FEATURES
Guarantee a measurement accuracy of ± ±3 Rꢀ in the humidity range of 5 to 953 Rꢀ.
They are highly accurate. The nominal accuracy for the CꢀSUPR and CꢀR-UPS is within ± ±(3) Rꢀ.
Characteristics are stable over a wide temperature range.
Dry and wet characteristics exhibit virtually no hysteresis.
ꢀighly cost-effective and compact, requiring extremely little mounting space.
Low current consumption.
Outputs DC.1V at 100(3)Rꢀ; relative humidity can be read directly with a voltmeter.
All-in-one construction integrates sensor with support circuitry. The entire module operates off a 5V power supply.

Handling Precautions
For all CHS Series products
Please request the delivery specification form containing more detailed information on characteristics and specifications, so as to ensure correct
and safe use of the products.
Operating life of the products becomes shorter depending on the environmental conditions. If you place emphasis on the stable operation period, please
confirm the operating life in the actual environment in advance.
[Storage Environment]
Check the standards concerning the storage conditions described in the delivery specifications of the products, and store them in accordance with
the standards.
It is recommended that the products be stored in an airtight container with silica gel.
Avoid storing the products in environments in which corrosive gases are generated, enter, or stagnate, or in dusty environments.
Storage in high temperature and high-humidity environments, environments where dew condensation occurs, or environments where sudden tem-
perature changes may cause deterioration of the moisture sensitive film, resulting in fluctuations of output exceeding the guaranteed range. If the
products have been stored in such environments, check their characteristics before use.
Storage in environments where products may come into contact with water or saltwater may cause deterioration of the moisture sensitive film,
resulting in fluctuations of output exceeding the guaranteed range. If the products have been stored in such environments, check their characteris-
tics before use.
Storage for an extended period of time may cause deterioration of the moisture sensitive film, resulting in fluctuations of output exceeding the guar-
anteed range. If the products have been stored for an extended period of time, check their characteristics before use.
[Usage Environment/Operating Conditions]
As for operating conditions and operating conditions of the products, check the standards concerning the operating conditions described in the
delivery specifications, and use the products in accordance with the standards.
Generation, influx, or stagnation of corrosive gases or a large amount of dust may become a cause of deterioration of the moisture sensitive film,
resulting in fluctuations of output exceeding the guaranteed range.
ꢀigh temperature and high humidity, dew condensation, or sudden temperature changes may become a cause of deterioration of the moisture
sensitive film, resulting in fluctuations of output exceeding the guaranteed range.
Environments where the products come into contact with water or saltwater may become a cause of deterioration of the moisture sensitive film,
resulting in fluctuations of output exceeding the guaranteed range.
[Product Handling]
Do not apply excessive mechanical shock to the products, such as dropping.
Do not cover the sensor face of the products when mounting.
Pay attention not to apply excessive stress on the main unit when forming terminals.
In processes in which a flux decomposition gas is generated, such as flow soldering, take measures to prevent corrosive gases from entering into
the product, such as applying a temporary seal on the opening of the main unit (corrosive gases may become a cause of deterioration of the mois-
ture sensitive film, resulting in fluctuations of output exceeding the guaranteed range).
Element type
[Usage Environment/Operating Conditions]
The rated voltage of this product is Eac 5 V max. Please be reminded that serious damage including electrolysis or peeling of the moisture sensitive mate-
rial may occur if a direct current is applied to the products. In addition, please keep in mind that there may be similar impacts that occur in the case of
direct current application will occur even when applying an alternating current, due to (1) residual direct current or (2) asymmetrical waveforms.
Other Requests/Notices
We will not assume any responsibility for damage caused by use outside the ranges or conditions defined in the delivery specifications.
Specifications of the products in this catalog are subject to change without notice, due to improvements or other reasons. In addition, supply of the prod-
ucts may be canceled without notice.
Please be sure to request delivery specifications that provide further details on the features and specifications of the products for proper and safe use.
Please note that the contents may change without any prior notice due to reasons such as upgrading.
