Siemens introduces the P334 Colorimeter chlorine analyzer calibration instrument : New product for the U.S. market, to help users comply with EPA Method 334.0


Chicago, Illinois, USA, The new P334 Colorimeter instrument provides a simple, reliable solution for calibrating on-line chlorine analyzers in compliance with U.S. EPA Method 334.0, published in November 2009. The hand-held Colorimeter includes: an easy to follow step-by-step procedure guide; the easiest to use National Institute of Standards and Technology (NIST) traceable standards; and a certificate of calibration from the factory so the instrument can be used immediately. Applicable to the U.S. market only, the Colorimeter is the latest addition to Siemens’ disinfection, analyzer and controller portfolio.

The Colorimeter set contains primary chlorine standards kit that consists of constant concentration liquid standards contained in double-ended ampoules and a bottle of pre-measured double distilled water. The primary standards do not require any dilution calculations, additional glassware, extra distilled water or special procedures. This reduces the time and complexity of preparing a primary chlorine standard, which helps ensure quick and accurate results. The ergonomic and waterproof design makes the Colorimeter ideal for portable or benchtop use. The extra large backlit display is easy to read in all light conditions, outdoors or indoors, ensuring an accurate recording of the readings.

A step-by-step procedure manual for using the on-line analyzer and Colorimeter has been written specifically to meet the objectives of the regulations. This manual is designed to ensure that the proper procedures are being followed and to prevent unnecessary work. It is also designed to instill confidence in the Methods as they pertain to the operations at the individual utility.
