Description

The Testo 440 dP Air Velocity and IAQ Measuring Instrument with Differential Pressure Sensor (Product No. 0560 4402) is a multifunction tool for HVAC and IAQ professionals. It combines the functions of a versatile meter with an integrated differential pressure sensor, eliminating the need to carry multiple devices. The instrument works with a wide range of Bluetooth and cabled probes, sold separately.

Key Features

• Intuitive operation: Clearly structured measurement menus guide users through specific applications, including duct and outlet measurements, turbulence assessment (EN ISO 7730 / ASHRAE 55), comfort level measurement (EN ISO 7730 / ASHRAE 55), long-term IAQ monitoring, and mould detection.
• Wireless convenience: The use of Bluetooth probes provides flexibility and reduces cable clutter, allowing measurements to be taken up to 20 meters away.
• Efficient documentation: Up to 7,500 measurement protocols can be stored in the instrument's internal memory and exported to a PC via a USB port. An optional Bluetooth/IRDA printer is also available for on-site printing.
• Intelligent calibration concept: Only the probe heads need to be sent for calibration, allowing the main Testo 440 dP instrument to remain in continuous use with other probes.
• Broad probe compatibility: The Testo 440 dP works with a comprehensive range of probes, including wireless Bluetooth probes and wired versions, to measure various parameters
