Monitor your environment quickly and easily with our waterproof data logger

A miniature, value-priced, waterproof data logger for temperature monitoring applications. The HOBO Pendant Temperature/Alarm Data Logger has one channel and is recommended for short-term shipping or long-term monitoring. This data logger features a visible LED light indicator that warns users when preset parameters have been exceeded. This model stores approximately 52K of 10-bit temperature readings. For accurate temperature measurement in sunlight, a solar radiation shield is required (assembly-required RS1 Solar Radiation Shield or pre-assembled M-RSA Solar Radiation Shield).

Features

• 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

Important Information

Requires HOBOware software and either an Optic USB Base Station or a HOBO Waterproof Shuttle (U-DTW-1). HOBOware Pro is required when using the HOBO Waterproof Shuttle. See Related Products below.
