Total THT291908 identifies live AC voltage between 100V and 500V. This 190mm test pencil uses a hardened SL4 metal tip for circuit detection. The 190mm length replaces the 140mm of the THT291408, providing 50mm of extra reach. Tip width increases to 4mm from the previous 3mm for improved screw engagement.
Key Features
- 190mm Extended Reach: 190mm total tool length. Accesses screws inside deep-set switchboards or narrow conduit gaps.
- High-Visibility Neon Indicator: Integrated neon bulb. Signals live current with a clear glow during load shedding.
- Insulated Transparent Handle: High-grade plastic insulation. Blocks current flow to the hand during 500V circuit checks.
- SL4 Hardened Metal Tip: 4mm wide slotted steel tip. Fits terminal screws without slipping or stripping the metal.
Frequently Asked Questions
How to use Total THT291908 test pencil?
Touch the tip to the contact point while keeping a finger on the handle's metal cap. The neon bulb lights up when detecting a live phase.
Is Total THT291908 safe for 500V?
This tool handles AC voltages up to 500V. Internal resistors limit current to safe levels for the operator.
