Socket & See VIP ESI 2-Pole Tester - Interchangeable test prods
- Two pole voltage indicator with automatic impedance detection.
- Interchangeable straight and right-angled GS38 compliant test prods add further practical applications to the tester.
The Socket & See VIP ESI 2-Pole Tester is a professional two pole voltage indicator developed with input and field trials from UK SMART metering and utility companies. Designed for electrical and metering applications, it combines AC/DC voltage indication with a useful high/low circuit impedance check and automatic handling of ghost or induced voltage.
The Socket & See VIP ESI operates across 50–600V AC/DC, with clear LED indication at 50V, 110V, 230V and 400V. Its dual colour-coded display provides both voltage and impedance information, helping the user quickly assess the circuit being tested.
Unlike many two pole testers that require buttons to be pressed to apply a load when checking ghost voltage, the Socket and See VIP ESI performs this function automatically, with no buttons required. It is also battery-free, keeping operation simple and reducing reliance on battery condition.

Why Choose the Socket & See VIP ESI 2-Pole Tester?
The Socket & See 2-Pole Tester offers more than basic voltage indication by incorporating a physical circuit impedance check.
When an impedance of less than 100Ω is detected, the red LoZ LED illuminates, indicating that further investigation is required before proceeding. A high impedance above 100Ω is indicated by the green HiZ LED.
The VIP ESI also simplifies checks for ghost or induced voltage. Rather than requiring the user to press load buttons on the tester and probe, the instrument performs this automatically. This button-free operation, together with its battery-free design, helps make the Socket and See 2-Pole Tester straightforward to use in the field.
For professionals looking for a versatile Socket and See VIP ESI 2-Pole Tester, the combination of voltage indication, impedance detection, GS38 compliant prods and robust construction makes it particularly suited to electrical and utility testing applications.
