Why use THT1909 Test Pencil?

THT1909 Test Pencil

THT1909 Test Pencil is made of ABS, and it is safe and non-toxic. 1. No ink smudges on the page, your clothes, or your hands. 2. It’s much easier to draw with a pencil than with a pen — and much of my note-taking involves drawing things along with writing words.

250 V / DC 1.5-36 V
Slotted size: 4 x 133 mm
Induction test to find phase line, ground line and breakpoint of phase line
No need to install battery
Packed by double blister

Non-contact voltage detectors
Amplified electronic testers (informally called electrical tester pens, test pens, or voltage detectors) rely on capacitive current only, and essentially detect the changing electric field around AC energized objects.
Tester has neon bulb that requires around 70 volts to glow. There is high value resistor in series to keep current minimum to avoid shock to the person using it. Phase or ‘Line’ has 230V with respect to earth
Pencils are better for shading. Marks made with pens last longer. Pencils are more environmentally-friendly than pens. Pencils need sharpening, while pens are always ready to write.
Graphite molecules are flat groups of carbon atoms that are stacked in layers. The layers slide against each other and allow the lead to slide off the pencil point and onto the paper. When you erase with a rubber eraser, the graphite in the lead sticks to the rubber better than it does to the paper.
