The Kimo KP320 and KP321 are pressure differential data loggers for measuring underpressure, overpressure and filter monitoring in air handling systems. The differential pressure data logger has a range of 1000 or 10000 Pa and has a memory of 2 million measuring points. The KP320 can be read out with the free Kilog Lite PC software, but also communicates via Bluetooth with an Android, or Apple IOS device. For advanced reports, there is the full version of the Kilog PC software. The housing has a built-in magnet, with which the logger can easily be attached to a metal surface.
