Ozone Monitor: Model 202
 |
The Model 202 Ozone Monitor™ is designed to enable accurate and precise (±1.5 ppb) measurements of ozone ranging from a few ppb to 100,000 ppb (0-100 ppm) based on the well established technique of UV absorbance at 254 nm. The Ozone Monitor™ is light weight (2.1 kg.) and has a power consumption of only 4 watts. The Model 202 Ozone Monitor can be used in almost any application where much larger ozone monitors have been used in the past and in many environments where measurements using traditional ozone monitors are impossible.

Ozone Monitor: Model 205
|
The Model 205 Dual Beam Ozone Monitor™ was designed for even higher precision and faster response time than our popular Model 202. Data may be output as frequently as every 2 s, making it ideal for vertical profiling using balloons or aircraft measurements where high temporal resolution is required. For a given averaging time, the Model 205 has a higher precision (better than 1 ppb for 10 s averaging) and a more stable baseline than the Model 202. The Model 205 has all of the features of the Model 202 single beam instrument, including a real time clock; averaging times of 10 s, 1 min, 5 min and 1 h; an internal data logger; serial and analog data outputs; and a backup air pump to protect against data loss in the field.

Ozone Calibration Source: Model 306
|
The Model 306 Ozone Calibration Source™ is a highly portable ozone transfer standard that may used to calibrate any ozone monitor or sensor. Ozone is generated at any chosen concentration in the range 0-1000 ppb in ozone-scrubbed ambient air at a volumetric flow rate of 3 L/min. No external air source is requried. The instrument may be programmed to output a series of up to 10 ozone concentration steps with a chosen time interal. The Ozone Calibration Source™ is provided with a NIST-traceable calibration, and the menu allows the user to calibrate the output to their own reference instrument. This Ozone Cal Source™ is particularly useful for calibrating networks of ozone monitors in the field.

NO Monitor: Model 400
 |
The Model 400 Nitric Oxide Monitor™ measures NO from the low ppb level to 2000 ppb (2 ppm) using a recently patented measurement method based on a continuous titration of NO with ozone. Unlike the chemiluminescence method, the measurement is based on an absolute method, thereby elminating the need for frequent calibration. The NO Monitor is portable and has a relatively low power consumption, making it suitable for field use. When used in combination with the Model 401 NO2 Converter, the combined system can measure both NO and NOx. As in the chemiluminescence method, NO2 is obtained by the difference in NOx and NO measurements.

NO2 Converter: Model 401
 |
The Model 401 NO2 Converter™ is a portable, heated molybdenum converter for reducing NO2 to NO. When air is sampled through the NO2 Converter™, the Model 400 Nitric Oxide Monitor measures NOx (NO + NO2). As in chemiluminescence instruments, the NO2 concentration is obtained from the difference in the NOx and NO measurement. This approach to NO2 measurements has long been used in EPA-approved chemiluminescence instruments. The NO2 Converter™ also has an internal zeroing cartridge for periodic measurement of the instrument baseline. Periodic measurements of NO, NOx and the zero are programmable through the Model 400 NO Monitor™.

NO Calibration Source: Model 408
|
The Model 408 NO Calibration Source™ is a highly portable source of nitric oxide in the range 0-1000 ppb. The Model 408 may be used to calibrate any nitric oxide monitor, including those based on chemiluminescence. In addition to the calibration of instruments used for air monitoring, an important application is the calibration of nitric oxide breath analyzers such as the Aerocrine NIOX®; and NIOX MINO® used for dianosis and evaluation of asthma patients. The NO Cal Source produces nitric oxide in NO-scrubbed ambient air by photolsis of nitrous oxide provided by small N2O cartridges. The calibration gas is supplied at an output flow rate of 3 L/min. The instrument may be programmed to output a series of up to 10 ozone concentration steps with a chosen time interal.
