The MX20L Water Level Logger brings you all the same great features as the U20L and more!
Integrating Bluetooth for fast and reliable data download, the MX20L logger eliminates the need to plug your logger into a base station or shuttle to offload data in the field, ensuring continuous water level and temperature monitoring. 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.
The 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. You can purchase additional activation fobs HERE.
This logger records absolute pressure, which is later converted to water level readings by our HOBOconnect software. To compensate for barometric pressure changes, you can use another HOBO MX20L Water Level logger as a barometric reference. See our FAQ section for more information.
Note: A calibration certificate is not offered for this logger. If you require a NIST-traceable calibration certificate, please see theU20-001-01(freshwater)or U20-001-01-Ti(saltwater).
* Water Level Accuracy: With accurate reference water level measurement, known water density, accurate barometric compensation data, and a stable temperature environment.
** Raw Pressure Accuracy: Absolute pressure sensor accuracy includes all sensor drift, temperature, and hysteresis-induced errors.
*** Changes in Temperature: Allow 20 minutes in water to achieve full temperature compensation of the pressure sensor. Maximum error due to rapid thermal changes is approximately 0.5%.
