Applications
Holiday Detector is an instrument used to detect holes in anti-corrosive coating ( Electrically Insulated ) on metallic pipes/surfaces . This test is carried before the pipes are laid underground.
Working Principle
The pipe is connected to earth ( Nominal ) and an electrode , charged to high tension , is moved over the coating at the place of a hole , arcing takes place and the instrument given alarm .
History of Holiday Detector
The term " Holiday " Dates back to the days of the great wooden sailing ships.
During the long slow voyages , ship maintenance was a must.
One of the most important duties was that of the mast sealer .
A sailor would seal the mast of the ship with tar to prevent the wood from rotting.
If the sailor missed coating an area of the mast the wood would rot.
It was said , the sailor must have taken a holiday at that point .
Thus not achieving a good coat of tar on the mast.
Later as steel replaced wood , paint replaced tar. however , Holidays live on .
Holidays also known as , pinholes voids, Discontinuities.
Performance
Holiday detector is a fully solid state device and has no moving part
Except the indicator pointer ( Digital readout can be supplied )
This has made the device maintenance - free , portable and light weight.
Measuring range - 7-30 KV

Carbon dioxide detector
· The density of carbon oxide is higher than that of air. When the carbon dioxide is low, it is not dangerous to the human body
· Damage, but when it exceeds a certain amount, it will affect the breathing of people and other living things.
· It is that the concentration of carbonic acid in the blood increases, the acidity increases, and acidosis occurs. this
· The sensor used in the instrument is composed of infrared light source, optical path, infrared detector, electric
· Optical sensor composed of road and software algorithm. Its working principle is based on different
· The near-infrared spectroscopy of gas molecules selects the absorption characteristics, using gas concentration and absorption

Product Features:
Gas leak detector is a gas concentration detection instrumentation tools, mainly refers to the portable / handheld gas detector. Mainly by the gas sensor to detect gases present in the environment, the gas sensor is used to detect the content of gas components and sensors. Generally, the gas sensor is defined as the detection target based on the classification, i.e., any sensor for detecting the concentration of gas components and gas sensors are known, whether it is physically or chemically. For example, the gas flow sensor detects a gas sensor is not considered, but the thermal conductivity gas analyzer has a gas sensor that are significant, although they are sometimes used broadly consistent detection principle.
