Are the specified temperature limit values also maintained in the process? Find out with the testo 176 T4 temperature data logger. It measures the temperature values at up to four points simultaneously, records them reliably and can store up to 2 million readings. This means that longer intervals between individual readings are also possible.
You need at least one temperature sensor to commission the data logger. A variety of thermocouple sensors are optionally available - type K, type T or type J, for immersion/penetration, air or surface measurement.
Technical features and practical benefits
Current measured values, set limit values and limit value violations, minimum and maximum values and the remaining battery time can be read off the display at any time. This means you do not necessarily have to read out the device via the PC for a quick overview of the data. Thanks to the large measurement data memory and the battery life of up to 8 years, you generally have to read out the data much less frequently, even with shorter measuring cycles.
Thanks to protection class IP 65, theesto 176 T4 data logger can be used in dirty, dusty environments without any problems and the standard batteries (AA) can be easily replaced by the user at any time.
Temperature monitoring in freezers or under cryogenic conditions
Measurement and documentation of flow and return temperatures at the distributor of underfloor heating to ensure functionality
Checking process temperatures
Checking the flow and return temperatures of heating systems
Programming and evaluating the data logger
You can choose between three software versions for programming and reading out your data logger and evaluating the measurement data on the PC:
ComSoft Basic software - available as a free download - for quick programming of the data logger and simple data analysis
ComSoftProfessional software - additionally available - offers various options for more detailed evaluation of the temperature values
ComSoft CFR 21 Part 11 software - also available - ideal for the special requirements of CFR 21 Part 11 in the pharmaceutical sector
To program the data logger, you need a USB cable, which is not included in the scope of delivery. Data can also be transferred to the PC via the USB cable or via an SD card. Both can be ordered as optional accessories.
