RM31 is result of many years’ research from INNOKIE^Ⓡ. The portable and lightweight instrument is used for Oxygen measurement. It employs advanced digital signal processing (DSP) and temperature compensation technologies to accurately and rapidly measure oxygen level. RM31 is superiorly suitable for measuring H2, N2, Ar, C2H2, C2H4, C4H6 and even 100% oxygen content.

RM31 adopts electrochemical oxygen sensor. This type of sensor is similar with conventional galvanic oxygen sensor with lead anode. However, this unique sensor implements a weak acid electrolyte, which makes it obviously advantageous to conventional sensors. The measurement is not effected by CO2, CO and NOx.

The operational amplifier has very small temperature floating after even long term operation.The matched resistances have nearly the same rate

Precision technology of small signal processing is implemented to guarantee high linearity after signal amplified hundred times. It makes output signal reach high accuracy and linearity after adopting the technology of circuit and algorithm compensation. Neural networks based algorithm compensation is also employed to ensure the best output.

The sensor output usually floats and get contaminated in operation, making the measured result unreliable. RM31 adopts automatic adjusting reference to calibrate and compensate output, which makes the result stable, reliable and accurate.
