This miniature data logger can record temperature and relative light levels. Complete with waterproof casing, this product is designed for indoor, outdoor, and underwater deployment. This model can store approximately 52,000 measurments 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 radiation shield prevents the use of the light sensor. 

Highlighted 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
