Reliable real-time
data on CH4
GasPlug TECHNOLOGY | PATENTED DESIGN
Where is it found?
CH4 emissions also result from livestock and other agricultural practices, land use and solid waste landfills. Other natural sources include reduced, anoxic portions of wetlands and portions of ecosystems undergoing organic decomposition.
Why is it harmful?
High levels of CH4 can result in vision problems, memory loss, nausea, vomiting, and headache. In severe cases, there may be changes in breathing and heart rate, balance problems, numbness, and unconsciousness.
If exposure is large or continues for a longer period, it can kill. CH4 contributes to the formation of tropospheric ozone and particulate pollution.
CH4 cartridge
The Methane cartridge has a built-in non-dispersive infrared sensor (NDIR) ideal to measure concentrations for industrial applications with concentrations higher than 1,500 ppm.
Besides, it includes an automatic baseline calibration to maintain long-term stability with no effect of humidity, temperature, and pressure, which are corrected in the algorithm.

- Measurement range: concentration range measured by the sensor.
- Resolution: the smallest unit of measurement that can be indicated by the sensor.
- Operating temperature range: temperature interval at which the sensor is rated to operate safely and provide measurements.
- Operating RH range (Recommended RH range): humidity interval at which the sensor is rated to operate safely and provide measurements.
- Operating life: lifetime of the sensor at normal conditions.
- Guarantee range: limit covered by the guarantee.
- LOD (Limit Of Detection): measured at laboratory conditions at 20ºC and 50% RH. The limit of detection is the minimum concentration that can be detected as significantly different at zero gas concentration, based on the metric from the Technical Specification CEN/TS 17660-1:2022.
- Repeatability (measured at laboratory conditions at 20ºC and 50% RH): closeness of the agreement between the results of successive measurements of the same measure carried out under the same conditions of measurement, based on the metric from the Technical Specification CEN/TS 17660-1:2022.
- Response time: time needed by the sensor to reach 90% of the final stable value.
- Statistical metric: statistics obtained between the device hourly measurements and reference instruments for 1 to 8 months field test between -10 to +30ºC in different countries. (*) The expected error for PM10 is higher in the presence of coarse particles.
- Mean Absolute Error: it is the average mean absolute error (MAE) obtained between the device hourly measurements and reference instruments for 1 to 8 months of field test between -10 to +30ºC in different countries.
- Error: it is the error of the sensor at reading measurement or full scale.
- DQO-Typical U(exp): Data Quality Objective expressed as the Expanded Uncertainty in the Limit Value obtained between hourly measurements of the device and the reference instruments for 1 to 8 months field test between -10 to +30ºC in different countries, based on the metric from the European Air Quality Directive 2008/50/EC and from the Technical Specification CEN/TS 17660-1:2022. (*) The expected error for PM10 is higher in the presence of coarse particles.
- Typical intra-model variability: calculated as the standard deviation of the three sensor means in 1 to 8 months field test between -10 to +30ºC in different countries.
