VOLTCRAFT FIT-100 Installation Tester VC-12321015 Multifunction Electrical Safety Tester

With insulation test voltages up to 1000 V and a measurement range reaching 2000 MΩ, the VOLTCRAFT FIT-100 Installation Tester delivers professional-grade electrical safety verification in a rugged, IP65-rated housing. This comprehensive instrument combines insulation resistance, loop impedance, RCD testing, voltage, frequency, continuity, and phase sequence checks in one device, making it an indispensable tool for electricians and maintenance technicians.

Overview

The FIT-100 is engineered for daily use in demanding environments. Its large backlit LCD ensures clear readings even in poorly lit installation areas, while the internal memory stores up to 1000 measurement values for later analysis via USB. Powered by eight AA batteries, it offers cordless convenience without compromising on performance. The automatic test sequences for RCD, loop, and insulation measurements streamline workflows and reduce the risk of operator error.

What stands out

• Wide insulation test voltage range: 50 V, 100 V, 250 V, 500 V, 1000 V
• RCD testing with ramp test and currents from 10 mA to 1000 mA for Type A and AC
• Loop impedance measurement from 0.01 Ω to 2000 Ω with prospective short-circuit current up to 20 kA
