Kit with water level recorder kit (4m) KIT-D-U20-04

The KIT-D-U20-04 is one complete kit which allows monitoring highly precise of the water level in miscellaneous aquatic environments, such as well streams lakes and freshwater wetlands, while ensuring great ease of use.

The kit includes:
- A HOBO data recorder U20-001-04 with a range of 4 meters for barometric pressure.
- A waterproof U-DTW-1 HOBO shuttle equipped with 5 interchangeable couplers.
- A U20-CASE-1 transport case.
- Software HOBOware Pro for data analysis.

This kit ensures a exceptional accuracy in the measurement of the water levels, thus eliminating the need for bulky ventilation tubes or dehydratants to be maintained.
THE'data recorder U20-001-04 measures also barometric pressure, which is essential to correct changes de atmospheric pressure when measuring water levels.
The watertight shuttle simplifies the connection and data recovery under water in a manner waterproof, while the transport case allows safe and convenient transport of equipment.
Software HOBOware Pro this includes facilitating the conversion of data into accurate water level measurements, taking into account barometric pressure, temperature and temperature water density.
THE'recorder is designed for resisting lightning and is housed in a stainless steel case for a sustainability increased.
It offers the possibility of multirate sampling, which allows for frequent recording data, including critical changes, such as start or l'stop of the pumping.
It is well suited for use in a variety of aquatic environments, including wells, streams, lakes, wetlands and wetlands tidal zones, and its design without ventilation tubes bulky facilitates its deployment and guarantees its reliability.
The recorders are equipped with pressio sensorsn in robust ceramic 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
