Volume

The nominal volume of the sprayer tank. Usually, in this case, the working volume is indicated, and not the full capacity (“for the cork”).

The more capacious the sprayer is, the more work can be done with it without refueling. On the other hand, a large volume accordingly affects the price, dimensions, and most importantly, the weight of the unit (and not only in a filled, but also in a “dry” state). Therefore, even with large volumes of work, it is sometimes more rational to use a relatively small unit, refueling it several times.

Detailed recommendations on the optimal volume of the tank for a particular situation can be found in special sources. With regard to specific values, in the most compact manual sprayers (see above), the capacity does not exceed 2 liters. Tanks for 2.1 – 5 liters can be found both in hand-held devices, and in pump-action and battery models (see "Type") with a shoulder carry. Sprayers for 5.1 – 10 liters are almost all made shoulder-mounted, the capacity of gasoline units actually starts from 10 liters, and the most capacious modern sprayers have tanks of more than 15 liters.

Max. pressure

The maximum operating pressure of the sprayer.

High pressure allows to achieve good spraying performance and range, however, actual performance can vary with units with the same pressure. Therefore, in general, the indicator is for reference (the lion's share of models has a pressure of 3 bar and 4 bar, and it is only possible to compare different models by it approximately. When choosing, it makes sense to focus on more practical characteristics — performance, range, etc.

Measuring scale

The presence of a measuring scale in the design of the sprayer.

Usually, such a scale is applied directly to the tank wall, and the tank itself is made transparent or translucent. Other design options are also possible — for example, a water metre tube with a scale built into the opaque wall of the tank. Anyway, the measuring scale allows you to determine with a fairly high accuracy how much chemicals are left in the sprayer, and without having to open the tank.

Wand holder

The presence of a tube clamp in the design of the sprayer.

Such a latch is a set of special clips, usually installed directly on the tank. It greatly simplifies the storage and transportation of the device: the handset, usually, is placed as compactly as possible and at the same time securely. Yes, and during breaks in work, this feature can come in handy — fixing the tube in the retainer is more convenient and safer than putting it on the ground, holding it in your hands, etc.
