S-THC-M008 Temperature/Relative Humidity (8m cable) Smart Sensor

Features

    Smart Sensor
    Works with all loggers that accept Smart Sensor inputs
    Automatically communicates configuration data to the logger

Specifications
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

Sensor

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

Weight
    180 g
    6.35 oz
Number of data channels**
    2
Measurement averaging option
    No
Cable lengths available
    8 m
    26.2 ft
Length of Smart Sensor network cable
    6 m (19.6 ft).

Notices
    * 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).
