Testo 440 dP Data Logging Air Quality Monitor for Air Velocity, Temperature, +1370 (Temperature-TC) °C, +150

This air quality monitor from Testo measures air velocity and IAQ (indoor air quality) to help you maintain a contaminant-free environment. This device is compatible with Bluetooth probes, wired probes and type K thermocouple probes to measure a broad range of parameters. It comes with automatic probe detection technology, so you don't need to reset the monitor when you change probes. For versatility, this unit also features an integrated differential pressure sensor so you can monitor the difference in pressure between two points.

• Light weight of 250g for ease of handling
• USB cable for simple data transfer
• Wide operating temperature range of -20°C to +50°C for use in demanding environments
• Memory of up to 7500 measurement protocols for ample data storage
• Broad differential pressure measuring range of -150 to +150hPa (hectopascal) for use in a wide variety of applications

• Commercial buildings
• Gas plants
• Industrial kitchens
• Laboratories

It has a broad temperature measuring range of -40°C to +150°C when using an NTC (negative temperature coefficient) sensor and -200°C to +1370°C when using a type K thermocouple sensor. This means it's a versatile choice for use in both hot and cold environments.
