This unique accessory can be used with any of our backpack and compression sprayers.

This innovative valve, featuring a trigger mechanism and application pipe, easily attaches to any standard sprayer to deliver precise, consistent volumes of fluid with every squeeze. Its pressure-retaining system ensures reliable performance regardless of pressure fluctuations in the sprayer. The delivery volume is fully adjustable between 2 ml and 25 ml per stroke, allowing for exceptional control and repeatability with each trigger pull.

Once calibrated correctly this allows for the rapid dosing of potted plants and seedlings. When potentially thousands of plants need treating every day the Dosimeter Valve not only saves time and effort but also reduces chemical waste considerably.

• Can be calibrated to deliver between 2ml and 25 ml of fluid per stroke
• The same fluid is delivered regardless of backpack pressure
• Improved safety for the operator as the spray is directly only at the plant
• Reduced chemical waste
• Gives completely consistent dosing

NOTE: If a lance extension is required then any of our lances compatible with the S5 valve can be fitted to the dosimeter. The lance extension is commonly used with The Dosimeter for spraying at the base of saplings to combat wood weevil.
