A temperature sensor for use with HOBO external-channel data loggers, this model measures temperature in air, water, or soil.

Accuracy and resolution vary according with attached logger model. Measurement range is -40 to 50C (-40 to 122F) in water or soil, -40 to 100C (-40 to 212F) in air

Response time is minutes typical to 90% in air moving 1 m/sec (2.2 mph); response time in stirred water is 1 minute typical to 90%. This model sensor is attached to a 6.1m (20 ft) cable.
