SMART-OO Optical oxygen analyzer is cost-effective and suitable for stable and continuous measurement of the percentage oxygen content of most gases. This principle is very robust. It shows virtually no interferences to other gases (except Cl2 and NO2), has a very low drift, and the sensor is fully solid-state. It does not deplete over time, unlike galvanic oxygen sensors with their limited shelf life. Optics and electronics are hermetically sealed from the measured gas. For typical indoor environmental conditions, a 10-year operating life is expected.

SMART-OXZ Oxygen Analyzer uses a unique reference built-in zirconia technology, higher accuracy and repeatability oxygen measurement, no need to provide standard air and calibration. The sensor life is typically 5 years or more and is typically used for oxygen content measurements at ppb, ppm, air concentration (20.64%). The analyzer employs a Type B (Pt–Rh) thermocouple to measure the absolute temperature of the zirconia probe, which significantly enhances measurement stability, accuracy, and long-term reliability under high-temperature conditions.

SMART-EC Galvanic Electrochemical trace/percent Oxygen Analyzer uses a Micro-Fuel Cell sensor, which can measure trace oxygen (ppm level) or percentage oxygen (% level), achieving high-precision and high-repeatability oxygen measurement. It is suitable for a variety of industrial process gas monitoring.

SMART-OXM Paramagnetic Oxygen Analyzer uses high-stability paramagnetic oxygen technology to achieve high-precision and high-repeatability oxygen measurement.
