- This calibrator is a highly portable transfer standard for three pollutant gases without the need for a compressed cylinder of nitric oxide.
- Has an intuitive touch-screen interface and capability for remote operation (Modbus TCP/IP)
- Uses photolysis of oxygen in scrubbed ambient air to produce ozone
- Uses a patented process to photolyze nitrous oxide (N2O) to form nitric oxide
- N2O is provided by disposable 8 or 16 oz cartridges typically used for making whipped cream
- A surplus of NO is reacted with O3 to produce calibrated concentratons of NO2 (same method of producing NO2 as traditional GPT calibrators)
- Traceability to NIST is linked to 2B Tech’s O3 standard
