CEM DT-9330 Electrical Tester

The CEM DT-9330 is a highly reliable electrical tester that conforms to the rigorous standards set by EN 61243-3:2014, ensuring its suitability for professional use in various electrical testing scenarios. This device offers an expansive LED indication range from 12V up to 600V for both AC and DC measurements, making it extremely versatile for a wide range of voltage testing requirements.

One of the standout features of the DT-9330 is its independent Extra Voltage Indicator (EIV) LED. This unique feature provides an additional safety measure, indicating the presence of more than 50V AC or 120V DC even if there is no battery power or if the main circuit fails. This ensures consistent safety checks in environments where power inconsistencies are common.

The tester is designed for rugged use with a double-insulated wire that enhances its durability and user safety in demanding environments. Additionally, it incorporates a fixed impedance of 200 kΩ, allowing a minimal current flow of up to 3.5 mA at 1000V, which helps in reducing the risk of circuit damage during testing.
