"Grad А-650D" rodent repeller with a HYBRID ULTRASONIC system was developed specifically based on user reviews of the "Grad A-550 US" and "Grad A-500".
It combines a unique dynamic ultrasonic mode and an additional sound + ultrasonic mode. This allows the device to be used both in silent mode and in 2X mode for places where ultrasound cannot penetrate or its effect is weakened by various obstacles.
A high degree of efficiency of its operation is achieved by using a special algorithm of sound alternation, which eliminates the habituation of rodents to the device’s action. Sound and high-frequency impulses affect pests’ nervous system, as a result, they leave their habitats, moving away from the sound source to a safe distance.
The device emits an audible noise in combination with ultrasound, which enables it to penetrate walls. This allows to scare rodents that are inside or outside the walls.
Competitive advantages of the "Grad A-650D":
- A non-repeating sequence of sound and high-frequency waves in the ULTRA-WIDE range from 4 to 40 kHz is used to deter rodents. This eliminates the possibility of habituation, which often happens when using cheap Chinese-made repellers. When the signal changes, animals cannot adapt quickly, as a result, they leave their habitats. In addition, a deterrent signal with the usage of sound frequencies is more effective in premises crowded with furniture.
- The patented sound pattern allows to eliminate the effect of "fading sound"* completely. As a result, there are no areas where rodents can continue to live. This also makes it possible to use several repellents in one premise to extend the range of action.
*The fading effect is a physical phenomenon that occurs when an echo and a signal source or two signal sources weaken each other. As a result of this phenomenon, there is an area of silence, that is, a place where there is no signal. - High hybrid sound signal strength. The effective area of the device is up to 6996 sq.ft. (650 sq. m.) With our repeller, you can expel rodents even from large premises (warehouses, granaries, hangars, etc.). This sound passes through the walls and allows to influence on all hidden areas where rodents are present.
- Autonomous use. The device is designed for autonomous operation in places where there are no electrical mains (in cellars, basements, on the street). The device can be powered by batteries. The power adapter is used to supply the device with power from 110/220 V mains. It is also possible to supply a car adapter (optional) for autonomous power supply of the device from a standard car battery.
APPLICATION AREAS
- Indoors (if there are no people living nearby). The device can be used in livestock and poultry farms, vegetable and grain storage facilities, warehouses, factories, spas, restaurants, shops, camp sites, etc. It can be used to protect tunnels, elevator shafts, hangars, underground utilities and corridors. In domestic conditions: to protect cottages, houses, apartments, cellars and basements, gardens.
- Indoor installation with an orientation towards the outside. If it is necessary to protect open areas (gardens, fields, plantations, vineyards), the device can be installed indoors near the window towards the protected area.
Grad A-650D can be used in granaries, storages, industrial and commercial premises, shops, cafes, restaurants, warehouses, as well as in everyday life (at cottages, in country houses, cellars, barns).
Grad A-650D does not require any special knowledge during installation and use. It is enough to get acquainted with the user manual, install the device according to the recommendations and turn it on.
