Características Destacadas
Proteção contra raios - sem cabos de conexão longos e eletrônica blindada em gabinete de aço inoxidável
O software HOBOware Pro oferece fácil conversão para leitura precisa do nível da água, totalmente compensada por pressão barométrica, temperatura e densidade da água (use dados de pressão barométrica da estação meteorológica próxima).
A amostragem de taxa múltipla permite uma amostragem mais rápida em momentos críticos, como quando o bombeamento começa ou pára.
Disponível em quatro faixas de profundidade
Ideal para utilização em poços, riachos, lagos, zonas húmidas e zonas de maré
Design de tubo sem ventilação para uma implantação fácil e confiável
Sensor de pressão de cerâmica durável
O kit KIT-D-U20-02 suporta as seguintes medições: Pressão absoluta, pressão barométrica, temperatura e nível de água
Pressure Sensor
Operation range: 0 to 400 kPa (0 to 58 psia); approximately 0 to 30.6 m (0 to 100 ft) of water depth at sea level, or 0 to 33.6 m (0 to 111 ft) of water at 3,000 m (10,000 ft) of altitude
Factory calibrated range: 69 to 400 kPa (10 to 58 psia), 0° to 40°C (32° to 104°F)
Burst pressure: 500 kPa (72.5 psia) or 40.8 m (134 ft) depth
Water level accuracy*: Typical error - 0.05% FS, 1.5 cm (0.05 ft) water
Maximum error: - 0.1% FS, 3 cm (0.1 ft) water
Raw pressure accuracy**: 0.3% FS, 1.20 kPa (0.17 psi) maximum error
Resolution: < 0.04 kPa (0.006 psi), 0.41 cm (0.013 ft) water
Pressure response time 90%: < 1 second
Thermal response time (90%)†: Approximately 10 minutes in water to achieve full temperature compensation of the pressure sensor
* With accurate reference water level measurement and Barometric Compensation Assistant data
** Absolute pressure sensor accuracy includes all pressure drift, temperature, and hysteresis-induced errors
† Maximum error due to rapid thermal changes is approximately 0.5%.
Temperature Sensor
Operation range: -20° to 50°C (-4° to 122°F)
Accuracy: 0.37°C at 20°C (0.67°F at 68°F)
Resolution: 0.1°C at 20°C (0.18°F at 68°F) (10-bit)
Response time (90%): 3.5 minutes in water (typical)
Stability (drift): 0.1°C (0.18°F) per year
Logger
Real-time clock: ± 1 minute per month 0° to 50°C (32° to 122°F)
Battery: 2/3 AA, 3.6 Volt Lithium, factory-replaceable
Battery life (typical use): 5 years with 1 minute or greater logging interval
