Entel
HT800 series UL Intrinsically Safe

The unique and advanced HT800 Series conforms to all aspects of U.L. certification for portables used in hazardous locations. It further exceeds this by being fully submersible - all other products in this class are merely splash-proof construction. Entel believes that non-submersible portables have no place in the harsh world of maritime and terrestrial high-risk environments. Supplied with a 3 year warranty.
