  • 4 Channel measurements (2 External probes) for external temperature/Humidity monitoring 

  • Ability to measure Temperature & Humidity simultaneously 

  • Large memory, 2 Million Readings 

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

The data logger testo 176 H1 allows the monitoring of temperature and humidity in warehouses and buildings. With the testo 176 H1, you can examine whether mould in a house or apartment has been caused by insufficient ventilation or by building damage.


Professional software with Excel export function for programming the logger and data analysis.


Product Description

The Testo 176H1 is a four channel temperature humidty data logger that has two connections for external humidity probes which can be located according to individual requirements. The large display can show both temperature and humidity at the same time. The Testo 176 H1 comes with display, which enables the user to easily read temperature, humidity & dew point.

The Testo 176 H1 is the perfect data logger for analyzing precise climatic development using long-term measurements.

Two external humidity/temperature probes, which you can order when you purchase the climate data logger, can be attached to it. This will enable you to measure temperature and humidity at two different points simultaneously.

With its large memory up to 2 million readings and its long battery life up to 8 years the data logger is the ideal instrument for the long-term recording of climate data.

Possible areas of application for the humidity logger

  • Monitoring and documentation of the air conditioning in buildings
  • Monitoring and documentation of the temperature and humidity in production and in warehouses

Programming and analysis of the data logger

Programming and reading the data logger, as well as the analysis of measurement data, requires the use of a software package. Three different software versions are available:
  • ComSoft Basic software – available as a free download – is ideal for fast programming of the temperature logger and easy data analysis
  • ComSoft Professional software – also available – offers various options for carrying out detailed analysis of the temperature values
  • ComSoft CFR 21 Part 11 software – also available – designed for applications in the pharmaceutical industry with its special requirements according to CFR 21 Part 11

Monitoring and documentation of building climate

Temperature and relative humidity are crucial factors when it comes to assessing air quality and comfort levels in indoor areas, e.g. in workplaces. Both values can be monitored and documented over the long term using data loggers.
They are also very well suited for checking ventilation systems or for assessing any building moisture which occurs.
The use of special software means measurement configurations can be carried out individually and recorded measurement data can be both analysed and archived.

Monitoring and documentation of storage temperature and humidity

Correct compliance with storage temperature and humidity is an important prerequisite for the quality assurance of many products, e.g. in the area of food and pharmaceutical products.
As a general rule, data loggers are used to do this. They automatically check and document the profile of the ambient conditions and thus make a crucial contribution to verifiable preservation of product quality.

Viewing breaches of limit values directly on the display means you can respond quickly to temperature and humidity deviations. In addition, with the help of the configuration and read-out software, customer-specific measurement configurations can be carried out and recorded measurement data can be both analysed and archived.
