DC, sampled DC, pulse and differential pulse polarography
Manufacturer: Entek Elektronik, İvedik OSB, Ankara · Designed and manufactured in TürkiyeA polarographic analyzer manufactured by Entek Elektronik; a microprocessor-controlled system for trace element and organic compound analysis with DC, sampled DC, pulse and differential pulse techniques. With a current range from 0.02 µA to 10 mA, an electrometer input impedance above 10¹¹ Ω and a ±100 V / 20 mA potentiostat output, it is used together with the CGME mercury electrode and the C-4 cell stand.
