  • Product Name:HOBO 64K Pendant® Temperature/Alarm (Waterproof) Data Logger
  • Item No.:UA-001-64
  • Manufacturers:Onset
  • Country of Origin:US

Overview

A miniature, waterproof one-channel temperature data logger, this model is value-priced for short-term shipping applications or long-term 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).

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
