A self contained testing device ( 100 ) for assaying precious metals includes a housing ( 110 ) for various mechanical and electronics components integrated to form a compact testing device. The testing device ( 100 ) includes a gel dispenser, e.g. syringe ( 200 ), an anode probe ( 650 ) to which may be attached a specimen holder ( 653 ) or crocodile clip ( 907 ), a cathode probe ( 624 ), and an electronic circuit ( 691 ) connected to the anode and cathode probes for conducting and recording tests. A sample ( 686 ) is held in the sample holder ( 653 ), e.g. by a spring clip ( 667 ), and gel is dispensed through a nozzle ( 115 ) to connect the specimen and cathode probe. The characteristics of the resulting cell are analysed and the results provided on a display ( 612 ).
