GE’s Druck PTX 1290 submersible pressure transmitter provides pressure and level measurement in wastewater lift stations. An all-titanium construction ensures resistance to the most corrosive and hazardous applications and the transmitter carries a five-year corrosion warranty. The transmitter is similar to the Druck 1830 line of submersible sensors, with the exception of a pressure port. Its flush Polytetrafluoroethylene-coated elastomeric diaphragm prevents buildup of grease and biosolids.

Bacteria detection system

The FDA has approved Whatman’s FTA Concentrator-PS: A portable two-stage paper filter that can detect bacteria in water supplies. The device essentially traps and preserves the organism’s DNA - pinpointing the source of the contaminant - which can then be tested to confirm and track the presence of any number of parasites. The filter can be used as a field test for Cryptosporidium, Giardia, Cyclosporia, and other parasites. The device can be stored at room temperature, and improves speed, collection and efficacy.

New fluorescence sensors from YSI detect pigments specific to blue-green algae (a.k.a. cyanobacteria). The sensors use the in vivo fluorometry (IVF) technique, which measures the fluorescence of accessory pigments unique to blue-green algae: phycocyanin or phycoerythrin. Because there is no special sample handling or processing required, IVF is ideal for profiling, moored, and real-time data collection using YSI multiparameter sondes.
