With a diameter of 55 millimeters the EC-710-090 Ex surveillance camera is the world's smallest explosion-proof camera. The optical system is protected by a chemically hardened lens. Even with the stainless steel housing it weighs no more than 436 grams and still resists ambient aggressive chemical substances as well as substantial mechanical stress, including vibrations. Moreover, the EC-710-90 Ex can withstand extreme temperatures, making it suitable for universal application in installations world-wide. The camera will work reliably in arctic conditions of down to - 30 °C as well as at desert temperatures of up to +75 °C. The camera's 1/3"-CCD sensor produces a PAL or CVBS image of either 470 or 580 TV lines. The fixed camera viewing angle is +/- 90° horizontally and 68° vertically.
