ETCR3400C Insulation Resistance Tester-Earth Resistance/Insulation Resistance Tester-ETCR

ETCR3400C Insulation Resistance Tester

Product Main Function

1. Insulation Resistance Measurement, Range: 1MΩ~200GΩ

2. AC Voltage Measurement, Range:1~750V

3. Test Voltage Range: 5000V



ETCR3400C  series Insulation Resistance Tester is a high performance handheld digital instrument. Suitable for measuring the insulation resistance of electrical machines, cables, switches, electrical appliances and other electrical equipment and insulating materials, and can be used for maintenance, testing and verification of various electrical equipment. It is a common and essential instrument for telecommunication, electric power, meteorology, machine room, oil field, electromechanical installation and maintenance, and industrial enterprise sectors that use electric power as industrial power or energy.

Improved circuit and new safety structure design, more complete functions, higher accuracy, more convenient and reliable operation, equipped with shock-proof sleeve and dust proof, moisture-proof structure, can adapt to the outdoor working environment. During measuring, the testing voltage according to the different models output are available from 100 v / 250 v / 500 v / 1000 v / 2500 v / 5000 v gears to selection. Measuring insulation resistance range max up to 200 gΩ, and has the function of the AC voltage measurement.
