GO Systemelektronik

What GO Systemelektronik does

GO Systemelektronik GmbH is a privately held German industrial-instrumentation company founded in 1994 and headquartered in Kiel, Germany, controlled by the Schlumbohm family (Managing Partner Gunnar Schlumbohm and Managing Director Jonas Gordon Schlumbohm). The company designs, manufactures, and services modular measurement and control systems for continuous online water quality monitoring, with primary applications in drinking water treatment, municipal and industrial wastewater, environmental surveillance (e.g., airport de-icing runoff monitoring for Salzburg Airport), and adjacent sectors such as pulp and paper. Its core technology is UV/Vis spectroscopy combined with a modular hardware-and-software platform (BlueSense transducers, BlueBox controllers, ISA spectrometers, BlueTrace sensors, BlueMon online analyzers, and the BlueGate cloud service), which together can compute up to 99 water parameters from a single optical sensor and scale to roughly 300 sensors and actuators per BlueBox controller.

The product architecture is built around proprietary differentiators including an adjustable optical path length (0.5–20 mm) on the ISA spectrometer, an externally housed electronics design that enables field-serviceable maintenance, integrated automatic compressed air cleaning, and a Spectral Quality Index (SQI) for real-time calibration monitoring. The 2026 product wave adds the BlueBox R1 controller (with LTE/WIFI and up to four BlueConnect Plus plug-in cards) and the 'BlueBox RS' spectrometer system, alongside new BlueTrace Plus fluorescence oil-in-water and turbidity probes and a Smart Wiper System accessory. ATEX certification (Category 3 standard, Category 2 optional) and ISO 9001:2015 quality certification support industrial and explosive-atmosphere deployments.

GO Systemelektronik operates a hybrid go-to-market model combining direct sales in Germany with an international certified service partner and distributor network covering more than 20 countries across Europe, Latin America, Asia-Pacific, the Middle East, and Africa. Revenue comes from hardware sales (sensors, spectrometers, controllers, analyzers, accessories), professional service and remote-maintenance contracts, and a recurring BlueGate cloud subscription with remote access, automatic backup, and alarm notification. Pricing is quote-based, marketed through a website, LinkedIn presence, email/newsletter campaigns, webinars, and major trade shows (most prominently IFAT 2026 in Munich). Headcount is in the 11–50 SME band.
