HOBO Temperature Data Logger

Part # H08-030-08
This product is discontinued.


Effective immediately Onset will no longer manufacture the original H08-03x HOBO Pro family of loggers. The reason for this change is that we are no longer able to get a chip that is a critical part of being able to make the H08-03x-08 loggers. The recommended upgrade is our newer U23 series data loggers.

Upgrade to the Next Generation U-Series Loggers

RH Sensor operating environment: 0°C to +50°C (+32°F to +122°F) in intermittent condensing environments up to +30°C; and above +30°C in non-condensing environments.
Sensor requires protection from rain, splashing, mist, dust, and airborne chemicals such as salt and ammonia.
Time accuracy: approx. ±1 minute per week (±100 ppm at +20°C or +68°F), full dependance shown in manual.
Measurement capacity: 65,291 standard-resolution (8-bit) measurements, 32,645 high-resolution (12-bit) measurements or 21,763 measurements if one channel uses standard-resolution and the other channel uses high-resolution. RH measurements use standard resolution only. All measurements are stored in nonvolatile memory, with seven levels of data archiving (See Non-Volatile Memory).
Data offload time: 1 minute typical
