TESTO hot wire anemometer testo 425 hot wire anemometer 0563 0425 1 unit

Catalog number: 0563 0425 Features: ● A thermal anemometer that can measure wind speed, wind temperature, and air volume. ● The probe can be extended to a maximum of 820 mm, making it ideal for measuring at high altitudes and large diameter ducts. ● Excellent for measuring low wind speeds (up to 5 m/s) and maintains a resolution of 0.01 m/s across the entire measurement range. ● Displays wind speed values ​​that are automatically corrected based on the measurements of the built-in air pressure sensor, so no correction calculations are required after measurement. ● Can be linked to a mobile app. Applications: ● For wind speed and volume in ventilation ducts, wind speed and volume at air outlets, performance testing of air filters, airflow in air environment measurements (Building Sanitation Act, etc.), wind speed of exhaust equipment (periodic voluntary inspection of local exhaust equipment), and airflow in smoking rooms (revised Health Promotion Act). Specifications: ● Measurement wind speed range (m/s): 0.01 to 20 ● Resolution (m/s): 0.01 ● Measurement accuracy (m/s): ±(0.03 m/s + 4% of measured value) ● Measurable air volume range (［［M3］］/h): 99999 ● Width (mm): 60 ● Depth (mm): 28 ● Height (mm): 135 ● Temperature measurement range (℃): -20 to +70 ● Wind speed measurement range: 0.01 to 20 m/s ● Temperature measurement range: -20 to +70℃ ● Wind speed accuracy: ±(0.03 m/s + 4% of measured value) (0.01 to 20 m/s) ● Temperature accuracy: ±0.5℃ ● Resolution: 0.01 m/s, 0.1℃ ● Backlight, hold function, maximum/minimum value, average (time/multiple points), damping function, auto-off, sound alarm, Bluetooth printer (optional), mobile app linkage, wind speed/air volume calculation ● Power supply: 3 AA batteries (included) Set contents/accessories: ● Dedicated case, batteries, shipping inspection certificate
