OxyTrans M | Portable Dissolved Oxygen (DO) Meter & Data Logger
The Centec OXYTRANS M is a portable optical oxygen meter and data logger designed for high-precision measurement of dissolved oxygen in liquids and gases. Based on quenched optical luminescence technology, the OXYTRANS M delivers exceptional sensitivity and stability without the electrolytes, membranes, or routine recalibration of traditional electrochemical sensors.
With measurement ranges from 1 ppb to 35 ppm in liquids and 0–50 % in gases, plus a fast t90 response under 10 seconds, the OXYTRANS M suits brewery, beverage, food, pharmaceutical, and power plant applications. Integrated data logging records up to 5,000 measurements with adjustable 5–600 second intervals, downloadable via USB. Housed in a rugged IP65 aluminium enclosure and weighing just 1.65 kg, it’s a reliable handheld instrument for production, QC, and maintenance diagnostics.
