Rapidox 2112 Multiplex

Product Information

Available with 5, 10 or 15 independent gas inlet ports that are fed to a single gas outlet using a system of electronically controlled solenoid valves, the Multiplex comes in two designs: a more basic flow-through design or a more complex bypass design (see schematics on page 2). The bypass design is more suitable for long-distance tubing lengths as the sample ports are all sampled continuously via a secondary pump. This dramatically reduces the delay before a stable reading is obtained, when changing from one channel to the next.

Using the bespoke Rapidox software supplied with the 2112, the Multiplex is intended for fully automatic stand-alone operation. However, there is also a manual override dial on the unit allowing the user to select an individual channel of interest.

The Multiplex software allows the user to program how long each sample line is sampled for before moving to the next. If a channel is not required then it can be de-selected in the software and it will be skipped during the measurement cycle. The software also synchronises with the Rapidox analyser so that the user can easily tell which channel is being sampled at any time. The channels can be renamed for ease of identification and during data-logging, they are identified by unique colour coding on the live time graph.

Due to the manual facility, the Multiplex can be used with any other gas sampling systems or gas process applications requiring multiple sample points.
