RDO® Blue Optical Dissolved Oxygen Sensor RDO BLUE IS AN OPTICAL DISSOLVED OXYGEN SENSOR DESIGNED FOR DEMANDING ENVIRONMENTS WHERE YOU NEED RELIABLE DO MEASUREMENTS AND WIDESPREAD COVERAGE TO OPTIMIZE YOUR SITE. RDO Blue is suitable for freshwater or saltwater applications and is ready for connection with transmitters, controllers, dataloggers, or telemetry. RDO Blue can also be used in a hand-held configuration for spot-checks and site assessments. DO MORE FOR LESS RDO Blue sensors are low power, low maintenance, and low cost so you can monitor wherever you need to. Instead of spot-checking sites with a shared probe or installing one sensor per site, pond, or tank, you can affordably install RDO Blue in multiple locations for comprehensive insight about DO conditions that affect your aquatic organisms. For aquaculture applications, this will help you optimize aeration and feeding to lower operational costs while maintaining the health of your stock. For environmental applications, access to data from more locations allows you to fully characterize your site, identify problem areas, and gain valuable insight to guide decisions. ENHANCED RELIABILITY The redesigned RDO Blue is made from Ryton, a high-performance material used to replace metal parts in automotive and heavy industrial applications. It’s lightweight, strong, and resistant to chemicals, corrosion, abrasion, UV exposure, and high heat. Anti-rotational teeth lock the housing and sensor tip together to provide a strong, reliable connection between parts. Internal potting around the cable connection ensures the electronics are protected from humidity even in tough conditions. SHARED ECOSYSTEM With the Twist-Lock option, RDO Blue plugs into the In-Situ ecosystem and allows you to collect readings, calibrate, and manage the instrument with a Wireless TROLL Com and VuSituTM. This mobile solution keeps your data organized and geographically accurate by enabling data collection at distinct sites with GPS tags. With your logged data, you can conveniently email, share or export log files right from your mobile device so that your information is accessible when you need it. You can also connect RDO Blue to VuLinkTM to create a simple and complete solution with power, logging, and telemetry for your critical DO data. With HydroVuTM for advanced data visualization and site information, you get a comprehensive overview of your monitoring sites and can set up alarms for notification of critical site conditions.
