HOBO Temperature/Relative Humidity Intrinsically Safe Data Logger
This product is compatible with Boxcar, which is discontinued. However, users of our legacy products can still download the unsupported free version below:
An intrinsically safe two-channel data logger with internal temperature and relative humidity (RH) sensors, this model has a rugged housing designed for years of reliable use in outdoor applications. This model offers high accuracy, 8- or 12-bit resolution settings, and 64K of memory for long-term deployments. The model's RH sensor is designed for use in outdoor environments with cyclical high- and low-humidity levels This model is rated intrinsically safe (US standards): IS, Class I, II, Division 1, Groups A-G, Temperature Code T4 (≥135°C); NI, Class I, Division 2, Groups A-D, Temperature Code T4 (≥135°C); S, Class II, Division 2, Groups F and G as specified in the US Electric Code and approved by Factory Mutual.
- Certified instrinsically safe for monitoring hazardous locations where combustible gas and/or dust may be present
Operating range (logger): -30°C to +50°C (-22°F to +122°F), 0 - 100% RH, HOBO Pro RH/Temp IS 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 dependence 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
Data offload time: 1 minute typical
Size: 4.0" H x 3.2" W x 2.0" D
Weight: approx. 3.7 oz.
Battery: Tadiran TL-5902, lithium, (3.6V 1.2Ah), 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)
Intrinsically Safe Rating: IS, Class I, II, Division 1, Groups A-G, Temperature Code T4 (<135oC); NI, Class I, Division 2, Groups A-D, Temperature Code T4 (<135oC); S, Class II, Division 2, Groups F and G
