A five-element instrument from Sherwood Scientific has been launched for applications such as the analysis of sodium in drinking water and wastewater. The Model 360 is a single channel unit built around the very same mixing chamber, burner stem and burner head found in Sherwood's Model 410. It also incorporates automatic flame optimisation technology from the dual channel 420 series.
The design places all the controls, the pressure gauge, air regulator and sample introduction on the front of the instrument.
The sample work area features a spill containment tray which is said to be easy to remove and clean.
LEDs on the front panel indicate the filter selected — sodium, potassium, lithium, calcium or barium — and the flame status. A display 'hold' button ensures that readings are not lost before they have been recorded and the peak picker function presents unambiguous results.
The instrument is sized at 20 x 30 cm and a mixing chamber, burner head and burner stem come apart for cleaning without tools and the five-element filter stick is simple to remove. Electronics and pneumatics are housed in separate 'pods' which are easily detached from the main instrument chassis.
Jon Copsey, Sherwood Scientific's marketing manager, said: "The 360 responds to the current demand for five filters as standard in a low-cost instrument. However, incorporating Sherwood's world-renowned stable flame technology eliminates the need for constant recalibration during use, while providing the levels of precision, reliability and ease of use typically associated with a much higher cost unit."

Asheville to roll out smart metering water program
The City of Asheville, North Carolina has selected Mueller Systems to help it improve the efficiency and service of its water operations through the implementation of a comprehensive, smart metering water program.
Mueller Systems will provide Asheville with a turnkey solution, including installation services, project management, Automated Meter Reading (AMR) modules and water meters for 52,000 connections.
Brandon Buckner, superintendent of Meter Services for Asheville, said: "With our increasing awareness of the need to better manage our priceless water resources, it is even more important that we, as a conscientious municipality, accurately account for every drop of water that is treated and distributed through our system."
Mueller Systems' AMR system enables utilities to improve customer service while simultaneously increasing operational efficiencies.
According to the company, the Hot Rod™ transmitters enhance utilities' ability to capture drive-by meter readings, and the open architecture of the AMR system component allows the solution to work with other brands of encoded meters that utilities may already have installed. The Hot Rod AMR system also includes a data logging feature that allows for six months' worth of hourly usage data stored at the meter, with graphically displayed alarms to enable utilities to quickly respond to customer questions and proactively approach customers about possible leaks or tampering.
The system also provides a seamless migration path from AMR to the Mi.Net™ Mueller Infrastructure Network for Utilities Advanced Metering Infrastructure (AMI) system as needs and service areas grow.
The Mi.Net System is a communications network that fully automates the meter-reading-to-billing process, linking meters, distribution sites and control devices in a single, highly efficient data network.
Topography challenges of Asheville were said to place a requirement on transmission speed.
Jim Hendricks, area manager for Mueller Systems, said: "Asheville needed an AMR system that was fast, and our two-second transmission —- the fastest in the industry -- exceeded this requirement."
