Model 306OCS臭氧標定源是一種輕便的臭氧源，可用于標定任意的臭氧檢測儀。該儀器凈化從周圍空氣中獲得的臭氧，且可產生30到1000ppbv臭氧的混合氣體。總流量輸出是2.5升/分鐘。臭氧混合比是被控制的，不受周圍空氣溫度、壓力和濕度的影響。儀器根據NIST溯源的臭氧標準校準。

臭氧濃度范圍:       0ppbv 和30ppbv-1,000ppbv
改變臭氧輸出值的反應時間: ≤30秒到95%濃度變化
流量:               2.5L/min

• 可校準任何臭氧檢測儀。高度的便攜式傳輸標準尤其適合于臭氧檢測網絡的維護
• 測試臭氧對橡膠、塑料和油漆等材料的影響
• 研究臭氧對植物的影響，可通過OCS產生不同臭氧值。

  The 2B Technologies Model 306 Ozone Calibration Source™ is a portable source of ozone that allows you to calibrate any ozone monitor - not just those manufactured by 2B Tech.  The instrument scrubs ozone from ambient air and produces any mixing ratio of ozone in the range 30 to1,000 ppbv.  The desired ozone concentration is chosen from the easy-to-use menu using a rotary select switch.  The total output flow rate is 3.0 L/min volumetric, and the ozone mixing ratio is controlled so as to be independent of ambient temperature, pressure and humidity.  You can attach the Ozone Calibration Source (OCS™) output directly to the inlet of any ozone monitor; the excess flow is vented through an ozone scrubber internal to the OCS.  Although the instrument comes calibrated against a NIST-traceable ozone standard, the menu allows the user to change the calibration parameters of the ozone output if desired.  For example, if you maintain an ozone reference instrument in the lab, you can use the OCS as a transfer standard for calibrating ozone instruments in the field relative to your lab standard.

  The Ozone Cal Source™ is housed in the same small, rugged instrument case as the Model 202 and Model 205 Ozone Monitors™.

  Some applications of the Model 306 Ozone Calibration Source™ include:

• Calibration of ozone monitors in the field.  This highly portable transfer standard is especially useful for maintaining the calibrations of networks of ozone monitors.
   
• Testing of materials such as rubber, plastics and paint for effects of ozone exposure.
   
• Studies of the effect of ozone on plants where a calibrated source of ozone is required.
