Carbon Monoxide Sensors: How Do They Differ and Why Does ...

· The CO/H2 null sensor measures both the CO and H2 gas concentrations separately, and then subtracts the H2 gas reading from the CO gas reading. The COSH sensor, otherwise known as CO/H2S, is commonly used to detect for CO. This sensor is a combination of a carbon monoxide sensor plus a hydrogen sulfide sensor, with both sensors being built into a single housing. This sensor …

What is a Gas Sensor? Construction, Types & Working of Gas ...

· Introduction to Gas Sensor. A gas sensor is a device which detects the presence or concentration of gases in the atmosphere. Based on the concentration of the gas the sensor produces a corresponding potential difference by changing the resistance of the material inside the sensor, which can be measured as output voltage. Based on this voltage value the type and concentration of the gas …

Kohlenstoffmonoxid – Wikipedia

Kohlenstoffmonoxid (fachsprachlich Kohlenstoffmonooxid, gebräuchlich Kohlenmonoxid) ist eine chemische Verbindung aus Kohlenstoff und Sauerstoff mit der Summenformel CO. Kohlenstoffmonoxid ist ein farb-, geruch- und geschmackloses sowie toxisches Gas. Es entsteht unter anderem bei der unvollständigen Verbrennung von kohlenstoffhaltigen Stoffen bei unzureichender Sauerstoffzufuhr.
