Max. spraying distance
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.
Spray wand length
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.
Wand material
The material from which the complete spray tube of the sprayer is made.
— Plastic. The key advantage of plastic over other materials used for spray wands is its low cost. In addition, this material is chemically inert and does not corrode, and also has a low weight. On the other hand, the rigidity of the plastic is not very high, which is why such tubes tend to bend, sometimes even under their own weight.
— Aluminium. Aluminium alloys combine good strength and lightness, such a tube is easy to work with, and it takes quite a strong blow or pressure to bend it. On the other hand, aluminium is expensive.
— Brass. In addition to strength and reliability (including resistance to bending), brass is notable for its excellent resistance to corrosion. The disadvantages of such tubes are the high price, as well as the rather large weight.
- Stainless steel. "Stainless steel" is notable primarily for its high strength and rigidity, which is superior to other materials, despite the fact that this material is relatively inexpensive. However, such tubes weigh much more than aluminium or plastic ones.
- Copper. According to the main operational properties, copper pipes are similar to brass ones: they are strong, reliable and durable. On the other hand, such tubes are relatively expensive and do not have fundamental advantages over the same "stainless steel". Therefore, this option is rarely found.
Spray lock
A device that allows you to fix the trigger (switch) of the sprayer in the pressed position. This is especially convenient for large volumes of work: holding the trigger manually for a long time is rather tiring, and
the continuous watering lock allows you to avoid unnecessary stress on your hands.
Note that this feature can be found in all types of sprayers (see above), including lever ones — many models with this type of action are equipped with both a pumping lever and a separate trigger that must be kept pressed during operation.
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.
Replaceable nozzles
The ability to change nozzles — sprayer working nozzles.
Different nozzles differ primarily in terms of spraying distance and width of the plume, as well as the degree of spraying (particle size). In addition, specific nozzles can be used in sprayers — for example, for working with powder. Replacement nozzles are usually included in the delivery, but this point (as well as the range of nozzles) is still worth clarifying separately.
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.
Weight
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.
