Required calibration
parameters are large
(>



15% slope) when

calibrated using a
reliable ozone
instrument.

Flow path is contaminated.

Replace the absorption cell,
or return instrument to 2B
Technologies for cleaning or
replacement of the
absorption cell.

2B  Technologies  offers  reasonably  priced  customer  service  for  instrument  repairs.
The calibration service includes cleaning of the entire flow path with methanol, testing
of  all  components  for  proper  function  and  calibration  against  an  IOA-traceable
standard.  The best way to contact us for service is to log a customer service ticket at
