Eco Physics CLD 780 TR
Tropospheric Research Gas Analyzer
| RANGE | 5 ppb – 500 ppb |
| Minimum Detectable Concentration | 3 ppt |
| PARAMETERS | NO / Nox |
The NO analyzer for scientific research of the free troposphere. Specially designed to rapidly detect very low NO/NOX concentrations in the range of parts per trillion, the CLD 780 TR is a tailor-made solution for aircraft and vertical flux measurements.
