Auto Sensor 450ml Sanitiser Dispensers are a touchless design to minimise cross infection. They use infrared technology and are easy to refill. Put them at the entrance to your office or warehouse, or you can use the included wall mount bracket and screws to apply to a wall. They are powered by 4 AA Batteries (not included) and also feature 4 different settings to the amount of sanitiser you want to dispense. Place them at entry and exit points to your workplace to ensure maximum safety for your staff and clients. Simply put your hands under the dispenser and it will release a pre-determined amount of sanitiser. Simple!
