Kits de tests environnementaux

Pre-calibrated test tubes and labware give fast, accurate results in the classroom or in the lab.

The LaMotte ColorQ meter is a simple way to test low and high concentrations of chlorine.

COD vials are used to measure the chemical oxygen demand of influent and effluent of wastewater treatrement facilities. Requires a digestor block and photometer/spectrophotometer.

Using silver nitrate titrant, this kit provides fast, accurate detection of chloride.

The test kits for chlorine in water utilize a self-filling ampoule technology that reduces the user’s exposure to chemicals.

The New Dual Range QAC Test Strip takes care of ALL of your testing needs on ONE STRIP!

Keep it simple with these easy-to-use, individual water test strips

The ammonia test kits employing the well-established Nessler reagent to determine ammonia concentrations are applicable to drinking water, clean surface water, and good-quality nitrified wastewater effluent.

Utilizing the simple color disc method, this kit measures Nitrogen, Nitrate as NO3 and contains 50 tests.

The replacement reagents for the iron tester sold seperatly. These high-quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.

The NED method is widely used in the quantitative analysis of nitrite and nitrate in water samples. NED readily undergoes a diazonium coupling reaction in the presence of nitrite to give a strongly colored pink azo compound. The intensity of the color is directly proportional to the concentration of nitrite in the sample. Due to the significant intensity of the developed color even at very low nitrite/nitrate concentrations, lower detection limits and measurement ranges are possible vs. chromotropic acid kits. In addition, the nitrate measurement uses only zinc which is less toxic than cadmium, making handling and disposal safer.

Low dissolved oxygen levels in surface water systems usually indicate serious pollution

Kit provides measurement of ortho- (reactive) and meta- (condensed) phosphate (requires hot acid digestion).

Dissolved Oxygen in water test kits for environmental and drinking water applications (ppm range) employ the indigo carmine method. The reduced form of indigo carmine reacts with D.O. to form a blue product. The indigo carmine methodology is not subject to interferences from temperature, salinity, or dissolved gases such as sulfide, which plague users of D.O. meters.

Most natural waters range from pH 4 to pH 9, but commonly are above pH 7 because of carbonates and bicarbonates (alkalinity).

Easy way to test water for carbon dioxide concentration.
