TESTO Multi-Environment Measuring Instrument testo 440dP Main Unit (Differential Pressure Sensor Built-in) 0560 4402 1 Unit

Catalogue number: 0560 4402 Features: ●A multi-instrument that can handle all major environmental measurement items. ●A differential pressure sensor is built in, and it can also measure differential pressure using a pitot tube. ●In addition to displaying three items simultaneously on the color display, the easy-to-understand operation menu allows for intuitive operation. ●Measurement data can be saved in the built-in memory of the main unit and exported to a PC in CSV format. ●Up to three types of probes (wired, wireless, K thermocouple) can be connected simultaneously. ●The menu structure is simple, and measurements can be made immediately after startup in just two or three steps. ●The wired/wireless handle can be connected to all probe heads, and by replacing the probe head, it can be used for a wide variety of purposes at low cost. ●Measurement values ​​can be logged at intervals of 1 second or more. Applications: ●For ventilation and air conditioning. ●For measuring indoor air quality.
