Onset will no longer manufactures the H08-03x HOBO series loggers. The recommended upgrade is the HOBO Pro v2 series data loggers.

Environment:

The H08-032-08 Data Logger is for use in Outdoor environments

Measurements:

The H08-032-08 Data Logger supports the following measurements : Temperature, Relative Humidity

Operating range (logger): -30°C to +50°C (-22°F to +122°F), 0 - 100% RH, HOBO Pro RH/Temp should be mounted so that water does not impact or collect in the RH sensor.

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 Plot A. Time Accruacy Full Dependence

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 section in the manual).

Data offload time: 1 minute typical

Size: 4.0" H x 3.2" W x 2.0" D

Weight: approx. 3.7 oz.

Battery: 1/2 AA, lithium, 3.6V, user-replaceable (Use only Onset part # HP-B)

Battery life (continuous use): 3 years

Storage temperature: -30°C to +75°C (-22°F to +167°F)
