How does Cobalt ML3 work?

  • Cobalt ML3 data loggers are fast and easy to install, generally with just single receiver for private networks. In addition to an internal temperature sensor, data loggers may be equipped with an external digital sensor.
  • Data is stored locally in data logger memory and on OCEACloud, which interacts with the responsive OCEAView web application, for remote viewing and management using a smartphone, tablet, or computer.
  • Data loggers send an alarm to the server if any excursion or other anomaly occurs, with alerts sent to users via e-mail, or by SMS/text message or voice message 24/7 by the optional OCEAlert platform.
