Product Description

The Testo 174H Mini humidity data logger is an ideal device for people who are required to monitor Temperature and Humidity in a single device. It incorporates the Testo patented humidity sensor proven worldwide at an affordable price. Thanks to the one - button menu structure - a click on the "GO Button" activates the data logger for up to one year at a 15 minute recording cycle.

The testo 174 H allows you to monitor temperature and humidity sensitive goods – including in food, archives or in machines, susceptible to rust –

The testo 174 H mini data logger has built-in long life sensor that can measure the temperature and humidity of the surrounding environment, a memory for up to 16,000 measurements and an easy-to-read display that shows the current reading as well as any breached thresholds.  

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.
PLEASE NOTE: THE 174H REQUIRES A SPECIAL TESTO USB INTERFACE TO OPERATE INSTRUMENT (THIS CONNECTS LOGGER TO PC) IF THIS IS YOUR FIRST PURCHASE OF A TESTO 174H YOU WILL NEED TO ORDER THE 174H SET FIRST. THE SET INCLUDES 1 DATA LOGGER AND THE USB INTERFACE.

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.

Monitoring and documentation of transport temperature and humidity

For all goods which react sensitively to temperature and humidity fluctuations or have to be stored within a predefined range, uninterrupted measurement data recording and documentation play a major role.
Incorrect conditions during transport can lead to major losses of quality, including the total loss of value of the products that require monitoring.

Using a data logger, shipments can be checked for compliance with the specified temperature and humidity ranges and the data can then be read, analysed and archived by means of special software.
