Kit kit with water level recorder (9m) KIT-D-U20-01

The briefcase with recorder kit de water level (up to 9m) KIT-D-U20-01 is a complete kit combining measurements of water level de high precision with convenience ready for use, this kit economic understands everything necessary to start record immediately.
It is ideal to monitor water levels and temperatures in well streams lakes and freshwater wetlands, and the barometric pressure.

This kit includes:

- HOBO data recorder U20-001-01 (range 9m)
- HOBO data recorder U20-001-04 (span 4m) for barometric pressure
- Waterproof U-DTW-1 HOBO shuttle with 5 interchangeable couplers
- U20-CASE-1 transport case
- Software HOBOware Pro

Like the others recorders de water level of the mark HOBO, the version of 9 m offers exceptional value and ease of use, without bulky ventilation tubes or dehydratants to maintain, it has a high precision to the extent water levels.
In addition to the water level recorders, the kit includes a HOBO data recorder for the barometric pressure which measures the atmospheric pressure, which is essential to compensate pressure variations barometric measurement of water levels.
The kit also comes with a watertight shuttle U-DTW-1 HOBO equipped with 5 interchangeable couplers, this shuttle allows connect and recover data from underwater recorders in a practical manner; and waterproof.
One transport case U20-CASE-1 is included for transport secure and equipment practice.
Software HOBOware Pro is provided for'data analysis, it allows easy conversion of data to precise reading water level, taking into account barometric pressure, temperature and water density.
The recorders are designed with a protection against lightning, and their electronics are housed in a housing en stainless steel for a sustainability increased.
The equipment offers the possibility of multirate sampling, which allows for more frequent recording of data, in particular when critical changes, like start or'stop pumping.
These recorders are suitable for use in a variety of'aquatic environments, including wells, streams, lakes, wetlands and tidal zones.
Unlike some other recorders, these water level recorders do not need bulky ventilation tubes, which makes it easier for them to use the water level recorders deployment and their reliability.
The recorders are equipped with pressure sensors ceramics robust for accurate and sustainable measurement of water levels.

Technical specifications:

- Protection against lightning, no long signal wires and electronics is protected in a stainless steel case
- The HOBOware Pro software 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
