The Fluke 718EX is an intrinsically safe pressure calibrator engineered for demanding applications in hazardous areas. Certified to ATEX II 1G EEx ia IIC T4, this rugged instrument ensures safety and reliability when calibrating pressure and current in explosive environments. With a built-in pressure/vacuum pump, fine adjust vernier, and bleed valve, the 718EX provides precise pressure generation and measurement up to 300 psi (20 bar) with an accuracy of 0.05% of full span. For higher pressures, it supports external Fluke 700PEx Pressure Modules up to 200 bar. The device also measures current with 0.02% accuracy and 0.001 mA resolution, and includes a pressure switch test function for comprehensive calibration tasks.
