Air/Water/Soil Temp Sensor (50' cable) - TMC50-HD

A temperature sensor for use with HOBO U-Series 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 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 15.2m (50 ft) cable.
