More chips for gas and vapour monitors
Dräger has added two more chips to its Chip Measurement System (CMS) for the water and waste industries. The new chips enable this portable gas and vapour monitoring unit to measure hydrogen sulphide and ammonia.
Requiring minimal user training, when plugged into the CMS analyser, the system
measures and evaluates concentrations of the substances and the chips provide
an immediate digital read-out without further need for evaluation.
Combining intelligent operation with straightforward user instructions, the
CMS features a back-lit, multi-lingual LCD display and menu driven user interface.
Supplied pre-configured for automatic operation, the analyser performs a self-check
on system start up and, as soon as the chip is inserted, carries out a chip
Incorporating a mass-flow regulated pumps, the CMS measures the movement of
concentration in relation to time, regardless of fluctuations in atmospheric pressure. This constant
mass flow capability, together with the sensitivity of the reagent system, enables
fast, accurate measurements to be made. Before carrying out a measurement, the
system allows the user to select the way in which data are stored.
A tone signal sounds at the end of each measurement cycle, and at this stage,
another measurement can be made or another chip selected. A wide variety of
chips are available for different applications.
Each chip carries a bar code which, when decoded, provides the parameters for
the measurement evaluation such as the gas type and measurement range. Able
to carry out 10 separate measurements, the chips have a 2-year lifespan.
For those applications where liquids may be present, a special float probe
can also be supplied. Protected against dust and spray water in accordance with
IP54, the CMS is intrinsically safe and resistant to eletromagnetic radiation.
