testo 175H1 - 2 channel data logger

Saving energy, archiving, storing goods, creating a comfortable  indoor climate – if you can’t analyse the temperature and humidity, you  won’t get optimal results. The Testo 175H1 is designed to carry out  reliable long-term measurements and log these crucial values for you.  The Testo 175H1 continuously records temperature and humidity values  and, in addition to temperature and humidity, also shows the dewpoint in  the display if required. The indoor climate is thus monitored,  emphasizing the need for targeted ventilation and air exchange.

  • 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
  • Free software download (ComSoft Basic)

The testo 175H1 data logger measures, monitors and logs the  temperature and relative humidity in buildings and closed rooms. The  logger comes with an external humidity sensor (stub) for shorter  reaction times and a lock to prevent it from being easily stolen or  tampered with.

In addition to the current temperature and humidity  values, the logger can also log and display dew point values.  Other  information including adjustable threshold values, breached thresholds  and remaining battery power can also be read off the large, clear  display.

Security and comfort on all levels

The testo 175H1 ensures a high level of data security and reliable measurements based  on leading-edge technology. The logger has a super-size memory that can  save up to 1 million readings and an extended battery life of up to 3  years. This gives you the freedom to read out the data at longer  intervals, even when the measuring cycles are shorter. The triple AAA  batteries included in the scope of supply can be easily replaced by the  user.

Programming and Analyzing Your Data Loggers

Choose 1  of 3 software versions to program or read out your loggers or to  analyze the measuring data you have obtained on your PC:

  • Software ComSoft Basic - included - allows you to program your logger and analyze the data quickly and easily
  • Software ComSoft Professional - optional - provides you with additional possibilities and a more detailed analysis of the temperature and humidity values
  • Software ComSoft CFR 21 Part 11 - optional - ideal for the special demands of the pharmaceutical sector in compliance with 21 CFR Part 11

PLEASE  NOTE: You will need a USB cable (not included in scope of supply) to  program your data logger. The data can be transferred to your PC either  via USB cable or SD card. Both are optionally available as accessories  which can be ordered together with your testo 175 H1.

Areas of application for the testo 175H1 data logger

The  testo 175 H1 professional data logger is ideal for round-the-clock  monitoring of temperature and humidity values in closed rooms. The 175  H1 can monitor the indoor climate in buildings, storage facilities and  archives and help create a comfortable climate in the workplace. The  logger`s external humidity sensor (stub) is connected directly to the  housing for shorter reaction times.
