Registrador de datos HOBO de Titanio para Temp/Nivel del Agua (0 - 9m)

Características destacadas

Protección contra rayos: no hay cables de señal largos y los componentes electrónicos están protegidos en una carcasa de titanio para su uso en agua salada.
El software HOBOware Pro proporciona una fácil conversión a una lectura precisa del nivel de agua, totalmente compensada por la temperatura de la presión barométrica y la densidad del agua.
Con el muestreo de velocidad múltiple se pueden realizar tomas de muestras más rápidas en momentos críticos, como cuando se inicia o se detiene el bombeo.
Disponible en 4 gamas de profundidad
Ideal para su uso en pozos, arroyos, lagos, humedales y zonas de mareas.
Diseño sin tubo de ventilación para un despliegue fácil y fiable
Disponible en versiones de acero inoxidable y titanio
Sensor de presión de cerámica robusto
Incluye certificado de calibración NIST de 3 puntos.

El registrador de datos U20-001-01-Ti soporta las siguientes mediciones: Presión absoluta, presión barométrica, temperatura y nivel de agua

• Water Level Accuracy: With accurate reference water level measurement, known water density, accurate Barometric Compensation Assistant data, and a stable temperature environment.

** Raw Pressure Accuracy: Absolute pressure sensor accuracy includes all sensor drift, temperature, and hysteresis-induced errors.

*** Changes in Temperature: Allow 10 minutes in water to achieve full temperature compensation of the pressure sensor. Maximum error due to rapid thermal changes is approximately 0.5%.
