Payment Card Industry Data Security Standard (PCI DSS) Compliant.
TLS (SSL) - all data/information is secure from interception.
The testo 440 air velocity & IAQ measuring instrument recognizes probes automatically, and its structured measurement menus simplify the adjustment of air conditioning and ventilation systems. Up to 3 probes can be connected simultaneously to the measuring instrument: a Bluetooth® probe, a wired probe and a temperature probe with Type K thermocouple connector.
The versatile Bluetooth® handle allows the connection of many different wireless probe heads for all applications. In addition to this, the kit contains a CO₂ probe head and a storage case.
Structured measurement menu for long-term measurements.
Parallel determination of CO₂ concentration, air humidity and air temperature.
Absolute pressure compensation, calculation of wet bulb temperature, dewpoint and absolute humidity.
Wireless probe, internal data storage and USB port for data export.
Can be extended with a large portfolio of digital probes.
