testo 174 H - Mini data logger for temperature and humidity
The testo 174 H - mini data logger for temperature and humidity is a compactly designed measurement solution that is particularly suitable for seamless monitoring of sensitive goods and climate control in buildings. Users who want to monitor food, archives or moisture-sensitive components benefit from its precise temperature and humidity sensors. Its long-lasting data memory for up to 16,000 measured values and its robust yet handy design clearly set it apart from many other devices on the market. Similarly sophisticated measurement functions can be found in the [testo 175 T1], for example, which impresses with temperature checks in the cold chain and is therefore used in comparable scenarios.
Powerful device for reliable measurements
The mini data logger offers a measuring range of -20 to +70 °C and therefore covers a wide range for temperature checks. The NTC temperature sensor technology is characterized by an accuracy of ±0.5 °C, which enables high-precision evaluations. When recording relative humidity from 0 to 100 %RH, the device impresses thanks to its capacitive sensor technology and a measuring accuracy of ±3 %RH (2 to 98 %RH). This ensures constant and reproducible measurement results even in critical environments. Those who require equally accurate but greater measurement cycle variability could consider the [testo 175 T2], which delivers similar reliability in humidity management.
Important key data at a glance:
- Temperature measuring range: -20 to +70 °C
- Measuring accuracy in the temperature range: ±0.5 °C
- Humidity measuring range: 0 to 100 %rh (not for condensing atmosphere)
- Humidity accuracy: ±3 %rh (2 to 98 %rh)
- Storage capacity: Up to 16,000 measured values
- Compact dimensions: 60 x 38 x 18.5 mm
- IP20 protection class for applications in dry environments
- Battery: 2 x 3V button cell (CR 2032), very easy to replace by the user
The powerful combination of temperature and humidity logger in one device predestines this mini data logger for several applications: from incoming goods inspection and warehouse monitoring to discreet home checks

Programming and evaluation options
To configure the data logger quickly, the manufacturer provides various software options. The free ComSoft Basic version enables clear programming and simple analysis of the recorded values. If you want to carry out more detailed evaluations or compare additional measuring points, you can upgrade to the ComSoft Professional software. The ComSoft CFR 21 Part 11 version, which is tailored to legal requirements such as CFR 21 Part 11, is also suitable for particularly regulated sectors such as the pharmaceutical industry.
The recorded data is easily transferred via a USB interface, which is required for readout and evaluation. One advantage is that all measured values remain securely stored even after an unexpected power failure. In contrast to many competitor products, the device therefore has integrated fail-safety in the event of a flat battery or during a battery change.
Norms and quality standards
Innovative measurement technology always goes hand in hand with compliance with strict guidelines: The data logger meets the requirements of EU Directives 2014/30/EU and 2011/65/EU. This ensures safe and standard-compliant work, especially in sensitive areas such as quality or process control.
Concrete application examples
- Maturing rooms in food processing: In order to check compliance with the cold chain or to guarantee certain maturing and fermentation conditions (e.g. for cheese or raw sausage), consistently accurate monitoring is crucial.
- Humidity-sensitive storage in archives: paper, antique books and historical drawings require a strictly regulated room climate to prevent damage from mold.
- Metal parts in the production area: Components susceptible to flash rust can be reliably protected from moisture damage by monitoring temperature and humidity development.
- Building monitoring: The device makes it easier to monitor indoor air humidity and temperature in rental properties. If values are outside the normal range, the feedback on ventilation behavior provides information before mould develops.
FAQs
How often can measurements be taken
?
The integrated measuring cycle can be configured from 1 minute to 24 hours. This allows flexible intervals that can be adapted precisely to the respective requirements.
What happens when the battery is empty
As soon as the battery runs out, all measured values that have already been recorded remain safely stored. There is no data loss during and after the battery change.
Is the device suitable for high humidity environments?
The logger is generally suitable for 0 to 100 %RH, but not for dewy atmospheres or long-lasting humidity levels above 80 %RH at ≤30 °C. In the event of heavy continuous use in high humidity, advice should be sought to prevent damage to the device.
How can I read out the data?
A suitable USB interface is required to quickly transfer the data to a PC. There, the evaluation is carried out as required using one of the ComSoft Basic, Professional or ComSoft CFR 21 Part 11 software solutions.
In which areas can the logger be stored?
When switched off, the logger can withstand storage temperatures between -40 and +70 °C. This means that the device can also be stored outdoors or in cooled storage rooms without any problems.
Conclusion
The testo 174 H - Mini data logger for temperature and humidity scores with a successful combination of compact design, high storage capacity and precise sensor technology, which opens up many possible applications in the field of professional temperature and humidity monitoring. Thanks to fail-safe data storage, replaceable standard batteries and versatile evaluation software, nothing stands in the way of reliable documentation. If you don't want to compromise on sensitivity and data security, this clocked mini data logger is a powerful partner for precise and standard-compliant monitoring.
