Dual-Function Test Pen with Crystal Handle

Product Overview

The Dual-Function Test Pen with Crystal Handle is a basic electrical testing tool designed for compatible AC voltage detection and routine maintenance support tasks. It features a double-ended blade construction with a built-in neon bulb and electronic resistor for AC voltage testing in the 100–500V AC range.

The blade is made from chrome-vanadium steel for strength and durability. The ABS plastic handle is designed for comfortable handling, convenient operation, and dependable service life. Its crystal-style transparent handle helps users observe the internal neon indicator during testing.

The product is suitable for household circuit checking, outlet and switch testing, low-voltage electrical installation, equipment maintenance, and general electrician repair work. Before use, please confirm line voltage, product compatibility, and applicable local electrical safety requirements.

Safety Notice: A test pen is generally used as an auxiliary tool to indicate the possible presence of AC voltage. It should not be used as the only method to verify that a circuit is de-energized. For professional work, industrial distribution systems, or safety-critical applications, use a properly rated multimeter, two-pole voltage tester, or other professional test equipment for confirmation.

Use and Maintenance Tips

Inspect the handle, blade, and internal indicator components before use.

Confirm that the circuit voltage is within the compatible 100–500V AC range.

Before testing, it is recommended to verify functionality on a known energized compatible circuit.

Follow the product instructions and applicable local electrical safety procedures during use.

Keep hands, the handle, and the working environment dry.

Do not use the product in rain, wet areas, flammable gas environments, or locations with explosion risks.

Do not disassemble, modify, or repair the internal electronic components by yourself.

Clean the blade and handle after use, then store the tool in a dry, clean location out of reach of children.

Stop using the product if the neon bulb does not illuminate, indication is abnormal, the handle is cracked, the blade is bent, or other defects are found.

For de-energization verification, industrial electrical maintenance, or high-risk work, use properly rated professional testing equipment for secondary confirmation.

FAQ

1. What is the voltage testing range of this test pen?

This product is designed for compatible AC circuit testing within the 100–500V AC range. Before use, confirm that the circuit voltage is within this range and follow the product instructions and local safety requirements.

2. Can this test pen measure an exact voltage value?

It should not be used as a precision voltage measurement instrument. This product is mainly intended for AC voltage indication and basic circuit testing. For accurate voltage readings, use a properly calibrated digital multimeter or another professional instrument suitable for the application.

3. Can it be used to test DC voltage?

The marked testing range is 100–500V AC. Do not use the product for DC voltage testing unless the actual product or packaging clearly states that DC testing is supported.

4. Can this test pen confirm that a circuit is fully de-energized?

Do not rely on a test pen alone to confirm that a circuit is fully de-energized. A test pen can provide an indication of possible AC voltage presence, but professional work, installation, repair, or high-risk tasks should be verified using a properly rated two-pole voltage tester, multimeter, or other professional equipment.

5. Do you offer OEM/ODM customization?

Yes. OEM/ODM services are available for blade logos, handle colors, labels, hang cards, color boxes, manuals, barcodes, and packaging. Please provide your estimated order quantity, target market, technical requirements, and customization needs for evaluation.
