HOBO® UA-001-64 Data Logger
64K Pendant Temperature/Alarm (Waterproof)
A miniature, waterproof one-channel temperature data logger, this
model is value-priced for short-term shipping applications or longterm deployment. 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. This 64K model stores approximately
52K of 10-bit temperature readings. For accurate temperature
measurement in sunlight a solar radiation shield is required (RS1
Solar Radiation Shield, assembly required; M-RSA pre-assembled
Solar Radiation Shield).
Key Advantages:
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
