Data Loggers

The HOBO Pro v2 Temperature/External Temperature data logger is a weatherproof data logger with an external soil/water temperature sensor on a 6-foot cable useful for situations where just one temperature probe is required. An internal temperature sensor is also included.

Features:

Weatherproof housing for use in outdoor or condensing environments
High accuracy
Replaceable Relative Humidity sensor provides fast response and superior recovery from condensing conditions
Small-diameter external sensor versions for measurements in tight spaces
Optic USB interface for fast and reliable download
 
Environment: Outdoor
Measurement: Temperature
