The Testo 0516 0270 Heating Smart Case for Probes protects instruments and keeps them tidy. The case's soft foam insert with custom-fit compartments ensures that each measuring instrument has its own space. And because of its impact-resistant and flexible hard outer shell, tools will be unharmed if the case falls on the floor. The Smart Case is suitable for the safe storage and easy transportation of Smart Probes 115i, 510i, 805i, 410i and 549i (sold separately).
