INSULATION TESTER
IR4057-50
Quick Response Comparator Offering Reading Stability in High-speed Digital Format
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, 50V to 1000V digital insulation resistance tester with bargraph, and delivers efficient functions and features to help shorten work time associated with field insulation testing. CAT III 600 V Key Features • Wireless support. Transfers measurements to your smartphone or tablet and allows you to quickly create reports with field photos and drawings. (Optional Wireless Adapter Z3210 is necessary) • Wirelessly transfer measurement data to Excel forms for input (Will be supported by the 2021 upgrade) • 5-range testing voltage of 50 V/100 MΩ to 1000 V/4000 MΩ • Digital bar graph • Stable & high-speed digital readings, 0.3 second response time for PASS/ FAIL decisions • Drop proof onto concrete from 1m (3.28 feet) • Bright LED, luminous LCD, test lead with bright LED lamp to illuminate near hand (Option L9788-11 or L9788-10) • Continuity check via 200 mA testing • Built in AC/DC voltage meter, useful for testing solar power generation systems and electric vehicles

Compatible with Wireless Adapter Z3210 (optional). It transfers measurements to your smartphone or tablet and allows you to quickly create reports with field photos and drawings.
GENNECT Cross, a free app designed specifically for use with Hioki measuring instruments, lets you check and manage measurement results and create reports. The software provides a range of functionality that helps manage data in the field, including photographing measurement sites, placing measurement results on photographs, and saving hand written memos. *Optional Wireless Adapter Z3210 is necessary.
Compare measured values to pre-set reference values to generate a pass or fail judgment with the Comparator function. (also pair with insulation resistance measurement and low-resistance measurement) 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 (option), letting you check for insulation integrity without needing to look at the instrument.
