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.

AquaSensors recently introduced a digital drinking water turbidity measurement system based on the company’s patented DataStick technology. The system provides turbidity measurement for drinking water applications, with 0.001 NTU resolution. The system features a 135 ml chamber requiring a very small amount of Formazin to perform EPA mandated calibrations and a low flow rate to conserve water. The system requires only one square foot of mounting space.
Hach has introduced the HQd series of portable electrochemical meters and IntelliCAL probes with “plug and play” digital technology. A single instrument can take up to two simultaneous measurements of pH, conductivity, LDO®, and ORP. It’s the first instrument for field and laboratory use that does not require the user to predetermine parameters. Plus, users can buy any probes they need now, and add more later.
Level, pressure measurement
Pressure Systems, manufacturer of KPSI Level and Pressure Transducers, now offers a Windows Mobile-based derivative of its K-ware applications software to operate its waterMonitor submersible, datalogging level transducers with a handheld Pocket PC. K-ware Mobile provides much of the functionality of K-ware, designed for desktop or laptop PCs, with an intuitive graphical user interface (GUI) for simplicity.
LaMotte, manufacturer of water analysis equipment, has introduced tests for Total Nitrogen (0-25 mg/L), and low (0-3.5 mg/L) and high (0-100 mg/L) Total Phosphorus. The tests are performed by reacting tubes in a heater block to a specified temperature for 30 minutes. Reagents (included) are then added to the tubes and the concentrations are read by a colorimeter or spectrophotometer.
To improve process control and troubleshooting of activated sludge wastewater plants, Respirometry Plus has announced that the Arthur Bench Respirometer is now available for short term rental and that instruction in performing the company’s toxicity, treatability and organic load tests are included in the offer. The Arthur Respirometer simulates the biological activity taking place in a pilot plant, and allows an advanced look at what will happen later in the full scale plant.

Vehicle tracking device
TrackStickPro, available from Saelig, is a new movement logger that uses GPS technology to track vehicle travel and position, displaying routes and speeds when downloaded to a PC. The device can be supplied with cigarette lighter plug or direct-wired to the vehicle. A three foot USB cable is supplied for downloading the stored data.
The Data Dolphin 400 (DD-400) Data Monitor from Scientific Technologies Automation Products Group is now available with cellular, spread spectrum and WiFi wireless communication options, as well as a 4MB non-volatile flash memory. RS-232 communications come as standard on all units, with Ethernet and RS-485 wired communication options also available. The configuration and data delivery software is common across each available communication option.

GEOtivity offers access to NOAA real-time Doppler rainfall for analysis. Users can view live real-time rainfall over their city via a free account on the company’s website. Users can also create a virtual rain gauge and convert Doppler data to rainfall intensity. Data is logged every 10 minutes.
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.

The electromagnetic flowmeter is designed for use in the water and process control industries.
Blue-green algae sensors
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.
