The Testo 0554 1111 Bluetooth Handle facilitates measurements without any bothersome cables: readings are transmitted directly to your measuring instrument via Bluetooth. Combine the handle with different probe heads (sold separately) to easily expand your portfolio of probes.

Via Bluetooth, readings are transmitted to your measuring instrument (sold separately) from a distance of up to 65.5 feet (20 m). Operate the measuring instrument by simply pressing the button on the handle - for example, to store individual readings.

Please note that a handle adapter (sold separately) is required to connect probe heads for air velocity measurement or the extendable telescope for air velocity measurement to the handle.
