Product Description

The testo 175 T1 data logger has a built-in temperature sensor and is ideal for monitoring and logging the temperature in cool and cold rooms as well as in storage facilities.
State-of-the-art technology. High level of data security
The temperature data logger’s display provides you with a wide range of valuable information including current measurement values, threshold values, points where these thresholds have been exceeded, min/max values and remaining battery power. And because all these values can be read off directly from the display, there is no need for you to boot up your PC. In addition, the data logger also has a super size memory, which can save up to 1 million measurements, and an exceptionally long battery life of up to 3 years. This gives you the freedom to read out the logger data at longer intervals, even when measuring cycles are shorter. The triple AAA batteries included in delivery can be replaced by the user.
Programming and analyzing your temperature data logger

Choose one of three software versions to program or read out your temperature logger or to analyze the measuring data you have obtained on your PC:

–  Software ComSoft Basic– available for free downloading – 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 values

–  Software ComSoft CFR 21 Part11– optional – ideal for the special demands of the pharmaceutical sector in compliance with 21 CFR Part 11

Monitoring and documentation of the temperature in cold storage rooms

Many foodstuffs or medicines have to be stored within a certain cold temperature range. This may be in individual refrigerated storage rooms, but also in specialised cold storage warehouses or high bay cold store warehouses. The temperature has to be documented in all of these refrigerated facilities, as strict regulations apply to quality management both in the food processing and medicine industries.
Data loggers are usually placed at the ‘Critical Control Points’ (CCPs) of a cold storage room to enable any fluctuations in temperature to be detected and appropriate action to be taken. Critical places include doors or passages into other temperature zones within a warehouse.

Monitoring the temperature in frozen food storage areas

There are many facilities where (deep) frozen foods need to be stored. These range from individual freezer rooms at small food manufacturers (e.g. butchers), restaurants and supermarkets, freezer rooms in the food processing industry, right through to specialised cold storage warehouses/high bay freezer warehouses. In all of these facilities, the temperature has to be documented continuously. In Europe, only temperature recording devices that comply with EN 12830 are allowed to be used.

Data loggers are typically used to measure the air temperature in these kinds of storage facilities. The measuring instrument is positioned within the freezer room at the critical places where possible, such as by doors or refrigeration units, where it records temperature data at specified intervals (typically: every 15 minutes).
With the aid of special software, the recorded data can consequently be analysed and stored.

Monitoring and documentation of storage temperatures

The proper observance of storage temperatures is an important prerequisite for the quality control of many products; e.g. in the area of foodstuffs and pharmaceutical products.
Data loggers are usually used for this purpose. They monitor and document the course of ambient temperature automatically, thereby contributing significantly to verifying that product quality is being maintained.
The direct display of violations of limit values allows fluctuations in temperature to be responded to fast. With the aid of the configuration and read out software, custom measurement configurations can also be made and recorded measurement data can be both analysed and stored.
