The Industrial Dual Function Voltage Detection Screwdriver should be positioned as a two-level service tool series, not as another single voltage tester screwdriver. Its main value is the 998S and 998 model combination. The 998S version uses a Φ4×100mm bit for compact service work, while the 998 version uses a Φ6×142mm bit for stronger handling and longer reach.
Both models support 80V–500V AC contact voltage indication and use a built-in neon lamp. The tool combines voltage checking with slotted and Phillips screw operation, making it suitable for users who need one tool for basic circuit indication and light screw work around switches, sockets, appliance covers, terminal points, and service panels.
The PP + TPR engineering plastic handle gives this product a more industrial hand-tool identity than slim transparent voltage pens. The transparent handle section supports indicator viewing, while the TPR grip area improves holding control during installation and maintenance work.
This page should focus on industrial two-model selection. It should not repeat the NS-01L page, which is built around one 208mm ergonomic dual-function screwdriver. It should also stay different from the removable double-end model, which focuses on removable bit flexibility. This page belongs to a stronger industrial service category with compact and heavy-duty choices.
Model 998S uses a Φ4×100mm bit for compact repair kits and portable service use.
Model 998 uses a Φ6×142mm bit for buyers who need a stronger and longer service option.
Two model choices help distributors cover different user levels within one product series.
Slotted and Phillips dual-function design reduces tool switching during basic service work.
PP + TPR handle gives better grip identity than simple transparent tester handles.
40Cr steel blade supports contact testing and light screw operation.
Nickel-plated shaft option improves product appearance for retail and OEM supply.
The series is suitable for industrial maintenance packs, electrician kits, and hardware distribution.
Model | Bit Specification | Best Positioning |
|---|---|---|
998S | Φ4×100mm | Compact service kits, household repair packs, portable electrical tool sets |
998 | Φ6×142mm | Heavier maintenance work, longer access, industrial service channels |
Buyer Scenario | Why This Series Fits |
Industrial maintenance supply | 998 and 998S cover different service levels |
Electrician tool kit | Voltage checking and screw operation are combined in one tool |
Appliance repair channel | 40Cr dual-end blade supports common service points |
Hardware retail upgrade | PP + TPR handle and nickel-plated shaft option improve product value |
OEM electrical tool line | Model, shaft finish, color, logo, barcode, and packaging can be customized |
This product should be clearly separated from other dual-function voltage tester pages.
Compared with Dual Function Ergonomic Voltage Tester Screwdriver NS-01L, this page should not focus on one fixed 208mm model. NS-01L is a single ergonomic service screwdriver. This product is a two-model industrial series with 998S and 998 options.
Compared with Removable Double End Voltage Tester Screwdriver, this product should not focus on removable bit design. The removable model is compact and flexible. This model focuses on fixed dual-function structure, two bit specifications, and industrial maintenance positioning.
Compared with Dual Size Insulated Voltage Test Screwdriver Model 218 / 219, this product does not only offer two lengths. It offers two different bit specifications and slotted plus Phillips screwdriver function, which gives it a stronger service-tool role.
Compared with standard transparent testers, this product is positioned at a higher value level because it combines voltage indication, screwdriver operation, PP + TPR handle, 40Cr steel blade, and optional nickel-plated shaft.
