Testo's testo 175 and 176 recorders are designed to record environmental parameters (temperature, humidity and pressure). They have a USB port (for data transfers to a PC) and an SD memory card with a storage capacity of 1 million values (series 175) or 2 million values (series 176).
The dimensions of the 175 series are 8.9 x 5.3 x 2.7 cm (without the probes) while those in the 176 series are 10.3 x 6.3 x 3.3 cm. The 176 series is especially aimed at demanding environments (laboratories, clean rooms,...).
Each range includes several models (4 in the 175 series, 6 in the 176 series) so that everyone finds the model best suited to their needs. Depending on the model, the sensors are indoors or outdoors, and in case they are outside, they can be fixed or removable. The 175-series models offer 2 measuring lanes, while the 176-series models have up to 6. In all this offer, we can distinguish in particular the testo 176 P1, which allows not only to measure and document temperature and humidity, but also absolute pressure.
