  • Measure temperature in air, water, or soil with the 6.1m (20 ft)  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.

  • UA-002-08

    Optical Interface for data transfer

    This HOBO Pendant® data logger is a miniature, waterproof two-channel temperature and relative light level data logger. The 8K model comes at a great value and is suitable for indoor, outdoor, and underwater applications. This logger holds approximately 6.5K of 10-bit readings. Use a solar radiation shield for accurate temperature measurement in sunlight.See RS1 Solar Radiation Shield (assembly required) and M-RSA (pre-assembled) Solar Radiation Shield. Note that using a solar radition shield prevents the use of the light sensor. 

    • Low-cost temperature with alarm indication or light intensity
    • Waterproof housing for wet or underwater use
    • Data readout in less than 30 seconds via fast Optic USB interface
