HOBO UA Logger for temperature in Water/Ice with PVC Case prepared for extreme conditions.

The miniature HOBO Pendant UA is a waterproof, one-channel temperature data logger.
This 8K or 64K model is value-priced for deployment in indoor, outdoor, and underwater applications measuring relative light levels and ambient temperatures.
Data logger alarm LEDs flash if temperatures have exceeded user-set levels and delay options, and provide visible verification that temperatures have been within the desired range throughout deployment.
The 8K model UA-001-08 stores approximately 6.5K of 10-bit temperature readings.
The 64K model UA-001-64 stores approximately 52K of 10-bit temperature readings.


  • Low-cost temperature logger with alarm status indication. 
  • Waterproof housing for wet or underwater use.
  • Data readout in less than 30 seconds via fast optic USB interface.
