Measure temperature in air, water, or soil with the 6.1m (20') TMC20-HD temperature sensor. This product is designed to be used with HOBO U-Series, UX120-006M external-channel data loggers or ZW series wireless datanodes. This sensor records temperatures between -40° and 50°C (-40° to 122°F) in water or soil, and between -40° and 100°C (-40° to 212°F) in air. This product provides a response time of minutes typical to 90% in air moving 1 m/sec (2.2 mph); and 1 minute typical to 90% response time in stirred water. Please note, accuracy and resolution depend on data logger.

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.
