SmartGAS Flow EVO PLUS

High-Performance NDIR Sensors for Process Measurement

The smartGAS Flow EVO PLUS series represents the next level of NDIR gas measurement technology, delivering outstanding precision, speed, and reliability for demanding process control applications. Building on the proven Flow EVO platform, the PLUS version offers significantly enhanced performance with extremely low noise, fast response times (T90 ≤ 3 seconds), and high readout frequency up to 10 Hz, enabling real-time, high-accuracy gas analysis even in dynamic processes.

These ready-to-use sensors combine low detection limits, minimal drift, and a wide operating temperature range with advanced features such as internal heating control (±0.5 K) to prevent condensation, digital RS232/RS485 interfaces, optional analogue output, and pressure compensation.

Available in both standard and heated versions (with optional case and thermal isolation), the Flow EVO PLUS series provides maximum flexibility for complex multi-gas measurement tasks while keeping maintenance and operating costs remarkably low.

Engineered for continuous operation in industrial environments, these compact, robust sensors deliver consistent, high-precision results across a broad range of gases, making them the ideal choice for professionals who demand the highest measurement quality without compromise.
