6. OPTIONS
Following are descriptions of options available for the M465L.
6.1. Stream Selector (3 or 6 Stream)
This option allows the M465 to measure ozone at up to six different sampling points by using an
internal stream selector. 3 or 6 channel stream selectors are available. This option includes
digital outputs for HI and HI-HI alarms and a channel ID for each channel in the stream selector.
6.2. Disposable Sample Inlet Filters
This option consists of 50 disposable filters for installation at the inlet end of all sample lines.
6.3. Rack Mount Slides
Rack mount slides can be attached to the sides of the instrument, allowing it to slide completely
out of a RETMA rack, facilitating maintenance activities.
6.4. Electronic Flowmeter
The M465 can be fitted with an internal electronic flowmeter that enables the instrument to
display the flow digitally on the front panel and provides a Pneumatic Error if the flow is outside
its normal limits.
6.5. Sample Conditioner
For humid environments where there is risk of water condensation in the sample lines, this
option serves to filter out liquid and particulates and includes a permeation gas dryer as well. For
details, see “Sample Conditioner” in Section 4.1.1.2.
6.6. Permeation Gas Dryer
This option removes water vapor from the sample stream in environments where humidity is a
concern but where condensation is not a factor. For details, see “Permeation Gas Dryer” in
Section 4.1.1.2.
