Model 999 is the standard transparent voltage tester in this product group. It should not be written as a pocket tester, slim tester, long shaft tester, or industrial panel tester.
The key value of this model is balance. Its 185mm length gives more body size than compact models, while the 35g weight gives a stronger service feel than lightweight test pens. The 17mm handle diameter keeps the shape familiar for transparent tester buyers.
This page should focus on standard professional supply, not broad electrical use. Model 999 is suitable when buyers want one regular transparent voltage tester for retail shelves, maintenance kits, and OEM product lines.
Choose Model 999 when the buyer needs a normal-size transparent tester that looks more professional than pocket models but does not need the extra length or weight of Model 936.
It is best positioned as a stable middle option for distributors who need a recognizable transparent electrical tester with AS handle, neon indicator, and 40Cr probe.

No. Model 999 is a standard service-size model. Slim models should focus on narrow handle diameter and lighter body weight.
