Kit with water level recorder kit (30m) KIT-D-U20-02

The KIT-D-U20-02 is one complete kit offering a monitoring of the water level de high precision and a great ease of use.
It is perfectly suitable for monitoring water levels temperatures and of barometric pressure in miscellaneous aquatic environments such as well streams lakes and freshwater wetlands.

The kit includes:
- a HOBO data recorder U20-001-02 (range 30m)
- a HOBO data recorder U20-001-04 (range of 4m) for barometric pressure
- a waterproof U-DTW-1 HOBO shuttle with 5 interchangeable couplers
- a transport case U20-CASE-1
- software HOBOware Pro for data analysis

This is kit offers high precision in the measurement of the water levels, eliminating the need for bulky ventilation tubes or desiccants to be maintained.
It also includes: data recorder for the barometric pressure, essential to compensate changes de atmospheric pressure when measuring water levels.
The watertight shuttle facilitates connection and recovery underwater data in a manner waterproof.
One transport case is included for transport secure and equipment practice.
Software HOBOware Pro allows easy conversion of data to precise readings water level taking into account barometric pressure, temperature and density water.
The recorders are designed for resisting lightning and are housed in a stainless steel case for a sustainability increased.
They offer the possibility of multirate sampling, which allows frequent recording data, particularly when critical changes such as start or'stop of the pumping.
These recorders are suitable for use in various aquatic environments, including wells, streams, lakes, wetlands and tidal areas, and their design without ventilation tubes bulky deployment and guarantees reliability.
The recorders are equipped with pressure sensors en ceramics robust for a precise measurement and sustainable water levels.

Technical specifications:

- Protection against lightning, no long signal wires and electronics is protected in a stainless steel case
- Software HOBOware Pro allows easy conversion to accurate water level reading, fully compensated for barometric pressure, temperature and water density.
- Multiple rate sampling allows faster sampling at critical times, such as when pumping starts or stops.
- Available in four deep beaches
- Ideal for use in wells, streams, lakes, wetlands and tidal areas
- Aeration tube-free design for easy and reliable deployment
- Durable ceramic pressure sensor
