Oil drilling platforms or platforms for gas extraction, pipelines, refineries, chemical plants: in these contexts, where there’s no margin of error, it is essential that the tools used by the operators comply with all the Health and Safety regulations. Precisely for these specific contexts RealWear has designed the HMT-1Z1, monocular Smart Glasses compliant with the safety protocols and standards of potentially explosive areas (ATEX Zone 1, IECEx Zone 1 and CSA C1-D1) and requiring certified equipment. Video calls with remote technicians, visualization of contents in Augmented Reality, navigation between work documents, workflow verification, access to data and information: all the features of this device can be activated via voice control, so as the operator has complete freedom of movement and hands-free work. The RealWear HMT-1Z1 can also be combined with hard hats, ear muffs and safety goggles, and are extremely rugged: they are resistant to 2-meter drops and have an IP66 protection level, which makes them impermeable to water and dust.
