Testo 440 | Indoor Comfort ComboKit

Available to buy the Testo Indoor Comfort ComboKit is designed to handle all relevant measurements in order to evaluate the indoor air quality in buildings as well as the determination of the draught risk and degree of turbulence in workplace in accordance with EN ISO 7730 and ASHRAE 55. The kit comes complete with the Testo 440 air velocity and IAQ measuring instrument, the CO₂ probe with Bluetooth including temperature and humidity sensor, the wired turbulence probe and a system case.

Features

• A compact hand-held measuring instrument with intuitive measurement menus and a wide selection of air velocity and IAQ probes (optional accessories)
• Clearly structured measurement menus.
• 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. IAQ and air velocity probes.
• Large, backlit colour display
