testo 405i Anemometer Handheld for Air Celocity, In-Duct Airflow and Temperature – CFM Meter with Extendable up to 15" Telescopic Shaft - Wind Meter with Bluetooth and App Operation

testo 405i Digital Anemometer handheld for measuring airflow, air velocity, and temperature on air conditioning systems Measure air velocity, temperature, and volume flow with just one instrument - the durable testo 405i temperature probe provides reliable measurements and, if combined with the smart probe app, allows remote measurement readings. With its automatic calculations, the app erases the need for error-prone manual calculations. Merely download the testo smart probe app, take advantage of user-friendly readings and create custom reports that are quickly saved and retrieved. The telescopic shaft is extendable and rotatable, making otherwise hardly accessible in-duct measurements of airflow fast and easy. The rugged housing protects the device from impact, making it extremely durable.
