Crosswind & headwind
Drift risk is measured against the passes you fly, not just a raw wind speed number.
Kestrel 5500AGSOL-CS & AIRAg ready
Kestrel 5500AG agricultural weather meterLiNK with rotating vane mount
The full spray measurement set with crosswind, headwind and density altitude — plus on-board logging that keeps its own records.
- Resolves crosswind and headwind / tailwind against the passes you actually fly
- On-board logging — leave it mounted in the field for days or weeks, unattended
- Pairs directly with SOL-CS and AIRAg SOL-CS, so the logged series lands on the job record
- Rotating vane mount and carry case included
- Waterproof to IP67, drop-tested to MIL-STD-810G

Fully integrated
This meter is built into both SOL-CS and AIRAg SOL-CS.
Switch it on and the readings land on the job you are working — time-stamped, tied to the treatment area, ready for reporting and audit.
Why it matters
Spray within conditions you can prove.
Off-target drift damages neighbouring crops and puts people, livestock and wildlife at risk. Measuring at the site of application — at boom height — and documenting it is the difference between a defensible record and no record at all.
Logging without a phone
On-board memory records readings at your interval — unattended, time-stamped and ready to export.
Density altitude & air flow
Station pressure, density altitude and CFM add aircraft performance checks to the spray values.
Instrument
What it measures and does.
A high-contrast, sunlight-readable display switchable between °C/°F, km/h, m/s, mph, ft/min, knots, Beaufort and Delta T.

5500AG or 3550AG?
Both meters measure the same spray conditions and both pair with SOL-CS. The 5500AG adds component wind calculations, station pressure and density altitude, and logging that runs on the meter itself.
