仪器简介：

The Model 408 Nitric Oxide Calibration Source is a portable source of nitric oxide that allows one to calibrate any nitric oxide monitor. The instrument scrubs NO from ambient air and produces either zero air or air having a mixing ratio of NO in the range 10-1,000 parts-per-billion by volume (ppbv). The desired NO concentration is chosen from the easy-to-use menu using a rotary select switch. The instrument can be programmed to output up to 10 individual NO step concentrations over a chosen time interval. The total output volumetric flow rate is 3.0 L/min, and the NO mixing ratio is controlled so as to be independent of ambient temperature, pressure and humidity.

You can attach the NO Calibration Source output directly to the inlet of any nitric oxide monitor (providing that its sampling rate is less than 3.0 L/min), with the excess flow vented through an external overflow tee. Besides portability, an important advantage of the Model NO Calibration Source is that it provides a known concentration of NO in ambient air containing the same level of humidity as the air sample to be measured.

The NO Calibration Source is factory calibrated against a NIST-traceable standard. However, the calibration parameters may be changed in the menu in case the user wants to recalibrate the NO Calibration Source against a separately maintained standard; i.e., the NO Calibration Source can be used as a transfer standard. The NO Calibration Source may be used, for example, for maintaining the calibration of a large number of NO monitors in the field relative to a highly stable laboratory standard. In this case, a huge advantage of the NO Calibration Source is its portability.
