Two-pole voltage indicator Duspol expert 050262

Professional voltage and continuity tester – safety and functionality in one

Two-pole voltage indicator Duspol expert is a reliable tool designed for safe and precise measurement of AC/DC voltage in the range of 12 V to 1000 V. The tester combines the functions of a voltage indicator, circuit continuity test, and phase sequence detection, making it a versatile device for electricians, installers and service technicians. It will be useful both during installation and diagnostic work.

Functionality and advanced solutions

The Duspol expert tester offers a range of useful functions that facilitate work and increase safety:

• Optical signaling: Clear LEDs indicate voltage values (12 V, 24 V, 50 V, 120 V, 230 V, 400 V, 690 V and 1000 V AC/DC), eliminating the need to read from a display.
• Circuit continuity test: Quick identification of breaks in the circuit thanks to acoustic and optical signaling (up to 100 kΩ). A buzzer and a yellow LED indicate connection continuity.
• Phase sequence test: Allows correct recognition of the phase sequence, which is crucial when connecting three-phase devices. A green LED indicates the phase sequence.
• Phase presence test: A red LED indicates the presence of a phase in the tested circuit.
• Polarity test: Allows checking the correct polarity of DC connections.
• Non-contact voltage detection: Built-in phase detector allows safe detection of voltage without direct contact with the wires. A flashing yellow LED indicates the presence of voltage or a break in the cable.
• Vibration alarm: Additional warning of voltage presence via vibrations in the test handle – increases safety when working in difficult conditions.
• Measurement point illumination: Facilitates work in poorly lit areas.
• RCD tripping: Possibility of activating a residual current device (RCD) with a current of 30 mA – useful for checking the efficiency of protection.
• Two testing modes: Direct voltage display (high impedance test) and test with load (low impedance test) using buttons.

Construction and technical parameters

The Duspol expert indicator is made of durable materials, resistant to mechanical damage and external factors:

• IP65 protection class: Provides protection against dust and water jets – ideal for working in harsh environmental conditions.
• Solid housing with a rubberized grip surface: Provides comfortable use and a secure grip even with work gloves.
• Safety category CAT IV 600V / CAT III 1000V: Guarantees a high level of safety when working with electrical installations of various voltages.
• Battery-powered: Operates on two micro AAA batteries (1.5V) – displays voltage even with discharged batteries (from 50V).
• Complies with IEC/EN 61243-3:2015 standard: Confirms compliance with strict quality and safety standards.

The Duspol expert tester is an indispensable tool for every professional working with electricity, providing precise measurements, safe use and comfortable work.
