Site-Log Relative Humidity-Temperature Datalogger

Site-Log Relative Humidity-Temperature Datalogger

The Site-Log LRHT-1 is a single channel, battery powered, stand alone relative humidity and temperature data logger. The logger records up to 4 MB of data and stores it in non-volatile flash memory for later retrieval. It's fitted internally with a Sensiron RH Digital Sensor.

Featuring an aluminum enclosure and conformally coated PCB, the Site-Log data logger has excellent performance in the harshest industrial environment. Featuring a 16-bit ADC and programmable input range, the Site-Log data loggers are well suited to science and laboratory applications where precise and accurate measurement is critical.


  • Internal Relative Humidity and Temperature sensor
  • Internal temperature channel range: -40 to 70 °C
  • Relative humidity range: 0% to 100% (care must be taken against condensation in high humidity)
  • 12-bit Temperature and Humidity Readings
  • Temperature Accuracy: ±0.4 °C at 25 °C
  • Relative Humidity Accuracy:±3% (20% to 80% RH)
