NI 407 plus, multimeter with insulation measurement
626005059Summary
Waterproof CAT IV multimeter with insulation measurement
The sturdy and waterproof (IP67) NI 407PLUS is a True RMS multimeter with built-in insulation resistance and earth bound tester. Allows the insulation resistance to be measured with 5 different test voltages for measuring up to 5 GΩ. The meter can measure the earth bound with 200 mA according the applicable EN 61557-4 standard
The NI 405PLUS includes useful extras such as duty cycle measurements andmilliamp readings for analogue 4-20 mA current loops in industrial process monitoring.
The temperature measurement, a clear display with backlight and memory,make this meter perfectly useful for installation engineers. The meter makes iteasy to perform required safety checks.
