The flush type test facility
                                        is designed for flush mounted, at-grade terminal that is used for conveniently
                                        monitoring electrical currents and potentials associated with all type of
                                        underground piping cables and other metallic structures.
                                        
The test facility is made in
                                        cast iron; therefore it will maintain its structural integrity during hard
                                        usage and is suitable for installation in asphalt. The flush type is used as a
                                        terminal for test leads to read:
                                        
                                    Underground structure-to-soil potential
                                    
                                    Cathodic protection anode current
                                    
                                    The resistive intergrity of insulation flanges and joints
                                    
                                    The integrity of insulation between all types of underground metallic structures,
                                    such as between a carrier and its casing
                                    
                                    Stray currents on all types of underground structures
                                    
                                
                                        
The test facility cover can be
                                        lockable or normal type. The normal type is easier for maintenance and
                                        monitoring works; while the lockable type is more suitable to prevent vandalism.
