The Testo 440 multifunction measuring instrument, propeller probe and hot wire probe, including the telescope, have an intelligent calibration concept, ease of use and maximum comfort for adjusting air conditioning and ventilation systems.
No task is too difficult, no too specialized application: the Testo 440 combines a compact portable instrument with intuitive measurement menus and a wide range of air probes and IAQ probes (please order separately)
• Structured metering menus for measurements in ventilation ducts or grids: the volume flow is precisely calculated due to the convenient input of the size and geometry of the cross section of the pipe. Displays: multipoint average calculation, average volume flow, current values, and min values. or max.
• Other practical measurement menus, e.g. long-term measurement, volume flow measurement, etc.
• Easy recording and evaluation of measured values. Internal memory of up to 7500 measured values, USB interface for export of data and optional printing of the measured values
• Practical magnets for easy attachment of the measuring instrument to metal surfaces (eg on pipes)
• Automatic probe detection
• Large color display with backlight
Probe probe (Ø 100 mm) with Bluetooth, integrated temperature sensor:
• Use the propeller probe (Ø 100 mm) to easily determine the air velocity, volume flow and air temperature at the anemostats in the ceilings
• Measuring range: +0.3 to +35 m / s, -20 to +70 ° C
• More applications - less equipment: the universal handle of your probe is easy to attach to other probe heads or telescopes. This allows you to expand your range of wells and save space
• Make air / grid measurements without effort and without using a ladder: Simply combine the graduated telescope probe with an angle of 90 °, extendable up to 2 m optional.
• Wireless: Bluetooth handle for greater ease of measurement and avoiding cable tangles in your bag
• Practical button on the handle: to record individual values for multipoint average calculation or to start and stop measurement series for multipoint average calculation
• Our recommendation for making accurate measurements on ventilation ducts / grids: use the probe with Testovent 417 (available separately). If you add the stream smoothing device (please order separately), you can get a high level of precision when making measurements at turbulent turbulent air flows
• Intelligent calibration concept: The Testo 440 instrument does not have to be calibrated, which ensures its permanent availability, since only the head of the 100 mm propeller is sent to the calibration.
Hot wire probe with integrated temperature sensor:
• Use hot wire probe to measure air velocity, volume flow and air temperature in ventilation ducts
• Precise measurements from 0 to 30 m / s and from -20 to +70 ° C thanks to robust sensor and automatic compensation of absolute pressure
• The graduated telescope can be extended up to 2 m to facilitate measurement in the ventilation ducts
• Use a fixed cable to connect the hot wire probe to the measuring instrument
• Intelligent calibration concept: just send the hot wire probe for calibration, so the instrument remains in use
