Testo 440 Hot wire Kit

testo 440 Hot Wire Kit in detail

• No task is too challenging, no application too specialized: the testo 440 combines a compact hand-held measuring instrument with intuitive measurement menus and a wide selection of air velocity and IAQ probes (please order separately)
• Clearly structured measurement menus: the volume flow is precisely calculated thanks to convenient input of the size and geometry of the duct cross-section. Timed and multi-point mean calculation, average volume flow, current reading and min./max. values are displayed
• Other practical measurement menus, e.g. long-term measurement, volume flow measurement with a funnel, etc.
• Easy storage and evaluation of measurement data. Measurement data memory for up to 7500 measurement protocols, which can be read via a USB port and further processed as a CSV file on the computer (e.g. with Excel)
• Practical magnets for easy attachment of the measuring instrument to metal surfaces (e.g. ducts)
• Automatic detection of probes, e.g. hot wire probe
• Large, backlit colour display

• Use the hot wire probe to measure air velocity, volume flow and air temperature in ventilation ducts
• Accurate measurements from 0 to 30 m/s and -20 to +70 °C thanks to the robust sensor and automatic absolute pressure compensation
• Telescope that can be extended to 0.85 m, with scaling, makes it easy to measure in ventilation ducts
• Use the fixed cable to connect the hot wire probe to the testo 440 air velocity and IAQ measuring instrument
• Intelligent calibration concept: the air velocity and IAQ measuring instrument remains in continuous use, since only the probe is sent in for calibration

• testo 440 air velocity and IAQ measuring instrument, 3 x AA batteries, USB cable and calibration protocol
• Hot wire probe (Ø 9 mm) with fixed cable (length 1.7 m) including temperature sensor, with telescope (can be extended to 0.85 m) and calibration protocol (0635 1032)
• Basic case for testo 440 and 1 probe
