The testo 175T1 temperature data logger features a large display and alarm indication that makes it ideal for continuous monitoring of storage temperature. The temperature measurement logger is ideal for dependable temperature monitoring in refrigerated and deep freeze rooms for extended periods of time. Creation of Excel Spreadsheets, PDFs, and data analysis are all easily achieved with the free, downloadable ComSoft software. Please note: The testo 175T1 temperature measurement logger requires an interface to use the free data logger software. One interface can be used for multiple instruments. 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 specialized 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 specialized 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 analyzed 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 analyzed and stored.
