These instruments feature a robust design that can withstand being dropped onto concrete from a height of 1 m. Difficult to damage, this insulation tester is ideal for use in the field.
The scale is lit by a white LED, ensuring that insulation resistance values are easy to read, even when using the instrument in a dim location.
You can keep track of remaining battery life since it’s shown on the LED, eliminating the need to worry about sudden loss of battery power in the field.
The instrument’s measurement switch can be operated with just the thumb. Press for a single measurement or lift up for continuous measurement of insulation resistance.
By using switch-equipped measurement leads, you can start and stop insulation resistance measurement remotely. There’s also a handy light for improved convenience when working in dim locations.
