HOBO S-THC-M002 12-bit Temperature/Relative Humidity Smart Sensor (2m cable)

For the full specifications for this product, please see the product manual found under the Resources tab.

Measurement Range

Temp: -40°C to 75°C (-40°F to 167°F)
RH: 0-100%* RH at -40° to 75°C (-40° to 167°F); exposure to conditions below -20°C (-4°F) or above 95% RH may temporarily increase the maximum RH sensor error by an additional 1%

Accuracy

Temp: ±0.25°C from -40° to 0°C (±0.45°F from -40° to 32°F); ±0.20°C from 0° to 70°C (±0.36°F from 32° to 158°F); ±0.25°C from 70° to 75°C (±0.45°F from 158° to 167°F)
RH: ±2.5% from 10% to 90% RH (typical), to a maximum of ±3.5% including hysteresis at 25°C (77°F); below 10% and above 90% ±5% typical

Resolution

Temp: 0.02°C
RH: 0.01% RH

Bits Per Sample
Temp: 16
RH: 16

Drift
Temp: < 0.01°C (0.18°F) per year
RH: < 1% per year typical

Response Time (typical, to 90% of change)

Temp: Without solar radiation shield: 3 minutes, 45 seconds in air moving 1 m/s; With RS3-B solar radiation shield: 6 minutes, 30 seconds in air moving 1 m/s
RH: Without solar radiation shield: 15 seconds in air moving 1 m/s; With RS3-B solar radiation shield: 30 seconds in air moving 1 m/s

Operating temperature range: -40°C to 75°C (-40°F to 167°F)
Environmental rating: Weatherproof: 0 to 100% RH intermittent condensing environments. For best results, protect the Temp/RH sensor from sunlight and direct splashing by mounting it inside a protective enclosure, such as a solar radiation shield.

Housing: PVC cable jacket with ASA styrene polymer RH sensor cap; modified hydrophobic polyethersulfone membrane
Sensor dimensions: 45.97 x 11.43 x 10.16 mm (1.81 x 0.45 x 0.40 inches)
Weight: 110 g (3.88 oz)
Number of data channels**: 2
Measurement averaging option: No
Cable lengths available: 2.5 m (8.2 ft)
Length of Smart Sensor network cable: 0.5 m (1.6 ft)

*   Maximum 100% RH readings are only logged with RX3000 stations. The maximum readings for this sensor with U30 and H21 stations are approximately 99.99%.

**  A single HOBO station can accommodate 15 data channels and up to 100 m (328 ft) of smart sensor cable (the digital communications portion of the sensor cables).
