WATERTRAP* Probe (Part No. CR013EA)
The WATERTRAP probe is an accessory used in conjunction with the CENTURY ® OVA or
TVA-1000 which protects the analyzer from damage or contamination due to ingestion of
liquids. It can be installed in place of the standard close area sampler. Use of the WATER-
TRAP probe prevents the passage of water into the analyzer sampling system, protecting your
instrument from costly damage.
WATERTRAP Parts
The WATERTRAP probe (Part No. CR013EA) is an assembly comprised of two molded Delrin
body halves, the sampling end with a 316 stainless steel probe tip. Internal to this assembly
are two replaceable parts – a membrane/O-ring assembly and membrane support.
The Membrane/O-ring Assembly (P/N CR013ED) consists of a thin, hydrophobic membrane
(of proprietary material) and a Viton O-ring. Both the membrane and O-ring are combined
into a single assembly. The membrane is what actually prevents the passage of liquids
through the probe.
The Membrane Support (P/N CR013EC) is a hard sintered plastic disk made of PVDF, used
to hold the membrane in place.
