Does my Kestrel have Bluetooth?
A Kestrel meter with Bluetooth will have the standard bluetooth symbol as shown below. If it does not have this symbol, your meter does NOT have Bluetooth. Meters without Bluetooth can NOT have it added. This is hardware and not a simple software upgrade. You would need to buy the meter with Bluetooth already installed. On the Left is the 4000 series, and on the right is the 5000 series.
