Product Description

With the testo 174 H tiny data logger, you may discreetly examine the humidity levels in buildings or monitor temperature and humidity-sensitive items like food, records, or metal elements that are prone to surface rust.
The mini data logger is equipped with long-lasting built-in sensors that can measure the temperature and humidity of the immediate environment. It also has a memory that can store up to 16,000 measurements and an easy-to-read display that shows both the current reading and any thresholds that have been crossed.
The logger comes with two ordinary batteries (2x CR 2032), which the user can quickly swap out.

Testing 174 H: Setting Up and Examining the Temperature and Humidity Micro Data Recorder

To configure or read out this small data logger, or to examine the measuring data you have obtained on your PC, select one of three software versions:

You may quickly and easily program  the data logger using the bundled ComSoft Basic software.

ComSoft Professional software, which is optional, gives you more options and a more in-depth study of the temperature and humidity values

ComSoft CFR 21 Part 11 software is appropriate for the unique requirements of the pharmaceutical industry and complies with 21 CFR 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.

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.
