The bottle has a scale that extends from the neck to the ground. This scale strip is Milchigdurchsichtig. Unfortunately, that is not enough to see how much liquid during filling is currently located in. So you need a very bright light source for. (- Star)
The scale is divided into 0.5l, 0.75l and 1l. About the 1l Makierung are Makierungen% from 2%, 4%, 6%, 8% and 10%. Ideal for Neudosan (2%) All other pesticides need far less%. Even for a foliar application to bräucte no more than the 2% mark.
My previous hand sprayers from the hardware store (this would each know) one year have always maintained the highest. I hope that this Handschsprüher has a better quality.
