Description

THE'data recorder de water level HOBO U20-001-04 is a device in stainless steel designed for measure with accuracy on level and temperature water to a depth of 4 meters, adapted to variety of environments, including shallow wellsstreamslakes and freshwater wetlands.
With its narrow range, this recorder offers the better accuracy in shallow waters.
This is it recorder offers an excellent price quality ratio and one easy deployment for it does not require ventilation tubes neither desiccants bulky maintenance, making it an ideal choice for a ongoing monitoring.
THE'recorder is compatible with the software HOBOware Pro for a precise conversion data and several depth ranges to adapt to various applications.
In addition, it is designed with a protection against lightning, a design without ventilation tube for a easy deployment and reliable, and it is delivered with a calibration certificate traceable NIST in 3 points to ensure accuracy of measurements.

Technical specifications:

- Lightning protection: no long signal cables and electronic components are protected in a metal housing
- 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
- Available in stainless steel and titanium versions
- Durable ceramic pressure sensor
- NIST traceable calibration certificate in 3 points included

Features of the pressure and water level sensor:

- Operating range: 0 to 145 kPa (0 to 21 psia), approximately 0 to 4 m (0 to 13 ft) water depth at sea level, or 0 to 7 m (0 to 23 ft) water at 3,000 m (10 000 ft) altitude
- factory calibrated range: 69 to 145 kPa (10 to 21 psia), 0° to 40°C (32° to 104°F)
- Breaking pressure: 310 kPa (45 psia) or 18 m (60 ft) deep
- Water level accuracy*:
Typical error: ±0.075% FS, 0.3 cm (0.01 feet) water
Maximum error: ±0.15% FS, 0.6 cm (0.02 feet) of water
- Gross pressure accuracy**: ±0.3% FS, maximum error of 0.62 kPa (0.09 psi)
- Resolution: - Pressure response time (90%)*** :

* Water level accuracy: with precise measurement of the reference water level, known water density, accurate barometric compensation assistant data and stable temperature environment.
** Gross pressure accuracy: absolute accuracy of the pressure sensor includes all errors induced by sensor drift, temperature and hysteresis.
*** Temperature changes: Wait 10 minutes in the water to get a complete compensation of the pressure sensor temperature. The maximum error due to rapid thermal changes is about 0.5%.
