The DK654 rugged-Visual from Driesen + Kern is a powerful and durable data logger for differential pressure measurements. The logger accurately records pressure differences with a standard measuring range of ±1000 Pa, while other ranges up to ±1 bar or 5 bar are available as options.
The built-in display provides direct readout of measured values, giving you real-time insight into pressure changes. Thanks to its rugged POM housing and IP65 protection rating, the DK654 is suitable for use in demanding environments.
The logger features a memory of 4 million measurements, a USB interface for fast data transfer, and a replaceable lithium battery with a lifespan of up to 4 years. In addition, all data remains stored even in the event of battery failure.
With the intuitive "Shaky Start" function, the logger can easily be activated by shaking it.
Optionally, up to three additional external signals can be connected, making the DK654 a particularly versatile solution for complex measurement situations.
