The Testo 174H Set is a two channel temperatrue and huimidty data logger. It is a low cost compact data logger ideally suited to monitor conditions in living, work & storage rooms. It is mainly used in occupational helath and safety, Indoor air quality, Heating, Air conditioning & Refrigeration industries. 

Product Description

Does your work involve the warehousing or storage of climate-sensitive items (food, drugs, archive media, museum exhibits, metal parts susceptible to rust film, etc.)? Or would you like to keep a check on the building climate, for example monitoring how your tenants use ventilation? Then continuous recording of temperature and humidity readings can be very useful for you. The testo 174H mini data logger for temperature and humidity provides you with competent support for this kind of measurement task. It may be small, but it achieves great (measurement) results.

This is what the mini data logger for temperature and humidity offers

The current measuring values and any possible violations of limit values can be read on the mini data logger’s display. Its measurement data memory can reliably record up to 16 000 measuring values. Saved measurement data will not be lost even when the battery is empty or being replaced.
The testo 174H mini data logger has internal sensors which measure temperature and humidity. The humidity sensor is a capacitive Testo humidity sensor with long-term stability which has an accuracy of up to ±3 % RH when measuring humidity. With an accuracy of ±0.5 °C, the internal NTC temperature sensor is particularly high-precision and covers a measuring range from -20 to +70 °C.
Particularly practical: the mini data logger runs on standard batteries (2x CR 2032) which you can replace yourself at any time.

Programming and analysis with the data logger for temperature and humidity

Software is used to programme and read your mini data logger as well as to analyze measurement data on the PC. You have a choice of three software versions:
  • ComSoft Basic software – available as a free download – for fast programming of the mini data logger and easy analysis of measurement data
  • ComSoft Professional software – can also be ordered as an option – offers a variety of possibilities for detailed analysis of temperature and humidity readings
  • ComSoft CFR 21 Part 11 software – can also be ordered as an option – the best solution for special requirements according to CFR 21 Part 11 in the pharmaceutical sector

Advantage of the set: the mini data logger is ready to use straight away

A USB interface is needed to programme and read your mini data logger for temperature and humidity. If you decide on this set, it includes a USB interface which means a speedy start for your measuring tasks.

Attention: Please download the newest software version before using the USB interface for the first time. The software can be found in the download area.

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.
