Instrument performs reagent-free portable chlorine tests for potable and process water

Erlanger, KY (March 17, 2010) – Leading water test manufacturer Palintest has received US Environmental Proection Agency (USEPA) approval for its portable chlorine testing instrument, ChloroSense.  With a unique method for water analysis, ChloroSense utilizes electrochemical sensors instead of traditional chemical reagents to measure chlorine levels in potable and process water.

Palintest’s reagent-free chlorine test for potable and process water, ChloroSense, has received EPA approval.

The ChloroSense unit measures both free and total chlorine simultaneously, giving results in less than 60 seconds.  The free chlorine accuracy is similar to the standard method (DPD) over the normal 0-5 mg/l, however the new technology also works on an extended range of up to 10mg/l free chlorine.  Total chlorine test accuracy is similar to chemical based methods, and works on a range of up to 75mg/l.  By achieving the approval, the Chlorosense was found by the agency to be as accurate, precise and effective as the more traditional, technique-dependent chemical-based methods of chlorine measurement.

The ChloroSense is easy to use, and does not require the operator to have experience in chemical testing to achieve accurate results.  No chemical reagents, additional equipment or preparation are required.  Total and free chlorine levels are measured simultaneously and displayed in under a minute, along with the temperature of the sample, on the large back-lit LCD screen.  All test information is stored in the unit’s memory, which can hold up to 500 sets of results.  A USB port allows easy connection to a PC for convenient downloading.  The compact, battery-powered unit is waterproof to an IP67 rating, and with a weight under three pounds, it is perfectly suited for testing in the field.

The Chlorosense testing device from Palintest Ltd. makes use of a completely new methodology for water analysis, utilising electrochemical sensors instead of traditional chemical reagents to measure chlorine levels in potable and process water. The portable, battery-powered device has now been approved by the U.S. Environmental Protection Agency (USEPA), following an expedited approval process (ref: 74 FR 57908, pub. Nov 10, 2009).

Chlorosense Digital Portable Chlorine Tester from Palintest Ltd Gains EPA Approval

The expedited approval process for drinking water analytical methods exists in order to allow the water industry more timely access to new testing. As the US EPA website (www.epa.gov) states: “A comparison of the new alternative method to the approved method(s) must show the new method to be equally effective in determining the concentration of the contaminant.” In achieving the approval, the Chlorosense was found by the agency to be at least as accurate, precise and effective as more traditional, technique-dependent chemical-based methods of chlorine measurement.

The ChloroSense unit measures both free and total chlorine simultaneously, giving results in less than 60 seconds. The free chlorine accuracy is similar to the standard method (DPD) over the normal 0-5 mg/l, however the new technology also works on an extended range of up to 10mg/l free chlorine. Total chlorine test accuracy is similar to chemical based methods, and works on a range of up to 75mg/l.

The major benefit of the ChloroSense compared to chemical reagent-based testing is its ease of use. An operator does not need to have experience in chemical testing to use the device, and only needs the Chlorosense unit, a disposable sensor and the water sample to be tested. No chemical reagents, additional equipment or preparation are required. Total and free chlorine levels are measured simultaneously and displayed in under a minute, along with the temperature of the sample, on the large back-lit LCD screen. All the test information is also stored in the unit’s memory, which can hold up to 500 sets of results. A USB port allows easy connection to a PC for simple, convenient downloading. The unit is compact, robust, and waterproof to an IP67 rating; with a handy carrying case, and weighing just 1kg, it is perfectly suited for testing in the field.

The product is simple to use and comes complete with instructions that enable users of any skill level to test chlorine levels and obtain consistent, repeatable results. Now with US EPA approval, the ChloroSense effectively combines excellent accuracy with previously unobtainable convenience and ease of use.

The new Chlorometer is very easy to use, with just 4 intuitive buttons and a menu that uses universal symbols instead of individual languages on its LCD display screen. While its small size (150 x 65 x 40mm) and light weight (200g) make the unit ideal for in-field and on-site testing, its accuracy (± 0.02 @ 1 mg/l) makes it suitable for bench use in both laboratories and treatment plants. Test ranges are 0.01-5.0 mg/l for Free and Total Chlorine levels, and 1-250 mg/l for Chlorine HR concentrations.

With an IP67 rating, the instrument is robust and waterproof, and can be supplied in either a hard or soft carry-case that also holds a store of reagents and test tubes. It uses only 2 AA batteries, giving around 5,000 readings thanks to its low power operation and auto switch-off setting when not in use. The zero reading is held in memory between uses, or can be reset for each test, while the new narrow band wavelength filters provide unparalleled wavelength accuracy for a handheld monitor.
