The 3550AG is an agriculture specific version of the powerful Kestrel 3000 series, measuring temperature, wind speeds, barometric phenomena and pressure trends. Off-target herbicide or pesticide drift can not only cause damage to nearby vulnerable crops but also pose a serious threat to people, livestock, wildlife, and the surrounding community.

For councils and arborists the 3550AG provides valuable data for both tree planting and tree felling operations. In the agricultural sector; farmers put themselves and their operations at risk every time they spray a field without documenting the wind speed and environmental conditions. The 3550AG with Bluetooth® Connectivity makes it easy to instantly capture and log accurate, field-level weather data with just one-click.

No matter the size of your operation -- effective herbicide and pesticide application is critical to your success. Prevent drift, eliminate waste, ensure safety and effectiveness – it all starts with monitoring your conditions.

The new 3550AG meter has Bluetooth connectivity to pair with the Kestrel app for the ability to wirelessly view, share, and export weather data from a mobile device - the APP is available in both the Android and Apple stores. For record-keeping, conveniently email the data from the APP to an email account; data will be attached as a CSV file.

Stock Control & Pricing Breaks

Our webstore now indicates an approximate level of items in stock. This is indicated as quantity breaks as follows: 1+, 6+, 12+, 36+, 100+, 250+, 500+, 1000+, 2000+ and 3000+. For example: if we have 5 ARS Florist Scissors in stock this would display as 1+ — if there are 47 in stock it will indicate 36+. As another example: if we have 14,960 Fluted Tree Guards in stock this would indicate as 3000+. The quantity also indicates the number of items as described by the product description; so Florist Scissors are sold individually whereas the 10L Carton Tree Guard is sold in boxes of 150 – in the later case 100+ items refers to 100+ boxes of 150 (or over 15,000 Carton Tree Guards in stock).

Please note: our webstore stock levels are accurate to within the last hour; if you order an item that has since sold out, we will promptly notify you as to when your order will be fulfilled. Some items may be indicated as Special Order items or display a custom message as to when stock is due.

Pricing breaks: many items in our store display pricing breaks. The number of items indicated in pricing breaks can vary a lot between different products. Often with horticulture tools such as secatuers and loppers, the pricing breaks may relate to the number of items in a box or total number of items in a carton; so if you need several secateurs, and order per box or carton, you save more as we save time packing your order. Items such as tree guards, bamboo canes and hardwood stakes often have price breaks set to fill a standard palette size; thus savings or efficiency gains are made in the storage and transport of these items.
