Product Details

KletsKEW3125A Digital High Voltage Insulation Resistance Meter (5000V)

KletsKEW3125A Digital High Voltage Insulation Resistance MeterisHigh voltage insulation resistance meter with 5 ranges (3125A) and 4 ranges (3025A) for measuring insulation resistance.
Design in compliance with international safety standards:
IEC 61010-1, -2-030 (CAT III 600V/CAT IV 300V Pollution Level 2)
IEC 61010-031 (Requirements for Handheld Probes)
● Automatic discharge function: When testing the insulation resistance of capacitive loads, the charging charge is automatically released after measurement. The discharge state can be confirmed in voltage mode.
The backlight function is convenient for working in low light or at night.
A bar chart displays the measurement results.
● Warning signs and buzzing warnings for live lines.
● Automatic shutdown function: To avoid battery waste caused by forgetting to shut down, the instrument will automatically shut down when there is no operation for 10 minutes after measurement.
● Automatic measurement and PI measurement (polarization index measurement), DAR measurement (induced absorption ratio measurement).
