Model 306OCS臭氧标定源是一种轻便的臭氧源，可用于标定任意的臭氧检测仪。该仪器净化从周围空气中获得的臭氧，且可产生30到1000ppbv臭氧的混合气体。总流量输出是2.5升/分钟。臭氧混合比是被控制的，不受周围空气温度、压力和湿度的影响。仪器根据NIST溯源的臭氧标准校准。

臭氧浓度范围:       0ppbv 和30ppbv-1,000ppbv
改变臭氧输出值的反应时间: ≤30秒到95%浓度变化
流量:               2.5L/min

• 可校准任何臭氧检测仪。高度的便携式传输标准尤其适合于臭氧检测网络的维护
• 测试臭氧对橡胶、塑料和油漆等材料的影响
• 研究臭氧对植物的影响，可通过OCS产生不同臭氧值。

  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.
