THE' data recorder de water level HOBO U20L-04 is a solution of measurement and ongoing monitoring low cost quality standards level and the water temperature in a wide range ofaquatic environments and until 4m depth.
It presents a accuracy of 0.1%, one polypropylene housing for use in freshwater and salt, and one design not ventilated for one practical deployment and hassle-free.
This data recorder requires either the U-DTW-1 waterproof shuttle or the optical USB base station Base-U-4 for configuration and unloading of data and software HOBOware Pro.
Technical specifications:
- Autonomous and unventilated design allows easy deployment
- Ideal for use in freshwater and salt water environments, including wells, streams, lakes, wetlands and tidal areas
- Depths up to 13, 30 or 100 feet depending on the model
- Durable ceramic pressure sensor resistant to frost
- Software HOBOware Pro allows easy conversion to accurate water level reading, fully compensated for barometric pressure, temperature and water density.
Note: A calibration certificate is not proposed for this recorder .
If you need a NIST traceable calibration certificate, please consult the U20-001-04 (fresh water) or U20-001-04-Ti (salt water).
