The digital probes: Hot Swap

Thanks to the easy Plug &Play principle, the digital probes can be simply exchanged during continuing operation in the case of a defect or necessary recalibration, without removing the whole data logger from the system – Hot Swap.
testo UltraRange: Data transfer over long distances

The new testo UltraRange radio technology was developed specially for in-house applications It is characterized by outstanding range and signal stability inside buildings. Thanks to the size of the individual packages, cached data are forwarded as quickly as possible, and connected components wirelessly updated, depending on the customer’s wishes.
