Relative Humidity & Temperature Sensors
Relative humidity sensors are electronic devices often paired with an RTD, thermistor, or transmitter to provide both temperature and relative humidity readings to measure the amount of moisture present in the air relative to the maximum humidity for precise air quality monitoring and control. They are commonly integrated into HVAC and BAS systems to optimize energy consumption and reduce costs.
DUCT MOUNT RH SENSOR
AcuHUM DM
The AcuHUM DM duct-mounted sensor provides accurate RH and optional temperature measurement with thermistor, RTD, or transmitter options. It features fast response, low long-term drift, and built-in temperature compensation for ±2% RH accuracy. Housed in an IP65-rated enclosure, it includes an adjustable probe with a secure mounting flange, making it ideal for HVAC duct applications.
ROOM MOUNT RH SENSOR
AcuHUM RM
This room-mounted relative humidity sensor, with optional temperature sensor, is designed for surface or junction box installation and features a four-way aspiration enclosure. Temperature sensing options include thermistor, RTD, or transmitter types, while the RH output is available in either 4–20 mA or 0–10 VDC. The AcuHUM RM integrates seamlessly with building automation systems to help control indoor air quality via economizers, fans, and other HVAC components.
OUTDOOR AIR RH SENSOR
AcuHUM OA
The AcuHUM OA outdoor relative humidity sensor delivers long-term stability, fast response time, and reliable recovery from condensation. Designed for vertical surface mounting, it monitors both outdoor RH and temperature. Housed in an IP65-rated enclosure, the sensor is protected against dust and water ingress. Optional thermistor, RTD, or transmitter configurations allow for combined temperature and humidity measurement in a single device.
OUTDOOR AIR RH SENSOR
AcuHUM OAW
The AcuHUM OAW outdoor humidity and temperature sensor is IP65-rated and equipped with a six-layer weather shield for enhanced protection against solar radiation, rain, and dust. The shield’s natural ventilation minimizes the thermal effects of UV exposure, enabling faster response times and more accurate long-term measurements. The sensor offers optional thermistor, RTD, or transmitter configurations to deliver both temperature and RH readings in a single device.
