Kits de tests environnementaux

This chemical test kit measures carbon dioxide by titration with sodium hydroxide. It is supplied complete with all of the reagents and equipment necessary to perform approximately 100 tests.

This chemical test kit for the determination of six parameters commonly monitored for aquaculture testing: alkalinity, carbon dioxide, hardness, dissolved oxygen, pH, and salinity. This kit is equipped with all the necessary reagents and equipment to perform over 100 tests for each parameter. pH is obtained with Hanna's pH tester, which guarantees greater accuracy and a longer life than traditional litmus paper.

This chemical test kit uses an adaptation of the Nessler method to measure ammonia in fresh water. The test kit is supplied complete with all of the reagents and equipment necessary to perform approximately 25 tests.

This chemical test kit that uses the phenanthroline method to measure total iron in the medium range. This chemical test kit is supplied complete with all of the reagents and equipment necessary to perform approximately 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.

Dual-purpose test kit for measuring nitrate levels in soil and irrigation water to study nutrient cycling and agricultural impact.

Colorimetric test kit for measuring nitrate levels in water, ideal for studying nutrient pollution and environmental impact.

The test kits utilize CHEMetrics Titrets® ampoules. Titrets ampoules use a reverse titration technique to measure analyte concentration levels (titrant volume inside the ampoule is fixed while the sample volume is varied).

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.

Titrets® test kits use reverse titration to quantify concentrations in aqueous samples

Ceric sulfate is the titrant and ferroin is the end point indicator. The method is free from glycol interference in samples that contain up to 75% glycol, making it particularly applicable to systems that contain nitrite corrosion inhibitors. Results are expressed as ppm (mg/L) NaNO2.

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

CHEMetrics’ Manganese water test kits employ the periodate chemistry that measures soluble manganese compounds but does not differentiate the various valence states.
