Testo 175 and 176 series data loggers from Testo are designed for recording environmental parameters (temperature, humidity and pressure). They feature a USB port (for data transfer to a PC) and an SD memory card with a storage capacity of 1 million values (175 series) or 2 million values (176 series).
The dimensions of the 175 series are 8.9 x 5.3 x 2.7 cm (without probes), while those of the 176 series are 10.3 x 6.3 x 3.3 cm. The 176 series is particularly suited to demanding environments (laboratories, clean rooms, etc.).
Each range includes several models (4 in the 175 series, 6 in the 176 series) so that everyone can find the model best suited to their needs. Depending on the model, the transducers are either indoor or outdoor, and in the case of outdoor transducers, they can be fixed or removable. Models in the 175 series offer 2 measurement channels, while those in the 176 series have up to 6. The testo 176 P1 stands out from the rest, measuring and documenting not only temperature and humidity, but also absolute pressure.
