5.5 Expandability to 4 sensors
In the Chemist 400 instruments range, two are the versions which can be expanded:
The upgrading of the number of sensors can be easily done by the user by performing the following directions:
- Both the expandable instruments are arranged in a way to accept one or two additional sensors in positions S3
and S4.
- Identify, with the help of paragraph 5.2 'Sensor types and relevant positioning' the sensor(s) which must be
added to the existing configuration (Seitron delivers all FLEX-series sensors already pre-calibrated and ready
to use).
- To install the new sensors follow all the steps described in the paragraph 'MAINTENANCE' under 'gas sensors
replacement'.
