TD1210 Verification Device for Leakage Current Tester

Safety Instrument Detection

The TD1210 integrates a DC~1MHz wideband constant current standard source, constant voltage standard source, DC ohmmeter, impedance tester, AC voltage standard meter, and other functions. It is applied for calibrating conventional leakage current meters, contact current testers, and medical leakage current testers, providing high accuracy and wide frequency coverage.
