Dixon A240 Series Ground Verification Monitor

Dixon's A240 series ground verification monitors are designed to mitigate the danger of static buildup by verifying the presence of a high quality and reliable earthground bond. With the presence of a ground path for static to dissipate, loading and unloading of flammable or combustible liquids can be done safely. The A240 monitor verifies the bond is of sufficient quality to prevent static buildup. Internal indicators inform the operator whether the process connection is safely grounded and internal relay contacts may be used to interlock operations until a safe earth bonding has been established.
