NI 405 plus, multimeter with insulation measurement

626005050
Summary

Waterproof CAT IV multimeter with insulation measurement


The sturdy and waterproof (IP67) NI 405PLUS is a True
RMS multimeter with built-in insulation resistance tester.
Insulation resistance measurement can be measured
with 4 different test voltages and can go up to 4 GΩ.
 
The NI 405PLUS includes useful extras such as duty cycle
measurements and milliamp 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 it easy to
perform required safety checks.
