The 440013 Heavy Duty Mainstester is a mains testing screwdriver with an extended shaft for long reach applications, indicating the presence of voltage from 120-250V AC. The one-piece moulded blade and handle is fully insulated for protection when checking potentially live circuits, and a permanently sealed resistance neon tube gives a clear, high visibility indication when voltage is present. The long pattern chrome vanadium blade reaches recessed terminals that a standard length mainstester cannot.

When should I choose the 440013 over the 440007 mainstester?
Choose the 440013 when you need extra reach: its long pattern 4 x 100 mm blade accesses recessed terminals, while the 440007 has a shorter 3 x 65 mm blade and adds a pocket clip for everyday carry.
