The type of spraying for which this nozzle is especially good. ?
What is “band spraying?” return
This type of nozzle provides thorough coverage of the target site. ?
What is a “full or solid cone?” return
This type nozzle often is used for applying insecticides. ?
What is a “hollow cone?” return
The type of nozzle shown requires this type of pressure and range of pressure. ?
What is “low, 10 to 40 PSI?” return
The XR designation on this nozzle stands for this. ?
What is “extended range?” return
The percent overlap recommended for this type of nozzle. ?
What is “30?” return
The two orifices here are oriented in these directions to improve penetration of the spray. ?
What are “slightly forward and slightly backward?” return
This is the percentage by which your pesticide exposure is reduced when you use the PPE shown above. ?
What is “85?” return
This is the very flexible, but strong, material commonly used now for certain PPE, like that shown here. ?
What is “nitrile?” return
This lightweight material is a common fabric for suits like the one shown here. ?
What is “tyvek?” return
You almost always need the type of PPE shown here when you are doing these two things. ?
What are “mixing and loading?” return
The mask type of PPE shown here only protects you from inhalation of these two forms of pollutants. ?
What are “mists and dusts?” return
This is the maximum time for which the cartridges in the type of PPE shown here are effective. ?
What is “8 hours?” return
This is the five- word name for this type of PPE. (FFAPR) ?
What is “full face air purifying respirator”? return
This dual- function device is always located between the pump and the output site. ?
What is a “pressure relief/regulator valve”? return
This type of nozzle uses a combination of off-center and other nozzles to produce a very wide spray swath up to 60 feet. ?
What is a “boomless nozzle”? return
A graduated cup is used for this two- word process to make sure each nozzle on a boom is applying within a specified range. ?
What is “measuring output?” return
This device, often installed between the tank and the pump, has a three-word name. ?
What is “an in-line strainer”? return
Du to its unusual pattern, this nozzle type often is used in post-directed applications to spray up under crop foliage. ?
What is an “off-center nozzle”? return
In addition to providing for quick-connect nozzle mounting, this assembly also has this inside to help prevent leakage. ?
What is a “diaphragm check valve?” return
This is the complete four- word name for this device, which is rated as ”100.” ?
What is a “100-mesh nozzle strainer”? return
On the spreader shown, this is the part that actually disperses the chemical. ?
What is a “spinner?” return
The equipment and function, measured in GPM, that this device checks on a sprayer. ?
What is “nozzle flow rate?” return
The output tolerance range, in percentages, for nozzles across a boom ?
What is “plus or minus 10 % of the average?” return
To double output you must do this to the pressure. ?
What is “quadruple it?” return
The two-word name for the device shown below, which is very handy for preparing for accurate chemical application. ?
What is a “calibration calculator?” return
