The free EuroSoft® connect App allows to transmit measured values to iOS and Android smartphones or tablets via QR code or Bluetooth®.
The BLUELYZER® C1 is built for professionals who value accuracy, simplicity, and reliability. It delivers precise measurement and analysis for the adjustment, maintenance, and inspection of small to medium-sized heating systems.
Beyond flue gas analysis, the BLUELYZER® C1 also measures differential pressures and temperatures, enabling quick determination of flow and return values. Integrated CO ambient monitoring adds an extra layer of safety with two freely adjustable alarm thresholds.
Seamless data transfer to the EuroSoft® connect app enables efficient, professional documentation. Customizable measurement programs and parameters provide maximum flexibility in everyday workflows, making the instrument adaptable to each user’s needs.
