NET has developed the new MAK series, i.e. MEMS Analogue Katharometer.

MAK is a thermal conductivity sensor, or KATHAROMETER, which measures the concentration of gases whose thermal conductivity differs significantly from that of the reference gas, usually air, in a range from 0 to 100% by volume.

🔹 This device measures the variation in the air's ability to conduct heat: a parameter that changes significantly in the presence of hydrogen, the gas with the highest thermal conductivity among all known gases.

🔹 MAK thermal sensors cover the entire detection spectrum, operating effectively from ppm levels up to 100% by volume, thanks to their ability to function without oxygen.

🔹 Thermal conductivity sensors offer superior long-term stability and a longer operational lifetime compared to sensors based on chemical reactions, which gradually decay over time.

🔹 It is designed to operate over a wide temperature range, from -40 °C to +60 °C, with automatic compensation of environmental conditions (temperature, humidity, and pressure) allowing its use in various applications.

🔹 Superior resistance to mechanical shocks compared to catalytic sensors or traditional thermal conductivity sensors, another advantage of the MEMS technology with integrated membrane adopted by NET.

🔹 It is immune to poisoning, as the common poisons/inhibitors cannot stick to the active part of the sensor.

🔹 Another key factor is the fast sensor response (< 1.4 s), which is only limited by the time required for variations in the MEMS element’s resistance.
