FEM-approved NO2 monitor with absorption of 405 nm light. The Model 405 nm also measures NO by conversion to NO2 using ozone.

The Model 106-L Ozone Monitor is designed for measurements of ozone concentrations ranging from low ppb levels up to 100 ppm (100,000 ppb). This highly accurate ozone monitor (1.5 ppb) has a low limit of detection (3.0 ppb for 10 second measurements) and is certified by the EPA as a FEM for monitoring for compliance with the US Clean Air Act: EQOA-0914-218.
EPA-certified Federal Equivalent Method (FEM) dual-beam UV absorption at 254 nm with two detection cells to improve precision, baseline stability, and response time. Lightweight with low power consumption and a quiet, long-life internal air pump. For research and monitoring applications where high precision and/or fast response are required.
Handheld EPA-certified ozone monitor capable of providing highly accurate/precise ozone measurements in a package that is unique to the ambient ozone monitoring market.
MCerts and TÜV Certified { EN 15267-4:2024 | EN 12619:2013 | QAL1 (EN 14181} the OneFID is a cutting-edge Heated Flame Ionization Detector (HFID) featuring a proprietary, patented injection system that allows for the simultaneous measurement of Total Hydrocarbons (THC), methane (CH₄), and non-methane hydrocarbons (NMHC) using a single detector. This innovative design simplifies system architecture, reduces operational complexity, and ensures exceptional measurement accuracy, long-term reliability, and full regulatory compliance for industrial emissions monitoring applications.
The PyxisGC BTEX is an innovative, reliable and versatile “carrier-gas free” chromatograph designed for monitoring of Benzene, Toluene, Ethylbenzene, and Xylenes in ambient air.
