ACI A/RH1-R Room Humidity Transmitter 1% MA/VDC

The ACI Relative Humidity Room Series uses a durable capacitive sensing element with a hydrophobic filter to resist moisture, dust, dirt, oils, and chemicals. It offers flexible setup with selectable output signals via DIP switches and can run on AC or DC power. Users can perform simple field calibration in ±0.5% increments. The sensors are designed for long-term reliability without needing replacement, come in two enclosure styles with four-way airflow to reduce self-heating. Common applications; Humidification, Dehumidification, Monitoring Indoor Space Humidity, Clean Rooms, Hospitals, Process Control, Laboratories, Museums, Schools, Office Buildings, Data Centers, and ESD(Anti-static) Control.
