What Duotec A/S does
Duotec A/S is a Danish private limited company (Anpartsselskab) established in 1983, specializing in gas detection and measurement instrumentation. The company operates as a distributor and authorized service center representing more than eleven international manufacturers, including Honeywell/BW, Bieler+Lang, WatchGas, ION Science, Edinburgh Sensors, MRU, Bedfont, LogiCO2, Sensitron, Signal Group, and GASTEC. It serves customers across Denmark and Sweden in wastewater treatment, energy and heat supply, chemicals and laboratories, biogas production, oil and gas, and healthcare. The portfolio spans portable multigas detectors, single-gas detectors, VOC/PID detectors, biogas analyzers, fixed gas detection systems, and control units, built on NDIR, electrochemical, catalytic, and photoionization (PID) sensor technologies, with ATEX-certified products and SIL-1 certification held at the company level.
The company supports customers through multiple service channels: an in-house repair facility, mobile workshops providing on-site service, online ordering, and direct contact via telephone, email, and a web form. Distribution and service delivery are combined under a single authorized-service-center model, with calibration and repair offered across the full portfolio. Active engagement has expanded into LinkedIn as a digital marketing channel.
The business model rests on three revenue streams: (1) product sales of gas detection instruments, (2) service and repair, including calibration, and (3) equipment rental. The company employs approximately 10 staff and is in the process of relocating its headquarters to Herlev, suggesting a capital investment in operational capacity.
