Product Overview

The Removable Double End Voltage Tester Screwdriver should be positioned as a compact service tool with a replaceable-use structure, not as another ordinary soft grip voltage detector. Its main difference is the removable double-end bit. This gives the product a more flexible role than fixed-probe testers, especially for buyers building electrical service kits or light repair assortments.

The tool supports 80V–500V AC contact voltage indication through a built-in neon lamp. It is designed for quick live circuit checking before simple adjustment work around socket covers, switch panels, plug points, and appliance housings. The 40Cr steel bit supports contact testing and light screw handling in one compact structure.

The 155mm body length keeps the product shorter than long dual-function tester screwdrivers, while the 25mm PP + TPR handle gives a more comfortable grip than slim transparent tester pens. The 110mm bit length and 77mm exposed bit length provide practical reach without making the tool too large for retail kits or service pouches.

For product line planning, this page should focus on removable double-end flexibility. It should not repeat the NS-01L dual-function page, which focuses on a longer 208mm screwdriver body and Phillips plus slotted service use. This model is shorter, more compact, and better positioned as a flexible removable-bit tester for maintenance packs.

Removable Bit Value

  • Removable double-end bit design gives the tool more flexibility than fixed-probe voltage testers.

  • 155mm body length keeps the tester compact for service pouches, repair kits, and retail packs.

  • 110mm bit length provides useful access for socket covers, switch panels, and appliance housings.

  • 77mm exposed bit length supports contact work without turning the product into a long cabinet tester.

  • PP + TPR soft grip handle improves holding control during checking and light adjustment.

  • 25mm handle width gives a fuller grip than slim transparent electrical tester pens.

  • 40Cr steel bit supports basic screw contact and voltage testing work.

  • 40g weight gives the product a more solid hand feel than lightweight pocket testers.

Difference From Similar Models

This model should be separated from both soft grip testers and longer dual-function tester screwdrivers.

Compared with the Professional Soft Grip Voltage Detection Test Screwdriver, this model should not focus only on comfort. Both use PP + TPR handle material, but this product has a removable double-end bit structure, which is the main sales point.

Compared with Dual Function Ergonomic Voltage Tester Screwdriver NS-01L, this model is shorter and more compact. NS-01L has a 208mm overall length and should be written as a longer dual-function service screwdriver. This model has a 155mm body and should be written as a removable-bit compact maintenance tool.

Compared with pocket transparent testers, this product has a stronger service-tool structure. Compared with extended reach testers, it is not designed mainly for deep cabinets. Its role is flexible checking and light maintenance in a compact format.
