload, eliminating the need for cables or base stations and making fieldwork more efficient.<\/p>\n<p>Capable of measuring at depths of 4, 9, or 30 meters, the MX20L is designed for diverse applications in both freshwater and saltwater environments, including groundwater wells, streams, lakes, wetlands, and tidal areas. Its durable polypropylene housing and non-vented design ensure reliable performance even in harsh and long-term deployments. With an impressive 0.1% measurement accuracy, you can trust the MX20L for high-quality data collection.<\/p>\n<p>Using the free HOBOconnect app on a mobile device or Windows computer, the logger allows for easy setup, configuration, and data download. To further streamline deployment, it includes a magnetic activation fob, allowing you to effortlessly &#8220;wake up&#8221; the device to enable Bluetooth communication or download data.<\/p>\n<p>Whether you&#8217;re tracking changes in aquatic ecosystems, monitoring storm drains, or planning urban water resource management, the HOBO MX20L addresses challenges like data inaccuracy and difficult deployments, providing a reliable, field-ready solution. It\u2019s the perfect partner to empower your efforts in environmental monitoring and drive better decision-making for sustainable resource management.<\/p>\n<h3>Barometric Pressure Compensation<\/h3>\n<p>The MX20L records absolute pressure and converts it to water level via HOBOconnect. For accurate water level data, pair it with an additional <strong>MX20L-04<\/strong> logger for barometric pressure compensation. One baro logger covers multiple MX20L sensors in the same location; deploy additional loggers if sensors are spread across different sites or elevations.<\/p>\n<p><strong>Included Items:<\/strong><br \/>\n1 x MX20L Blue tooth Data Logger<br \/>\n1 x Magnetic Fob<br \/>\n1 x Lanyard<br \/>\n1 x Quick Start Guide<\/p>\n<h3>Discover Smarter Water Level Monitoring\u2014Get Started with the MX20L Today!<\/h3>\n<h3>Features<\/h3>\n<ul style=\"list-style-type: disc;\">\n<li>Equipped with a self-contained, non-vented design for seamless and straightforward deployment.<\/li>\n<li>Designed for versatility, suitable for both freshwater and saltwater environments, including wells, streams, lakes, wetlands, and tidal zones.<\/li>\n<li>Offers flexible depth measurement capabilities, available in models supporting depths of 4, 9, or 30 meters.<\/li>\n<li>Built with a robust ceramic pressure sensor capable of withstanding freezing conditions.<\/li>\n<li>Enables efficient data transfer through Bluetooth connectivity to the free HOBOconnect app.<\/li>\n<li>The HOBOconnect app ensures effortless extraction and clear visualisation of water level data.<\/li>\n<li>Features an extended battery life of up to 10 years, with power-saving mode activated via a magnetic fob for Bluetooth data downloads.<\/li>\n<\/ul>\n<p>The MX20L is a scalable solution that simplifies workflows and data collection from large numbers of wells for hydrologists, field technicians, mitigation specialists, and others, these loggers can offload data to <a href=\"https:\/\/www.onetemp.com.au\/nz\/product\/li-cor-cloud-iot-platform\/\">LI-COR Cloud\u00ae software<\/a> with an accompanying <a href=\"https:\/\/www.onetemp.com.au\/nz\/product\/li-cor-cloud-iot-platform\/\">MX Data Plan<\/a>, which gives users access to a range of time-saving tools.<\/p>\n<p><strong>Note:<\/strong> A calibration certificate is not offered for this logger.
