Voltage tester EMOS 5301284 screwdriver type 0–250 V with light and sound indicator

Voltage tester EMOS 5301284 is a screwdriver-type non-contact tester designed to detect AC voltage from 70 to 250 V and DC voltage from 0 to 250 V. The compact probe and insulated handle allow quick checks of sockets, switches and wiring; the device also determines polarity and includes power supplied by two LR44 batteries (included).

Advantages

The tester provides both optical and acoustic indication for reliable detection of live conductors. Its slim screwdriver form factor enables access to tight terminals and outlets. Non-contact sensing increases user safety during voltage checks, while battery operation makes the tester ready to use immediately.

Suitable for

• Quick verification of wall sockets and plugs
• Checking switches and lighting circuits
• Basic polarity and short-circuit identification
• DIY electrical troubleshooting and professional preliminary checks

Key specifications

• AC voltage detection (non-contact): 70–250 V
• DC voltage detection (non-contact): 0–250 V
• Polarity detection
• Optical and acoustic indicators
• Batteries: 2 × LR44 (included)
• Frequency range: 0–60 Hz

How to use

Hold the insulated handle and bring the tester tip close to the conductor, socket or terminal to be checked. Observe the light indicator and listen for the acoustic signal to determine presence of voltage; use the polarity function when required. Replace batteries with two LR44 cells when indicator brightness or sound weakens. Follow standard electrical safety precautions and disconnect power when performing repairs.

Usage recommendations

Use the tester for preliminary voltage checks only; it is intended for detection and indication, not for precision measurement. Do not rely on the device for insulation testing or detailed diagnostics; always follow safety procedures and use appropriate measuring instruments for in-depth testing.
