EK-C349B High Voltage Insulation Meter

EK Instruments EK-C349B is a professional high voltage insulation meter. Designed for industrial electrical measurement and field testing. Built with precision engineering and reliable components for long-term stability.

Product Function

Suitable for measuring the resistance value of various insulating materials and the insulation resistance of transformers, motors, cables and electrical equipment.
Insulation Resistance test (IR); Polarization Index test (PI); Dielectric Absorption Ratio test (DAR); AC/DC Voltage test (V).

Product Features

1.Insulation resistance value, test time, and output voltage are displayed on the same screen. Test operation and historical record inquiry are very convenient.
2.Exclusive strong anti-interference technology ensures stable testing capability in scenarios with large distributed capacitance (such as long cables) and in strong electromagnetic interference environments (such as substations).
3.Comprehensive measurement indicators: Insulation Resistance (IR), Polarization Index (PI), Dielectric Absorption Ratio (DAR), AC/DC Voltage (V).
4.Automatic discharge function: After testing, the charged charge of the tested object is released automatically and rapidly, without the need for an external discharge circuit.
5.Large-capacity test record storage: Test records can be browsed and analyzed directly on the instrument. Can automatically store up to 600 sets of real-time test data with test timing.
6.USB communication upload function: Record data can be uploaded to a computer for data storage and statistical analysis.
7.Bluetooth communication function: Test results can be uploaded to a mobile phone.
