Selkäruiskutin

A selkäruiskutin, which translates to "back sprayer" in English, is a type of spray applicator worn on the back. It is commonly used for applying liquids such as pesticides, herbicides, fertilizers, and disinfectants in agricultural, horticultural, and public health settings. The device typically consists of a tank that holds the liquid, a pump mechanism to create pressure, and a nozzle for directing the spray.

The tank is usually made of durable plastic and is designed to be carried comfortably on the user's back using straps. The pump can be operated manually, often through a lever or piston action, or it can be powered by a battery or small engine for larger or more frequent applications. The nozzle is adjustable, allowing the user to control the spray pattern, from a fine mist to a coarse spray, and the range of application.

Selkäruiskutin are valued for their portability and ability to cover relatively large areas efficiently compared to handheld sprayers. They allow for hands-free operation of the spraying mechanism, freeing up the user's hands for other tasks or for better control of the application. Maintenance usually involves cleaning the tank, pump, and nozzle after each use to prevent clogging and corrosion, and ensuring that any seals or moving parts are in good working order. Safety precautions, such as wearing appropriate personal protective equipment, are crucial when handling chemicals with a selkäruiskutin.
