Temperature Data Loggers
Onset offers a wide selection of temperature data loggers for reliable, accurate data collection under tough environmental conditions. There are temperature data loggers appropriate for indoor, outdoor and underwater applications, in a variety of sizes, from handheld units to tower weather stations.
Temperature data collection requires a sensor and a data logger; some Onset data loggers contain internal sensors, while others require input from an external temperature sensor that plugs into the logger unit. There are also several options for accessing the data, ranging from manual download directly to a laptop computer to remote communications via cellular or Wi-Fi networks.
Onset's temperature data loggers are used in a wide variety of applications, including energy performance monitoring, indoor air quality, green building and renewable energy systems monitoring, and climate research.
