Gas concentration detector is a gas leak detection instrumentation tools, including: portable Gas Detector, portable gas detector, Fixed Gas Detector, on-line gas detector, etc.Gas sensors are used to detect the types of gases in the environment. Gas sensors are used to detect the composition and content of gases.

It is generally believed that the definition of a gas sensor is based on detection of target classification, that is, those who used to detect gas composition and concentration of sensor is called gas sensor, whether it is to use physical methods, or with chemical methods.For example, detection of gas flow sensor is seen as a gas sensor, but it belong to important thermal conductivity type gas analyzer gas sensors, although they sometimes use broadly consistent detection principle.
The farmers abandoned the corn planter because the water was too expensive.
[ China agricultural machinery network industry news ] water is very expensive, can save and save, for this, Zhang Laohan gave up the machine sowing, "the ground is too dry, if you use the corn planter, you have to pull the water, spin, live, It takes too much water and is reluctant."
"I am a few acres of land, thanks to this living pond." In early June of 2017, in a rural area of ​​Jiaodong, the farmer Zhang Laohan played with a long pumping pipe, prepared to pump water and drought-resistant corn, and his tired face was somewhat proud. "The sky is so dry, so many reservoirs and dams are dry, but fortunately this bay is awesome."
The farmers abandoned the corn planter because the water was too expensive.
The south and the north are dry, the rains are frequent in the south, but the north is drought for four years. The current weather is increasingly invisible. However, in the north of the country, there is water in the area of ​​cultivated land, and there is hope for a bumper harvest.
Small water pumps and tricycles that pull water are all necessary production tools in rural areas, almost every family. In the past few years, the peasants have long abandoned the hope of the wind and rain. They can only find their own way, pumping wells and pouring water.
The water is very expensive, and it can save and save. For this reason, Zhang Laohan gave up the machine sowing. "The ground is too dry. If the corn planter is used, it will have to pour water, spin tillage, live broadcast, and consume too much water. â€
"Now the people in the village pull the water to artificially plant corn, basically no use of the planter, the cost can not afford." Zhang Laohan removed urea and other fertilizers from the tricycle, said that can not waste water, fertilize together when planting corn.
The artificially ditched water was carefully watered, and the thirsty land quickly swallowed the water. Zhang Laohan then manually sprinkled the corn seeds and fed the fertilizer.
Some people have seen that farmers abandon the planter and say that the peasants are backward, their thoughts are rigid, and they cannot accept new things. This is irresponsible. Farmers welcome more agricultural machinery as long as conditions permit.
Artificial crops, in this hot summer day, is really not a taste for the average person. Zhang Laohan, who is already 60 years old, has a sweaty face on his face, and then he uses the big cockroaches to cover the seeds and fertilizers.
A small, moist, small ditch that is drought-resistant at the foot, like the traces of sweat and tears from the face of the dust.
The suffering of the peasants is only known to the peasants. "First planted, so I can get out of the seedlings. God can't always rain without it? It's not really good, then I will say it again." Zhang Laohan wiped the sweat on his face, and his face was helpless and stubborn.
“Is it worthwhile to grow corn for the sake of corn? In this year, it’s worth the money? Rural people can’t let the land idle, plant corn, raise chickens and raise geese at home, and eat. The corn is cheaper, 8 hairs. It’s also painful to buy it.â€
The peasant, own peasant's own small abacus. The temper is not farming, it is all standing and talking, no pain, the old peasants can do as long as they can do it.
