The Testo 174H Temperature and Humidity Mini Data Logger can be used to monitor the air temperature and humidity surrounding sensitive goods such as food, archives and metal parts prone to rusting. It can also be used to monitor the humidity of buildings.
The Testo 174H Temperature and Humidity Mini Data Logger is equipped with long-life temperature and humidity sensors with the following measurement ranges:
These sensors are designed to ensure the Testo 174H Temperature and Humidity Mini Data Logger’s accuracy and reliability over long periods of time. These sensors, combined with the data logger’s secure, state-of-the-art measurement technology, means that the user is able to adhere to quality assurance guidelines.
Data is logged to the Testo 174H Temperature and Humidity Mini Data Logger’s extensive memory; it has the capacity to store up to 16 000 measurements. Readings can be viewed via the Testo 174H Temperature and Humidity Mini Data Logger’s large, easy-to-read display; it is possible to view the current temperature and humidity measurements, as well as any breached thresholds via this display.
Measurements can be transferred to a PC for further analysis via an additional USB cradle interface (sold separately). It is also possible to log data to the PC using this interface. The Testo 174H Temperature and Humidity Mini Data Logger can be used with Testo’s ComSoft Basic Software (available for free download) to analyse logged data. This software can also be used to configure the Testo 174H Temperature and Humidity Mini Data Logger in accordance with the user’s requirements.
Alternatively, the Testo 174H Temperature and Humidity Mini Data Logger can be used with Testo’s ComSoft Professional Software (sold separately) in order to conduct more comprehensive data analysis. The Testo 174H Temperature and Humidity Mini Data Logger is also compatible with Testo’s ComSoft CFR 21 Part 11 Software (sold separately) specifically designed for the pharmaceutical sector.
The Testo 174H Temperature and Humidity Mini Data Logger is a compact, complete, customisable data logging thermometer and hygrometer. It can be used to measure air temperature and relative humidity in storage rooms and offices.
