The Problem Check test package analyzes water for 20 of the most common nuisance contaminants. Developed to uncover aesthetic problems, especially with iron, this test includes total, dissolved and iron bacteria. Additional contaminants tested include manganese, hardness, sulfate, tannins and potassium as well as other contaminants essential to determining treatment options.
The AND1000 fluorimeter is a new technology that uses DNA to detect metals in water in 30 seconds. The handheld device tests drinking water, environmental water and industrial water supplies. It uses an extremely sensitive measurement technique to determine the toxicity levels of heavy metal contamination to low parts-per-billion levels.
HQd meters and IntelliCAL probes are customized electrochemistry solutions for water quality testing that take the guesswork out of measurements. They offer lab personnel simple, intuitive operation, with a large, bright backlit meter display that is easy to read. The series offers probes for pH, DO, conductivity and ORP, as well as a line of ISE probes for ammonium, ammonia, chloride, fluoride, nitrate and sodium.
HQd series meters and IntelliCAL probes are specifically designed for the demanding environment of a wastewater treatment plant. Both the rugged IP-67-rated portable meters and the bench top meters deliver accurate measurement of influent, effluent and process streams. They offer plant operators and lab personnel simple, intuitive operation – calibration and measurements can be easily performed right out of the box. The large, bright backlit displays are easy to read at night and during the day.
HQd series meters and the IntelliCAL LBOD probe are specifically designed to simplify BOD testing and deliver better results. Lab personnel appreciate the simple, intuitive operation while working on a large, bright backlit meter display that is easy to read.
The DR6000 advanced lab spectrophotometer offers high-speed wavelength scanning across the UV and visible spectrum, and comes with more than 250 pre-programmed methods that include the most common testing methods used today. With optional accessories allowing for high-volume testing via a carousel sample changer and increased accuracy with a sample delivery system that eliminates optical difference errors, this instrument ensures readiness to handle wide-ranging water testing needs.
Approved method for global bottled water safety
3M Food Safety announced May 21 that its Petrifilm Aqua Coliform Count Plate has received NF validation from France-based Assn. Francaise de Normalisation (AFNOR) for its ability to detect and enumerate colonies of E. coli and coliform bacteria in bottled water samples.
When considering reverse osmosis (RO) for water treatment, there are several things that should be taken into account. One of the most important things to consider is the quality of the water to be treated. RO is widely used to remove harmful inorganic contaminants; however, due to the limitations and higher operating cost, pretreatment of the water may be necessary. For example, hardness minerals are common in groundwater, and at high levels, pretreating with a softener is often recommended.
The Complete RO Screen was developed with input from membrane manufacturers and treatment professionals. This package tests for most factors that can reduce the life of an RO membrane. Due to the nature of RO produced water, the testing was designed to provide lower detection levels. This test package is also beneficial for other applications that require pure water. New and improved compact packaging will reduce shipping costs.
