  • Water hardness is caused almost entirely by calcium and magnesium ions. Other di- and trivalent metals have a similar effect, but usually are not present in high enough concentration in potable waters to cause problems. Hardness increases soap consumption in laundries and causes scale in boilers. …

  • 5-in-1 test strips are great  for quick, on-site evaluations of water quality with reliable results on every test.  These mulit-parameter test strips test for five water quality measurements on 1 strip: Free Chlorine (0-10 mg/L) Total Chlorine (0-10 mg/L) Total Hardness (as…

  • For determination of Reactive (ortho) and Total Phosphorus (phosphate) by the Ascorbic Acid method, using TNTplus vials. Hach Methods 10209 (reactive) and 10210 (total). Low Range: 0.05-1.50 mg/L PO4-P (0.15-4.50 mg/L PO4). 25 tests/package. Reduce Errors with Bar-coded Vials No Reagent…

  • In addition to all of the test offered in Model BT-DT (2350600) this test kit provides testing capability for iron, silica, chlorine, nitrite, and total dissolved solids (TDS). The versatility and accuracy of this test kit will prove invaluable to boiler operators and chemical sales professionals. …

  • Alkalinity is caused by the presence of carbonates, bicarbonates, hydroxides, and other dissolved salts in water. Alkalinity control is important to food and beverage processors, boiler operators, and aquatic biologists. Model AL-AP single parameter alkalinity test kit has a range of 0.4-8 gpg…

  • A test kit for professionals, Model FF-2 allows measurement of 10 critical water parameters using accurate Digital Titrator titration and continuous color-disc colorimetry. Tests include Acidity M & Total (100-4000 mg/L as CaCO3), Alkalinity P&M (100-4000 mg/L as…

  • For determination of Reactive (ortho) and Total Phosphorus (phosphate) by the Ascorbic Acid method, using TNTplus vials. Hach Methods 10209 (reactive) and 10210 (total). High Range: 0.5-5.0 mg/L PO4-P (1.5-15.0 mg/L PO4). 25 tests/package Reduce Errors with Bar-coded Vials No Reagent…

  • Resulting from the anaerobic decomposition of organic matter, hydrogen sulfide is present in many water supplies. Sewage and industrial wastes are other sources of sulfide pollution. Highly toxic, this compound has a characteristic rotten egg odor, which can be detected long before harmful…

  • Phosphorus TNTplus® chemistry and your Hach spectrophotometer are engineered to simplify water analysis for accurate results, everytime. For determination of Reactive (ortho) Phosphorus (phosphate) by the Molybdovanadate method. Easy and safe handling No reagent blank necessary …

  • For determination of Ammonia Nitrogen by the Salicylate Method, using TNTplus vials. Hach Method 10205. Low Range: 1 - 12 mg/L NH3-N. 25 tests/package Reduce Errors with Bar-coded Vials No Reagent Blank Necessary Innovative Vial and Reagent Delivery Helpful package design

  • Phosphorus occurs in natural waters as one of the forms of phosphates: ortho- or reactive phosphate, meta- or poly- (condensed) phosphate, and organic phosphate. Phosphates enter water supplies from soil runoff, cleaning operations, water treatment, boiler blowdown, and sewage. Although…

  • Reagent for phenol distillation.

  • Color Disc/Stannous 100 tests

  • Test Kit, Nitrogen, Ammonia, mid-range, for freshwater. Color disc/Nessler reagent

  • Without aspirin, for use with hydrogen sulfide test. Contains 2 packages of 18 each for a total of 36.

  • Simply dip into a sample or hold under a liquid stream; for most products, in one minute or less, results are available to compare with the color chart included on the bottle's label.

  • Using the simple color disc method, this kit measures Iron (medium range: 0.1 - 4 mg/L) and contains reagent for 100 tests. Includes one reagent, two color discs, comparator box, two viewing tubes, instructions and carrying case Simple, low-cost color disc method is the most accurate…

  • For determination of Chemical Oxygen Demand (COD) by the Mercury-Free Reactor Digestion Method, using TNTplus™ vials. Hach Method 10236 Range: 25-1000 mg/L COD. Reduce Errors with Bar-coded Vials No Reagent Blank Necessary Innovative Vial and Reagent Delivery Helpful package design
