A suitable Calibration Gas Test Kit and a bottle of the
appropriate test gas.
Where the sensor accessories are not fitted, a Sample
Flow Housing will be required for accurate sensor
calibration.
Purpose built gassing equipment is available on
request from Zellweger Analytics Limited.

sensors are better left factory calibrated and only an
approximate calibration check made.
If applying H
