Habotest HT5910 Digital RCD / Loop Resistance Tester

The Habotest HT5910 is a professional digital RCD and loop resistance tester designed for electricians and maintenance professionals. It measures loop resistance (0.1–2000Ω), contact voltage, alternating voltage (0–440V), frequency, and RCD tripping time and current. The device supports multiple current levels (10–500 mA) and phase angles (0°/180°).

• Loop resistance measurement from 0.1 to 2000Ω with ±10% accuracy
• RCD testing for tripping time and current (0.2–1.1 IΔN)
• Contact voltage range 0–99.9V
• Alternating voltage up to 440V
• Frequency measurement DC and 45–65 Hz
• Data storage for 100 measurement groups
• USB 2.0 interface for data transfer
• Safety rated EN61010-1 CAT III 600V

Powered by 6 AA batteries (not included), the HT5910 features a clear LCD display and a rotary knob for easy mode selection. Ideal for testing RCDs, loop impedance, and voltage in residential and commercial installations.
