HOBO External Input Temperature Data Logger

Part # H14-002
This product is discontinued.

Upgrade to U14-002


The HOBO LCD two-channel data logger has LCD readout and alarm capability, and requires an external probe for operation. Temperature probes can be used underwater, and the Temperature probe is suitable for intermittent condensing environments. An alarm display and built-in relay for use with Onset's Remote Alarm and/or Autodialer accessories assure timely notification of alarm conditions. A Protective Case is available for mounting in condensing environments.
