Multifunction Tester for Electrical Installations

The compact multifunction tester that does more.

Forget bulky installation testers. The FASTCHECK4010G delivers professional-grade electrical safety testing — advanced RCD testing (including 1 A and ramp), loop and line impedance, True RMS voltage, harmonics and socket checks — in a compact format that goes wherever you go.

Compliant with IEC 61557-3 and IEC 61557-6, it works on single-phase and bi-phase systems as standard, and three-phase systems with the included accessory. Save results and generate professional reports instantly by scanning the QR code with the free KPS FASTCHECK app.

More capability. Same compact size.
Built for real-world installation work.
