Our humidity sensors use cutting-edge capacitive, resistive, and thermal conductivity measurement technologies to detect relative humidity and air temperature with high accuracy. Each sensor is factory-calibrated, tested for drift and linearity, and engineered for long-term field stability. This ensures trustworthy data collection for applications that require consistent and traceable results.

Recent advancements in smart sensor technology have enabled ProfEC Ventus to offer models equipped with integrated microprocessors and real-time data logging. These intelligent humidity sensors can automatically record and transmit data via wired or wireless networks (Wi-Fi, Bluetooth Low Energy, Zigbee or Modbus RTU/TCP), enabling remote monitoring and predictive maintenance. They can send alerts when thresholds are exceeded and store data locally or in cloud platforms for later analysis.

Key advantages of ProfEC Ventus humidity sensors:

  • High accuracy and stability in long-term deployment
  • Fast response and recovery after condensation or chemical exposure
  • Robust IP-rated housing for outdoor and industrial environments
  • Optional temperature integration for full climate data collection
  • Compatibility with most data loggers and SCADA systems

In climate and environmental research, our sensors help monitor relative humidity in greenhouses, weather stations, and hydrological measurement networks. In industrial settings, they ensure product quality and process safety in sectors like food processing, pharmaceuticals and electronics manufacturing. For HVAC applications, they support energy-efficient building management by maintaining ideal indoor air conditions.

ProfEC Ventus offers these humidity and temperature sensors as part of complete measurement solutions with data loggers and software for visualisation and analysis. All devices are backed by our in-house testing and calibration services to ensure reliable operation over the sensor’s lifetime.
