PRINTING HISTORY This manual covers the Model 408 NO Calibration Source used as 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 20-1,000 parts-per-billion by volume (ppb).
WARRANTY STATEMENT 2B Technologies warrants its products against defects in materials and workmanship. 2B Technologies will, at its option, repair or replace products which prove to be defective. The warranty set forth is exclusive and no other warranty, whether written or oral, is expressed or implied.
