Other Gases |
Contact us with specific requirements for gas and concentration |
- Other specific concentrations available on request
- Accuracy < 0.5 ppm is unspecified (for applications that require accurate measurement < 0.5 ppm use low or ultra-low sensor heads)
- Non Methane Hydrocarbon sensor (lower sensitivity to alcohols & esters)
- Calibrated against Isobutylene. Other specific VOC calibrations are available on request
- D= diffusion, F = fan, P= pump
