BOD Direct Plus

Brilliant user experience

With the large and brilliant graphical display with detailed menu functionality, you can quickly and easily navigate through and measure the BOD. All in one device.

Individual monitoring and programming of samples

With LED lighting on the head of each sample bottle along with individual programming of the samples, you are always in control of how the BOD is developing for each individual sample.

Improved and comfortable data transfer with energy management

With two USB interfaces and one SD card interface, you now have multiple options of data transfer for further analysis. The BOD Direct Plus comes also with a mains power supply option (along with batteries) for permanent stability of power supply.
