The testo 174 allows you to monitor temperature and humidity sensitive goods – including foods, archives or metal parts that are susceptible to surface rust – or carry out discreet humidity checks in buildings to ensure that the property is being properly looked after by the tenants.
The testo 174 mini data logger has built-in longlife sensors 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.
Practical: The standard batteries (2x CR 2032) included in the scope of supply can be easily replaced by the user.
Programming and Analyzing Your Temperature and Humidity Data Logger
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
You will need a USB interface to program and read out your mini data logger.
