5.0-50℃ Wide Temperature Working Range to Avoid Data Interruption Caused by Temperature Changes
The device maintains stable operation under 0 to 50 centigrade all weather conditions, resisting summer high temperature exposure and low temperature cold weather. It will not shut down frequently due to temperature fluctuation in outdoor monitoring, ensuring continuous complete water quality records to avoid failing environmental inspection due to missing data.

6.Modular Split Structure to Cut Later Operation and Maintenance Investment
Adopts split modular structure of buoy collector and independent probes, the collector service life reaches more than 2 years while each probe can be replaced separately. When one sensor malfunctions, only the damaged probe needs replacement instead of the whole buoy, greatly reducing your later maintenance and replacement expenditure.
