Global Tech Innovations offer a range of installation testers designed to support various electrical testing applications, from basic verification to advanced diagnostics. Our product range includes multifunction testers that combine several testing functions such as insulation resistance, continuity, loop impedance, and RCD testing into a single device for comprehensive system analysis. We also provide specialized insulation testers to measure insulation resistance and identify potential faults, loop impedance testers to assess the effectiveness of protective devices, and dedicated RCD testers to verify the proper operation of residual current devices. Additionally, continuity testers are available for confirming conductor connections, and phase sequence testers help ensure correct phase sequencing in three-phase electrical systems, preventing equipment damage and ensuring safety.
