Comparison SADKO SPR 20E vs Forte CL-16A

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.

The longest distance a sprayer can effectively spray a liquid or powder. Usually, the horizontal range is implied, however, for “long-range” models, values bare also given for vertical spraying — in such units, the difference between horizontal and vertical ranges can be very noticeable.

A “long-range” sprayer (for 10–15 m or more) is convenient in that it allows you to process a large area without moving, and also to reach high branches without using ladders. On the other hand, a long range requires appropriate power, which affects the price, weight and dimensions of the unit — despite the fact that such capabilities are not always required: for example, for a cramped greenhouse, an atomizer with a short range ( 5 – 10 m, and often and less) So it is worth choosing according to this indicator, taking into account the features of the planned work.

The length of the hose supplied with the sprayer.

The longer the hose, the farther the spray tube can be reached without moving the sprayer itself. However, this is true mainly for wheeled and universal sprayers (see "Carrying type"). In shoulder-mounted units, the hose is usually selected in such a way that it is enough to comfortably hold the tube in your hand, and this parameter in such models most often does not exceed 150 cm.

It is also worth considering that long hoses can be quite bulky; however, this disadvantage is often eliminated by the use of spiral hoses, which are stretched to their full length only when necessary.

The length of the spray tube supplied with the sprayer.

A long tube, on the one hand, allows you to reach far without leaving your seat and without using stools, ladders, etc.; on the other hand, it is not very manoeuvrable and can be inconvenient when working in tight spaces. When choosing, it is worth proceeding from the optimal compromise between these characteristics. For example, a large tube length (up to 2 m in some models) is useful when processing fruit trees, but for a greenhouse it is better to choose a shorter sprayer. It is also worth considering that some sprayers use telescopic (sliding) tubes, the length of which can be adjusted as needed; in such cases, the unfolded size of the atomizer is usually indicated.

Availability of a folding telescopic tube in a set of delivery of a sprayer.

The length of such a tube can be adjusted within certain limits, adjusting it to the specifics of the situation. For example, in cramped conditions, a large length is not needed, but when processing tall trees, on the contrary, it is very convenient. Specific adjustment options may be different: in some models, you can choose only one of the two extreme positions (fully folded or fully unfolded), while others allow you to fix the handset in intermediate positions.

Capacity of the complete battery in the battery sprayer (see "Type").

A higher capacity allows you to work longer without recharging, but this is true only “ceteris paribus” — the actual energy consumption (and therefore battery life) depends on the performance, range and some other characteristics of the sprayer. Therefore, only devices with similar indicators can be compared by this parameter, and it is easier to evaluate battery life by directly claimed operating time (see below). Also, larger batteries tend to weigh more and cost more. Therefore, manufacturers usually choose the battery capacity according to the features of a particular model — in order, on the one hand, to ensure good battery life, and on the other hand, not to greatly increase the weight and price.

Time of continuous operation of the battery sprayer (see "Type") on one battery charge. The actual operating time may differ slightly from the claimed one due to the specifics of a particular situation, however, these differences are usually not very large, and this indicator can be used to evaluate not only theoretical, but also practical indicators of battery life.

The total weight of the sprayer. Specified without taking into account the liquid or powder in the working tank; at the same time, for battery models (see “Type”), usually, the weight is given with a complete battery, and for gasoline models, on the contrary, “dry” weight, without fuel in the tank.
