Coagulant charge analyzer
The Coagulant Charge Analyzer (CCA 3100), available from Chemtrac, determines the optimum coagulant dose in five minutes or less. Operators can adapt quicker to sudden quality changes in raw water than with conventional jar test. The analyzer also enables operators to compare, verify strengths, and "Q.C." incoming shipments of coagulants. The analyzer is simple to use and ensures reproducible results.

TraceDetect has released SafeGuard(tm), an automated trace metals analyzer that simplifies the measurement of arsenic and other metals in water. The new analyzer will measure total arsenic down to 2 ppb, without requiring a chemist to operate the instrument and interpret results. The system is the first automated analyzer with the accuracy required to meet the 2006 EPA arsenic limit for drinking water. It can display test results on site in 20 minutes.
CHEMetrics has released its new V-2000 Multi-Analyte Photometer. Lightweight and field portable, this microprocessor-based LED photometer features preprogrammed methods to measure 13 mm, 16 mm, or 1 in. cells in either concentration, transmittance, or absorbance modes. With RS-232 output, it can log 100 data points and download them to a printer or computer. Using the company's self-filling premeasured Vacu-vial(r) reagent ampoules, the photometer provides water quality tests for 30 important analytes including ammonia, chlorine, nitrate, phosphate, phenols, and COD.
Global Water's Flow Sampling System is a water monitoring package that includes a lightweight composite water sampler, an open channel flow monitor with dual displays and outputs, and a data recorder that is both Windows and Palm Pilot compatible. The compact package is portable for field installation and customizable to meet specific monitoring needs. The flow-proportional water sampler is enclosed in a rainproof, lockable carrying container.

Patented Easygel agar replacement simplifies testing for coliforms and E. coli in environmental samples, drinking water or treated wastewater. Available from Forestry Suppliers, Easygel is a pectin-gel testing method sold as a sterile 2-part test unit consisting of a patented liquid medium and a pretreated petri dish. When the liquid medium is poured into the petri dish, ions diffuse from the pretreated layer into the liquid causing it to gel in about 40 minutes.
