Intermountain Environmental, Inc. | - HOBO Pendant Temperature Logger with Alarm

miniature one-channel temperature logger, this model is waterproof and value-priced for short-term shipping applications or year-long remote deployment. 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 8K model stores approximately 6.5K of 10-bit temperature readings
