The integral pneumatic calibration hand-pump of the 718-Ex intrinsically safe portable pressure calibrator contains protective check valves to prevent fluid contaminants being pulled back inside the pump assembly. The check valves are also easily servicable via direct access on the underside of the calibrator. A volume adjuster is located alongside the coarse hand pump for fine adjustment of calibration setpoints.

The 718Ex intrinsically safe portable pressure calibrator includes a current meter for checking the output of pressure transmitters and a switch test mode with capturing the point which a pressure switch opens and closes. A hold button is provided for freezing the measurements so that they can be recorded.

The accessories included with the 718Ex intrinsically safe portable pressure calibrator are banana plug test leads with crocodile clips, protective red rubber holster, two 9 volt batteries, in-line filter and user manual on CD Rom.
