DELTAsmart flue gas analyzer

The DELTASMART MRU combustion gas analyzer is a professional instrument essential for heating specialists and thermal maintenance technicians. Compact, robust, and highly accurate, it measures the main combustion gases (O₂, CO, NO), as well as temperature, differential pressure, and draft of systems operating on gas, oil, wood, biomass, or solid fuels.

Designed for field use, this combustion gas analyzer combines reliability, speed, and ease of use. It is ideal for inspections, adjustments, and diagnostics of boilers, including condensing models.

A complete combustion gas analyzer for all your field operations

Advanced features for reliable and fast measurements

The DELTASMART MRU is equipped with three electrochemical cells (O₂, CO, NO), a digital manometer, a differential thermometer, and an ambient CO detector. It also performs calculations for CO₂, losses, combustion efficiency, excess air, and dew point. With 10 pre-programmed fuels and 2 customizable ones, it adapts to all types of installations.

Simplified replacement with MSM technology

The MSM (MRU Sensor Management) system allows autonomous and instant replacement of pre-calibrated measurement cells. No need for after-sales service: maintenance becomes simple, fast, and cost-effective.
