INSULATION TESTER
Hioki iR4057-50
High-Speed Insulation Resistance Tester
Hioki insulation testers or megohmmeters feature all-in-one designs including built-in rugged cases and test lead storage compartments. The IR4057-50 is a 5-range, 50 V to 1000 V digital insulation resistance tester with bargraph and delivers efficient functions and features to help shorten work time associated with field insulation testing.
Comparator Function Provides PASS/FAIL Decisions at a Glance
Compare measured values to pre-set reference values to generate a pass or fail judgment with the Comparator function.
The insulation testers give you pass/ fail results using a beeping sound, LCD light, and indication right on the test lead with remote control switch*, letting you check for insulation integrity without needing to look at the instrument.
* Image shows L9788 probe. Sold separately.
White LED Lighting That's Easy to Read in Dim Locations 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.
Easy-to-Use Measurement Switch
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.
* Image shows model IR4016. IR4057 is a digital meter.
Wireless Support: Wireless communication capability for even greater convenience (Z3210 Wireless Adapter sold separately)
