The Extended Reach Voltage Test Screwdriver is designed for contact points that are not easy to reach with compact voltage testers. This page should focus on access depth, not ordinary transparent-handle testing. Model 319 has a 185mm body, 19mm handle diameter, and Φ4×120mm probe, making it more suitable for recessed terminals, deeper wall boxes, and distribution panel checking.
The tester works within an 80V–500V AC range and uses a built-in neon lamp for live voltage indication. The transparent AS handle allows users to observe the neon response while keeping the product simple and familiar for electrical hand tool buyers.
The Φ4×120mm probe is the main reason this product should be listed separately from slim, pocket, and standard transparent testers. Pocket models are easier to carry, but they do not offer the same contact reach. Slim testers are lighter, but they are not built around deep terminal access.
This model is best positioned as the extended access version in the voltage tester category. It is suitable for buyers who need a longer probe tester for electrical boxes, cabinets, facility service packs, and maintenance tool assortments.
Φ4×120mm probe helps reach recessed terminals and deeper contact points.
185mm body length gives more working distance than compact pocket testers.
19mm handle diameter provides a fuller grip than slim transparent voltage pens.
4mm probe diameter gives a more solid contact structure for regular service use.
Built-in neon lamp supports quick live voltage indication during contact testing.
Transparent AS handle keeps the indicator visible without adding a digital screen.
Pocket clip supports storage in service bags or tool kits.
Model 319 fills the extended reach position between compact testers and heavier ergonomic models.
Scenario | Why Model 319 Fits |
|---|---|
Deep wall box check | Long Φ4×120mm probe reaches contact points inside deeper boxes |
Distribution panel inspection | 185mm body gives more access distance than compact testers |
Facility maintenance kit | 19mm handle supports steadier grip during routine service |
Equipment service pack | Extended probe helps check covered or recessed positions |
OEM electrical tool range | Model, logo, color, barcode, and packaging can be customized |
This model should not repeat the same content as standard transparent voltage tester pages. Its separate value is the long probe structure.
Compared with pocket testers, Model 319 is longer and more access-focused. Pocket testers are better for lightweight carry and small household packs. This model is better when the buyer wants a tester for deeper electrical points.
Compared with Model 999 professional transparent tester, this product has a wider 19mm handle and a longer Φ4×120mm probe. Model 999 can focus on balanced service size, while Model 319 should focus on extended access.
Compared with soft grip testers, this model does not focus on rubber comfort. Compared with dual-function testers, it does not need to focus on fastening use. Its main role is simple: reach deeper contact points while still keeping a transparent neon tester structure.

Model 319 is used for contact-type AC voltage indication in deeper wall boxes, recessed terminals, distribution panels, equipment covers, and facility service points.
The longer Φ4×120mm probe helps users reach contact points that compact or pocket testers may not access easily.
Pocket testers focus on small size and carry convenience. This model focuses on extended reach, deeper access, and a fuller 19mm handle grip.
No. The professional transparent tester is a balanced standard service model. This Model 319 version is specifically positioned for extended reach and recessed electrical point checking.
It can be supplied in blister cards, display boxes, color boxes, bulk packs, or selected electrical maintenance kits.
