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.
- 0-250 ppm measurement range with 1.0 ppb precision
- Dual beam for heightened precision and fast measurements
- 2-second measurement frequency (fastest available on the market)
- Approved by the EPA as a FEM: EQOA-0410-190
Overview
- Makes use of two detection cells to improve precision, baseline stability, and response time
- UV light intensity measurements Io (ozone-scrubbed air) and I (unscrubbed air) are made simultaneously
- Fastest UV-based ozone monitor on the market, while still retaining the small size, weight, and power requirements of our popular Model 202 Ozone Monitor
- Desirable for aircraft and balloon measurements where high spatial resolution is needed
- For 10-s averaging, a precision of 1.0 ppb is achieved. Alternatively, one can choose to average more points internally to obtain even better precision
- Flash card memory and a long-life, quiet internal air sampling pump are now standard on the instrument
- Rackmount configuration available as an optional upgrade
