The U1450A and U1460A series insulation resistance testers are ideal for predictive and preventive maintenance measurements in electrical and industrial applications. With their vast measurement capabilities, efficient automated report generation, and high durability, you can accomplish more in a day’s work with the Keysight U1450A and U1460A series insulation resistance testers.

By adding a U1117A Bluetooth® adapter to these handhelds, you are able to perform tests remotely using a Windows PC or on iOS/ Android smart devices.

Test reports can also be generated automatically with the insulation resistance testers’ complimentary reporting software. These test reports can be generated in a tabulated or graphical form for easy interpretation and analysis.

All five models from these U1450A and U1460A series are certified to IP 67 and tested to withstand drops of up to three meters (10 feet), giving you full confidence to carry out tests even in harsh working conditions. You can also perform various measurements (e.g., measure voltage, current, continuity, capacitance, etc.) with the built-in digital multimeter. To test unique applications and sensitive device under tests (DUTs), the test voltages can be adjusted from 10 V to 1.1 kV in 1 V steps (on selected models).
