Testo 425 Anemometer with Telescopic Probe – Hot Wire Anemometer Handheld for Air Flow Temperature Measurement in Ventilation Ducts – Range of 0.01 to 5906 fpm – Airflow Meter with App Compatibility

The Testo 425 Anemometer – Quick & easy determination of Air Flow and Temperature Measurement in Ventilation DuctsWith the 425 Anemometer control of air quality of in-duct systems has never been more convenient or precise. Thanks to the app compatibility, the air temperature thermometer is set up and configured in minutes and ready to go. In addition, the App not only supports you in configuring the measuring instrument and takes over display, storage and documentation of the measured values – it also turns your smartphone into a second display.Time and point average values are automatically calculated allowing for a fast determination of the airflow and velocity. The cable-connected telescope can also be extended up to 820 mm, making it easier to work overhead or in large diameter ducts.Technical Data:Temperature – NTC Measuring range: -20 to +158 °F / -20 to +70 °CAccuracy: +-0.9 °F / +-0.5 °CResolution: 32.2 °F / 0.1 °CVelocity - Thermal anemometer Measuring range: 0.01 to 5906 fpm / 0.01 to 30 m/sAccuracy: +-(5.91 fpm + 4.0 % of mv) (0.01 to +3937 fpm) / +-(0.03 m/s + 4.0 % of mv) (0.01 to +20 m/s) / +-(98.4 fpm + 5.0 % of mv) (20.01 to +5906 fpm) / +-(0.5 m/s + 5.0 % of mv) (20.01 to +30 m/s)Resolution: 1.97 fpm / 0.01 m/sWeight: 9 oz. / 268 gDimensions: 5 x 2 x 1 in. / 135 x 60 x 28 mmOperating temperature: -4 to +122 °F / -20 to +50 °CProbe: -4 to +158 °F / Probe: -20 to +70 °CHousing: ABS + PC / TPEDiameter probe shaft: 0.295 in. / 7.5 mmCable length: 4.921 ft. / 1.5 mProtection class: IP40, IP20Length probe: 7.087 in. / 180 mmBattery type: 3x AABattery life: 35 hStorage temperature: -4 to +122 °F / -20 to +50 °CScope of delivery:testo 425, Transport bag, Calibration protocol, 3 x AA batteries
