Data Logger 175-H1

The logger 175-H1 is a compact and small sized data logger, which measures temperature and humidity with a memory up to 1 million results. The logger provides immediately a quick overview of the current reading, the last value saved, maximum and minimum value and the number of times the limit has been exceeded. The measurement data are retained even when the batteries are empty or when changing batteries. Data loss is almost impossible.

  • Round-the-clock monitoring and logging of temperature, relative humidity and dew point
  • Super-size memory for long-term measurements and up to 1 million readings, battery life 3 years
  • Shorter reaction times and accurate measurements with external humidity sensor


  • industrial processes
  • domestic housing
  • offices
  • warehouses
  • museums
