Construction The Models 3711 and 3731 bodies are built of Lexan® (or equivalent polycarbonate) for rugged use. The probe heads are encapsulated in a double-walled shell for extra strength and reinforced for enhanced field reliability. Overall construction and mechanical design ratings such as drop test, shock, vibration and weatherproofing against water penetration or dust, meet or exceed IEC standards. These products have also been designed to EN 61010, Cat. III and are UL approved and are CE Marked. The probe head, (jaw) is a key component in the measurement and overall product performance....
