The DK311 MultiLog ruggedPlus is a compact and extremely robust multi-signal data logger from the German brand Driesen + Kern. This logger is designed to measure and record a wide variety of signals under harsh conditions. Thanks to the connection for one external sensor, it can be used flexibly in industrial, scientific and environmental applications.

The DK311 supports various sensor types, including PT100/PT1000, thermistors, voltage (0–10V), current (0–20mA), pulse/frequency, digital humidity and temperature sensors, water detection and soil moisture sensors. The device operates reliably within a temperature range of –40°C to +90°C.

The shockproof POM housing and IP65 protection rating make the DK311 ideal for use in challenging environments. With a memory of 4 million readings, a replaceable lithium battery (up to 4 years lifespan) and a convenient USB interface, this logger offers a powerful and durable measurement system.
