testo 175 T1 – data logger for temperature

The testo 175 T1 data logger is particularly suitable for professionals who require long-term and precise temperature monitoring in storage and cold storage rooms. This allows users to ensure compliance with relevant norms and standards, for example in the food or pharmaceutical industries. The [testo 175 T2] offers similarly precise measurement functions, which also impresses with a robust housing and HACCP conformity, making it an additional option for a wide range of applications.

Measurement functions and performance features

This data logger relies on modern sensor technology (NTC), which allows measurements in the range from -35 °C to +55 °C. Thanks to an accuracy of ±0.5 °C in the relevant temperature window, fluctuations in the cold store, freezer area or transport vehicle can be detected quickly. A major advantage is the large memory capacity of up to one million measured values. This means that sufficient capacity is available even with increased measurement frequency or particularly long documentation periods.

The battery-operated device (3 x AlMn type AAA) has a service life of up to three years and can withstand even intensive use. The IP65 protection class ensures high resistance to moisture and dirt. The robust plastic construction (dimensions: 89 x 53 x 27 mm; weight: 130 g) proves to be very resistant in demanding environments. Professionals also benefit from the following features:

– Temperature measuring range from -35 °C to +55 °C
– Internal memory for 1,000,000 measured values
– Mini-USB and SD card slot for data transfer
– Measuring cycle variably adjustable (10 s to 24 h)
– Battery change without data loss
– Indication of limit value violations directly on the display

The integrated alarm function is a special feature: As soon as set threshold values are exceeded, this is displayed immediately. In addition, the measurement curves and limit value violations can be read off the display at any time, which enables quick reactions. The software features also cover different needs. The free ComSoft Basic version offers simple programming and evaluation, while the paid versions ComSoft Professional or ComSoft CFR 21 Part 11 are available for detailed analyses or pharmaceutical requirements.

Certifications and standards

Strict guidelines are often applied in the food and pharmaceutical sectors in particular. This model complies with important standards such as EN 12830 and the requirements of EU Directives 2014/30/EU and 2011/65/EU. The appliance is also HACCP-compliant and certified by HACCP International. It therefore supports the highest level of quality assurance, particularly for temperature-sensitive products in refrigeration and storage processes.

Concrete application examples

– Monitoring refrigerated warehouses: Thanks to its large memory and long battery life, the device can continuously record the temperature in large refrigerated warehouses over several months
– Documentation of transportation conditions: In the field of logistics for goods subject to cold chain requirements, such as dairy products or frozen goods, it is possible to check whether the specifications have been adhered to over the entire transportation route.
– Control of pharmaceutical products: Safe compliance with standards (e.g. CFR 21 Part 11) enables use in the pharmaceutical sector, for example for vaccines or sensitive active ingredients.
– Use in freezers and deep freezers: The robust design and IP65 protection class allow the device to remain in the cooling environment permanently and simplify cleaning and maintenance.

FAQs

How is the device read out?

The measurement data can be transferred to the PC either via SD card or mini-USB cable. Alternatively, the values can be viewed directly on the display.

Which software can be used?

There are three versions available with different functionalities: ComSoft Basic (free of charge), ComSoft Professional and ComSoft CFR 21 Part 11. The latter is particularly suitable for standardized environments in the pharmaceutical industry.

Is calibration necessary

It is generally advisable to calibrate the device at regular intervals to ensure long-term measurement accuracy. A calibration protocol is often already included.

What happens when the batteries run out?

The logger data is backed up automatically. The batteries can be changed quickly and without losing any data.

Can the housing be cleaned?

Thanks to the IP65 protection class, the device is water and dust resistant. The plastic surface can be treated carefully with a damp cloth and mild detergent.

Conclusion

This model enables precise temperature recording for laboratories, pharmaceutical companies and food production and logistics. The large data memory, robust design and long battery life make it easy to use in continuous operation. Optionally available software variants also enable individual evaluation of the measured values. Compliance with important standards (e.g. EN 12830 and HACCP) proves the device’s suitability for demanding applications and makes it a reliable all-rounder for temperature monitoring.
