Stowaway and Optic Stowaway Dataloggers

The StowAway and Optic StowAway family of dataloggers are powerful, miniature, battery-operated instruments for continuous temperature, relative humidity and light intensity monitoring. All loggers feature: push button triggered start for launching in the field, programmable delayed launch of up to three months, alarm indications and extended EEPROM memory ranges (StowAway 2K, 8K or 32K, Optic StowAway 8K, 32K).

Optic StowAway loggers use Infra-Red technology to replace jacks and cables for communications. This allows all Optical StowAway loggers to be completely sealed and waterproof for underwater applications. Optical communications makes data transfer quicker and easier even in wet and dirty locations.

StowAway XTI Temperature Loggers

Each StowAway XTI Datalogger is a dual purpose temperature logger that includes an internal sensor and a jack for using with an external temperature sensor. When used, the external sensor overrides the internal sensor, increasing the versatility of the logger. Uses replaceable battery. Two temperature ranges are available and reads in C and F, best accuracy: 0.2 C. Dimensions: 1.8" x 1.9" x 0.6".
