VaiNet Wireless Humidity and Temperature Data Logger RFL100

The RFL100 data logger uses Vaisala’s proprietary VaiNet wireless technology to monitor environments ranging from warehouses, to production areas, to cleanrooms and laboratories. The loggers connect wirelessly to Vaisala’s monitoring system: the viewLinc Enterprise Server, which provides real-time trends, alarms, and historical  reporting. The VaiNet wireless technology is based on the LoRa® modulation technique to provide a robust wireless signal that is extremely reliable over long distances and in complex, obstructed conditions.

  • Industry-leading temperature and relative humidity measurement precision
  • Detachable high-accuracy RH and temperature probes
  • Magnetic mounting bracket available
  • Typical battery life of 18 months, no need for costly battery replacements between recommended calibrations
  • Each data logger uses standard alkaline batteries


Detachable Probe

RFL100 supports several probe types for humidity and temperature measurement. The probes use Vaisala HUMICAP humidity sensors and platinum temperature sensors (Pt100 and Pt1000 type) for superior stability. Probes can be integrated with the RFL100 housing or connected using a cable. The probe is detachable, and easy to switch out for calibration. viewLinc Enterprise Server detects the changed probe information automatically and maintains accurate and complete historical records.
