Testo 440 Indoor Comfort ComboKit with Bluetooth®

testo 440 Indoor Comfort ComboKit with Bluetooth 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: thanks to the menu guidance programmed into the instrument, you can determine the degree of turbulence and draught risk easily and reliably, in accordance with EN ISO 7730 and ASHRAE 55. Other practical measurement menus, e.g. long-term measurement: for long-term monitoring, enter the measurement time and measuring cycle in the measuring instrument and record measurement data trends
• 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
• Automatic detection of probes, e.g. CO2 probe, turbulence probe
• Large, backlit colour display

• Measure CO2 concentration, humidity and air temperature and calculate dew point, wet bulb temperature and absolute humidity
• Accurate measurement results thanks to air density compensation via the integrated absolute pressure measurement
• Measuring range: 0 to 10,000 ppm, -10 to +50 °C, 5 to 95% RH
• The Bluetooth handle makes it more convenient to carry out your measurements and guarantees less cable clutter in the case
• Practical button on the handle: to store individual readings
• Endlessly versatile: a universal handle can be connected to all probe heads – so you can take care of more applications using less equipment, and save space too
• Intelligent calibration concept: the measuring instrument remains in continuous use, since only the probe head is sent in for calibration

• Use the turbulence probe to measure air velocity and air temperature
• Determine the degree of turbulence and draught risk according to EN ISO 7730 / ASHRAE 55
• Accurate measurements from 0 to +5 m/s within the temperature range 0 to +50 °C thanks to air density compensation via the integrated absolute pressure measurement
• Our recommendation for exceptionally easy positioning of the turbulence probe in compliance with the standards: order the measuring tripod for comfort level measurements
• Use the fixed cable to connect the turbulence probe to the measuring instrument
• Intelligent calibration concept: You only need to send in the turbulence probe for calibration

• testo 440 air velocity and IAQ measuring instrument, 3 x AA batteries, USB cable and calibration protocol (0560 4401)
