Tanabyte - Model 725 -Ozone Analyzer with Internal Zero/Span

The 725 is designed be be a low cost alternative to the 723 for ambient monitoring applications when an internal zero/span or multipoint cal check is needed.

Unlike the 723 aand 724, the 725 does not include a zero air pump, but relies on the photometer pump to draw air througn the scrubber and ozone generator when in calibration mode.

Installed in either the Portable or Dual Docking Station, the Model 725 is an ideal replacement for the Dasibi 1008.
