In this episode Shahriar explores the technology behind combustion gas analyzers. These instruments are capable of measuring the concentration of various gasses such as O2, CO, CO2, NO2, SO2, etc. The particular unit shown in this video (E-Instruments E1500) is capable of holding two sensors.

The end-of-life Oxygen sensor is replaced to bring the unit back to life. The teardown of the instrument as well as the faulty Oxygen sensor are presented along with Raman chemical analysis of the sensor electrolyte. The biproduct of a burning candle as well as a HotHands hand warmer are analyzed using the instrument.
