GW Instek has introduced their GOM-804 as the latest installment to their new series of DC milliohm meters. The GOM-804 offers a vast 3.5” TFT color display with 50,000 counts maximum measurement display for superior measurement clarity. It is suited with a 60 readings per second fast sampling rate, 0.05% precision and a four-wire measurement method in addition to the temperature measurement and temperature compensation measurement function.
The meter delivers a D-sub 25-pin combined interface to carry out, contingent on the functionalities, Handler, Scan or EXT IO for respectively connecting to a sorting machine; connecting to an external on-off switch, and directly conducting external trigger control. Its functionality keys and direction keys allow for ease of operation, enabling users to complete their tasks with efficiency and convenience.
