Advantages of «Grad A-550US»:
1.
Large protection range - up to 550 square meters.
Such an astounding range became possible by virtue of increasing power of transducer and upgrade algorithm of generate ultrasonic radiation. The device is appropriate for repelling pests both at large areas, and at small ones. The smaller an area the higher effectiveness of the device because in this case all power of repeller concentrates on small volume.
2.
Silent operation
Unlike most similar devices,
«Grad A-550 US»produces no sounds! This has to do with the fact the repeller uses ultrasound which doesn't affect people.
3.
The effectiveness of the device doesn’t decrease with time because pests cannot adapt to nonrepeating sequence of ultrasound.
Laboratory experiments on pests show that prolonged exposure to changeless frequency gradually stops to effect on pests and they stop perceiving it as a signal to escape. However «Grad A-550 US» uses unique nonrepeating sequence of ultrasound which has no addictive effect for mice, rats and moles. So the device will protect your territory for many years.
Also it works without "blind spaces", without reducing effectiveness in zones where pests can hide.
4.
Grid-isolated mode
«Grad A-550 US» can operate not only from electrical grid 220 volts but also from alternate supply (batteries type AAA, extraneous source of direct-current of voltage 10-30V, for example a car battery). By virtue of variety of powering the device can be used almost everywhere: in unelectrified places (sheds, basements, cold cellars), outside, underground (for repelling moles).
However, it must be taken into account that when the device powering from batteries, the power of emitting automatically decreases (it needs to save battery’s charge).
5.
Dependable shatter-proof case
The repeller’s case is made of shatterproof plastic that’s why the device resilient to the effects of physical impacts (drop from a short height, not very strong hits).
6.
Operation at the widest range of temperature
Area of application «Grad A-550 US» is very wide:
- factory facilities (plants, factories, warehouses, bakeries, cafes, restaurants, cattle ranches, chicken ranches)
- domestic compartments (separate houses, cottages, cold cellars)
- for protection of underground utility system, cables, hangars and lift shafts
- Outside – for protection yards and playgrounds.
- The device in vacuum packing can be places underground on depth 10 centimeters (3,93 inches) into a mole’s hole, transducer must be directed to thehole. In this case the repeller operates from batteries.
