HOBO Fresh Water Conductivity Data Logger

Acqua dolce

Misura e registra la conducibilità e la temperatura di corsi d'acqua, laghi e altre fonti d'acqua dolce; è consigliato per il monitoraggio delle falde acquifere per l'intrusione di acqua salata e per il deflusso stradale e agricolo.

Informazioni importanti

Richiede HOBOware Pro software e un U-DTW-1 Navetta impermeabile o il Base-U-4 Stazione base USB ottica per la configurazione e il trasferimento dei dati. Vedere gli articoli compatibili di seguito.

Overview

A high-accuracy, cost-effective data logger that measures and records conductivity and temperature in streams, lakes, and other freshwater sources. Recommended for monitoring aquifers for saltwater intrusion and road and agricultural runoff, this logger's open access to its sensor simplifies cleaning and maintenance, and its non-contact sensor minimizes measurement errors related to drift. Also features software-based drift compensation.

The titanium pentoxide coating on the non-contact sensor prevents it from coming into contact with the water, thereby preventing tarnishing or corrosion associated with traditional electrode sensors. This sensor coating is also inert, so fouling can be easily wiped off the sensor.

Features

Titanium pentoixed coated non-contact sensor rovides long life and less measurement drift
Provides easy access to sensor for cleaning and shedding air bubbles
HOBOware Pro software enables start/end-point calibration to compensate for any fouling and provides easy conversion to specific conductance and salinity
USB optical interface provides high-speed, reliable data offload in wet environments
Compatible with the HOBO Waterproof Shuttle for easy and reliable data retrieval and transport
