Pressure calibrator designed for use in potentially explosive areas. 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 Pressure sensor input of 20 bars full scale with 0.05% accuracy. Built-in pressure / vacuum hand pump; with vernier and bleed valve. Measures pressure up to 200 bar (using one of the eight intrinsically safe Fluke 700PEx pressure modules). True RMS current and voltage measurements gives you accurate readings of non-sinusoidal waveforms
