1, what is ultrasound?

answer: when the object vibration will sound, scientists will be the number of vibrations per second is called frequency of sound, it is measured in Hertz, when objects beyond a certain frequency of vibration, which is higher than the range of human hearing, people will listen to not to come out, this is called "sound ultrasonic", the range of the human ear is 16HZ - 20KHZ, although humans cannot hear ultrasonic, but many animal have the ability, bats emit ultrasonic ranging from 2 to 100000 Hz the hunt for food or avoid dangerous objects, this is like a "radar" activity, bats are to find the target utilization the "radar", to catch insects. We human beings until the first World War to learn the use of ultrasound, which is the use of the principle of sonar to detect the target and its state, such as the position of the submarine, etc..

ultrasonic can penetrate obstacles, strong directivity, short distance dispersal, attenuation fast characteristics. Ultrasonic route of transmission is by surrounding objects numerous times reflection of propagation and the formation of ultrasonic door network covering the entire control

2, what is the ultrasonic wave vermifuger?

A : ultrasonic mouse expelling device is a using frequency acoustic pulse circuit technology, and after years research on hearing of rodents in the scientific community, developed the ability to produce a device 13kHz-55kHz ultrasonic, the device of ultrasonic can effective attack rodent auditory system and can lead to physiological disorder of rodents. This technology comes from the advanced pest control idea in Europe and America. The purpose is to create a good quality space, which has no rat, no pests, and to create the environment which can not survive.

3, ultrasonic really can be repellent?

Answer: mice, this kind of animal bats are based on ultrasonic wave communication, the rodent auditory system is very developed, very sensitive to ultrasonic, can determine the source of the sound in the dark, in the ultrasonic can send out when threatened 30-50kHz, will be able to rely on a ultrasonic wave and echo back to the nest in no eyes, adult rats can emit ultrasonic for help in a crisis, when mating can also emit ultrasonic said happiness, can be said that ultrasound is a rodent language, so we can use high power ultrasonic interference and effective stimulation of insect auditory system, so that it can not endure, and feel panic, stay. Convulsions and other symptoms, so as to achieve the purpose of preventing rodents from range.

4, why vermifuger I used to buy no effect?

answer: the following may affect the use of effects:

first is distribution and goods layout, room walls, or objects (obstacles), if the items in the control area placed the density is too high, or goods stacked directly on the ground, or have too many dead ends, and partition walls, such an environment should increase in insecticide use quantity, must have high energy ultrasonic covering in order to achieve the repellent effect.

second is repellent and placement also has the very big relations, flooding in the placement is not good, a reflecting surface formed less when it will weaken the effect of mouse drive, should as far as possible to be repellent device placed in a place is capable of producing more reflection, refraction wave. Third is control space is too large, the use of insecticide quantity is not enough, cannot control comprehensive coverage of words, repellent effect is not ideal, this should also be the increase in the number of insecticide, strengthens ultrasonic attack density party can achieve the best repellent effect.

A , working principle:

- this product adopts high-tech means, can produce a very special ultra low electromagnetic wave. Through the transmission of its own components and power lines, can effectively stimulate the control range of cockroaches, ants, spiders, fleas, bugs and other pests of the nervous system and the auditory system, so that it is not appropriate to escape.

] this product according to the principle of ultrasonic, fixed and variable frequency ultrasonic and effectively get rid of the indoor rats and mosquitoes and other pests.

Two, the scope of application:

- this product is suitable for families, restaurants, hotels, hospitals, office buildings, farms and other places.

] this product is a ultrasonic control effectively drive range at about 100 square meters; electromagnetic wave driving range at 120 ~ 150 square meters;

Three, product features:

The ] this product electromagnetic wave, solid multiple frequency ultrasonic frequency and ultrasonic technology under the jurisdiction of the range of all kinds of pests to drive them away.

- this product adopts the microcomputer chip and electronic integrated circuit, the appearance of small beautiful, easy to use.

Stable performance, - the product function is strong, quick.

] this product is a super low frequency electromagnetic waves can effectively penetrate walls, not due to items barrier and reduce the use of effects; ultrasonic non function through the wall.

] this product is a super low frequency electromagnetic wave only the insects, on the human body, home appliances and home reared pet will not lead to the any adverse effects.

Four, method of use:

- this product will be directly inserted in the 220 volt power supply socket, switch, select the desired operating mode can be.

Five, note:

Please use the socket on the wall and placed in parallel with the wall - when using this product.

- mostly because of pest on the ground, so this product should be installed in a position close to the ground.

- this product is only suitable for indoor use, do not damp and at high temperature.
