What is an NCV non-contact measuring pen?
Cable breakage can be said to be one of the most common cable faults in daily cable comprehensive wiring installation and maintenance work. However, in actual engineering maintenance and repair, for many maintenance personnel, encountering a broken wire or cable in the middle is a headache. When the internal medium of the cable breaks, due to the obstruction of its external insulation skin, we cannot see the exact location. This is the case in both strong and weak current states, and it is difficult for maintenance personnel to safely and efficiently determine the location of the break point.
With the progress of science and technology, various efficient detection tools have emerged, and this problem has been effectively solved. Among numerous testing tools, the compact and portable NCV non-contact testing pen is a testing instrument with a high frequency of application.
NCV non-contact measuring pen
NCV "is the abbreviation for NON CONTACT VOLTAGE, meaning" non-contact voltage detection ". It is used to determine whether the tested object is live or not, that is, to detect whether there is electricity (live wire) in the wire without breaking the wire skin or touching the electrode. The NCV non-contact test pen uses electromagnetic field induction detection technology to achieve non-contact detection of whether an object is charged. It can be used to find live wires buried in walls, or to find buried broken wire ends, suitable for use with higher AC voltages. Only determining the presence of voltage cannot measure the specific voltage level.
Usually, NCV non-contact test pens can also be used to distinguish the zero and live wires of sockets. When a live wire is detected, there will be an audible and visual alarm, but there will be no audible and visual alarm when detecting the zero wire.
NCV non-contact testing pen is so practical, we need to buy it quickly for use on the machine! But there are so many styles and models on the market that it's easy to be picky. Can you directly recommend a product with strong performance and simple operation?
CEM Huashengchang AC-15EX/AC-15EXS explosion-proof NCV non-contact measuring pen is quite good!
High and low voltage measuring pens are a regular tool for maintenance and inspection. Among numerous test pens, NCV non-contact test pens are widely used due to their high safety and measurement efficiency. Huashengchang's AC-15EX/AC-15EXS is not only safe to use and compact in size, but also has explosion-proof function, which can meet people's high demand for safe and normal measurement in potentially explosive environments.
