ATEX II 1G EEx ia IIC T4 Compliant. Multimeter functions include AC/DC voltage, resistance, capacitance, frequency, diode and continuity Peak hold captures inrush currents and transients Data hold and Max/Min functions Built-in pressure / vacuum hand pump; with fine adjust vernier and bleed valve. Pressure measurement to 0.05% of full span; using an internal pressure sensor. Pressure measurement to 200 bar using any of eight intrinsically safe Fluke 700PEx Pressure Modules. True RMS current and voltage measurements gives you accurate readings of non-sinusoidal waveforms
