testo 175 H1 - Temperature and humidity data logger

Order-Nr.  0572 1754

  • Dual measurements (1 internal, 1 external)
    for ambient temperature & humidity monitoring 

  • Large memory, 1 Million Readings 

  • Data transfer possible using the USB port
    or SD card (Optional) 

  • Free data logger software available for download 

The Testo 175H1 is a compact professional data logger for monitoring of Temperature, Humidity & Dew Point.The external temperature & humidity probe creates faster reaction times in comparison to other temperature & humidity data loggers that are available in the market. 

Product Description

The 175 H1 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.

Security and comfort on all levels

The 175 H1 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 analysis with the temperature data logger

You need software for programming and reading your temperature data logger and analyzing measurement data on the PC. We offer three different software versions for you to choose from:
  • ComSoft Basic software – available as a free download – enables fast programming of the data logger and easy measurement data analysis
  • ComSoft Professional software – available as an option – offers a variety of possibilities for detailed analysis of measurement results
  • ComSoft CFR 21 Part 11 software – available as an option – can be used for special requirements according to CFR 21 Part 11 in the pharmaceutical sector

Monitoring and documentation of building air conditioning

Temperature and relative humidity are crucial factors in assessing air quality and levels of comfort in indoor spaces, e.g. in workplaces. With the aid of data loggers, this data can be permanently monitored and documented.
They are also excellently suited to the monitoring of ventilation systems or for assessing existing building moisture.
With the use of special software, the measurement configurations can be customised and recorded measurement data can be both analysed and stored.

Monitoring and documentation of the storage temperature and humidity

The proper observance of storage temperature and humidity is an important prerequisite for the quality control of many products; e.g. in the area of food and pharmaceutical products.
To this end data loggers are usually used. They monitor and document the course of ambient conditions automatically, thereby contributing significantly to verifying that product quality is being maintained.
The direct display of violations of limit values allows fluctuations in temperature and humidity to be responded to fast. With the aid of the configuration and read out software, custom measurement configurations can also be made and recorded measurement data can be both analysed and stored.

Monitoring and documentation of the transportation temperature and humidity

The smooth recording and documentation of measurement data plays a significant role for all products that are sensitive to temperature and humidity fluctuations, or which need to be stored in a predesignated area.
The wrong conditions during transportation can result in major losses in quality right through to a complete loss of value for the monitored products.
With the aid of a data logger, goods in transit can be monitored to make sure specified temperature and humidity zones are being observed; this can then be read out, analysed and stored using special software.
