The most highly integrated and smallest sized nitrogen concentration analysis product on the market

Product Description
The M - 400 Nitrogen Analysis Module. It stands as the most highly integrated and smallest - sized nitrogen concentration analysis product on the market currently. Employing a zirconia oxygen sensor as the measuring unit, it undergoes high - quality circuit processing for precise amplification, filtering, acquisition, and analytical calculation of the sensor signals. This enables it to derive the oxygen concentration value in the mixed gas, from which the nitrogen concentration value is inferred. It provides both a 4 - 20mA analog signal and an RS485 digital signal, facilitating communication between this device and other equipment.
Product Features
Compact and Exquisite: It is currently the smallest oxygen analysis product on the market, with the sensor built - in.
High - Precision Zirconia Sensor: Utilizes a zirconia oxygen sensor, ensuring accurate measurement, fast response, and long service life.
Wide Power Supply Range: Operates within a voltage range of 18 - 24VDC, equipped with internal protections against overvoltage, static electricity, reverse connection, and overcurrent.
Advanced Pressure Compensation: Capable of eliminating the impact of altitude changes on measurement accuracy.
Excellent Analog Output: The 4 - 20mA analog current output features remarkable precision and stability, with an error of no more than 16uA.
Integrated Communication Module: Internally integrates an RS485 communication module for communication with computers, PLCs, and other devices.
