A temperature sensor for use with HOBO U-Series, UX120-006M external-channel data loggers, or ZW series wireless datanodes. This model measures temperature in air, water, or soil. Accuracy and resolution vary according with attached data logger model. Measurement range is -40° to 50°C (-40° to 122°F) in water or soil, -40° to 100°C (-40° to 212°F) 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 0.3m (1') cable.

Can be plugged directly into the external input jacks of U12, UX120, or ZW Family loggers to expand the range of measurement options and applications.
