This meter uses a sensor to start up.
The testo 176 T2 temperature logger is particularly suitable for reliable temperature monitoring on two channels. The data logger can accommodate two Pt100 probes of your choice, which you can order from our probes range. It is therefore possible to safely store temperature values from different measuring locations and, if required, compare them on site on the logger display.
You can carry out temperature monitoring over a longer period of time (eliminating the need for the data logger to be read out overly frequently). The testo 176 T2 temperature logger can store up to 2 million readings. Its battery life of up to 8 years also makes it practical for long-term temperature monitoring.
Technical features and practical benefits
The logger display offers you an overview of the current readings, limit values set and limit value violations, minimum and maximum values and also the remaining battery life. Thus, there is no need to read the data logger separately on your PC in order to quickly check it.
Data security is our top priority: you can rest assured that the measurement data stored in the temperature logger will not be lost. Data is not lost, even when the logger's battery is spent or while you are changing it.
The temperature logger is suitable for use in the food industry: it is certified to EN 12830 (tested by the ATP test station at TÜV Süd) and is HACCP-compliant. In compliance with protection class IP 65, the data logger is protected against water jets and can remain at the measuring location while cleaning is carried out there.
Possible areas of application for the temperature logger
- Temperature monitoring and documentation in storage facilities
- Temperature monitoring and documentation in deep-freeze storage areas, for example for foodstuffs
- Temperature monitoring and documentation in cold storage areas or in refrigerators, for example in pharmaceutical refrigerators
- Temperature logger as a reference for calibrating another temperature logger
Programming and analysis of the data logger
Programming and reading the data logger, as well as the analysis of measurement data, requires the use of a software package. Three different software versions are available:
- ComSoft Basic software – available as a free download – is ideal for fast programming of the temperature logger and easy data analysis
- ComSoft Professional software – also available – offers various options for carrying out detailed analysis of the temperature values
- ComSoft CFR 21 Part 11 software – also available – designed for applications in the pharmaceutical industry with its special requirements according to CFR 21 Part 11

Monitoring and documentation of the temperature in cold rooms
Many foods and drugs have to be stored within a specific cold temperature range. This can be done in individual cooled store rooms, but also in specialised cold stores or cold warehouses with high-rack facilities. The temperature must be continuously documented in all these cold storage facilities, because strict rules apply to quality management in both the food and drugs industries.
Data loggers are usually installed at the so-called critical control points (CCPs) of the cold room, in order to identify any possible temperature deviations and to introduce appropriate countermeasures. Critical points are for instance doors or passages through to other temperature areas within a warehouse.
Temperature monitoring in deep-freeze rooms for foods
There are a huge number of facilities where (deep-)frozen food has to be stored. These range from individual deep-freeze rooms on small food producers' sites (e.g. butchers), at restaurants and supermarkets, via deep-freeze rooms in the food industry, through to specialised cold stores / deep-freeze warehouses with high-rack facilities. The temperature must be continuously documented in all these facilities. In Europe, only temperature loggers may be used in this process which are approved according to EN 12830.
Typically, data loggers are used to measure the air temperature in storage facilities of this kind. The measuring instrument is installed in the deep-freeze room – as far as possible at critical points such as doors or cooling plants – and records the temperature data at defined intervals (typically: 15 minutes).
The recorded data can then be analysed and archived using special software.
Monitoring and documentation of storage temperature
Correct compliance with storage temperatures 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 temperature 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 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.
The use of external penetration probes means that the core temperature of goods can also be reliably monitored.
Monitoring and documentation of transport temperature
For all goods which react sensitively to temperature fluctuations or have to be stored within a predefined temperature range, uninterrupted measurement data recording and documentation play a major role.
Incorrect temperature 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 ranges and the data can then be read, analysed and archived by means of special software.
