The ACI Relative Humidity (RH) Room Series is a line of sensors designed for various applications where monitoring and control of humidity levels are necessary. These sensors are equipped with a thermoset polymer capacitive sensing element, which provides accurate humidity measurements. The sensing element has a factory-fitted hydrophobic filter, enhancing its resistance to moisture.

The multilayer construction of the sensing element ensures excellent resistance to dust, dirt, oils, and common environmental chemicals. This feature makes the RH room sensors suitable for environments where such contaminants are present.

The RH room sensors are equipped with on-board DIP switches, allowing users to select the desired output signal. Additionally, these sensors can be powered by either AC or DC power sources, providing flexibility in installation.

For calibration purposes, the sensors feature increment and decrement calibration DIP switches. By toggling these switches, the user can perform single point field calibration, adjusting the humidity curve up or down in +/- 0.5% increments. This calibration method eliminates the need to replace the sensors in the field and ensures long-term reliability.

The RH room series offers two enclosure options, designed to complement various commercial decors. Both enclosures feature four-way airflow, which minimizes self-heating and helps maintain accurate readings.

The applications for the ACI RH Room Series include:

• Humidification and Dehumidification: These sensors can be used in systems that control humidity levels, ensuring optimal conditions for comfort or specific processes.
• Monitoring Indoor Space Humidity: The sensors provide continuous monitoring of humidity levels in indoor spaces, allowing for adjustments and maintaining a comfortable environment.
• Clean Rooms: In clean room environments, precise humidity control is crucial for maintaining the integrity of sensitive processes and materials.
• Hospitals: The RH room sensors can be used in hospitals to monitor and control humidity levels, contributing to patient comfort and preventing the growth of harmful microorganisms.
• Process Control: Industries that rely on specific humidity levels for manufacturing or other processes can benefit from these sensors for accurate monitoring and control.
• Laboratories: Research and testing laboratories often require precise humidity control to ensure accurate results and maintain the integrity of samples.
• Museums: Maintaining proper humidity levels is essential for preserving delicate artifacts and artworks in museums.
  Schools and Office Buildings: The sensors can help create a comfortable and productive environment for students and employees by regulating humidity levels.
• Data Centers: Data centers need to maintain stable humidity levels to prevent equipment damage and ensure optimal performance.
• ESD (Anti-Static) Control: In environments sensitive to electrostatic discharge, monitoring and controlling humidity can help mitigate ESD-related risks.
