HACH Hardness (Total) Test Kit, Model 5-B, Drop Count Titration, 1-30 gpg, 100 tests: Product #: 145300

• Trust the original Hach test kit!
• Simple drop-count titration measures hardness as CaCO₃ (1 gpg = 17.1 mg/L)

About water hardness:
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.

HACH 2100N Laboratory Turbidimeter, 230 Vac

Product #: 4700002

USEPA-COMPLIANT 2100N Laboratory Turbidimeter

Model 2100N Laboratory Turbidimeters measure turbidity in either ratio or non-ratio mode. Light from a tungsten-filament lamp is focused and passed through the sample. The 90-degree scatter detector receives light scattered by particles. Transmitted and forward scatter detectors receive light that passes through the sample.

Ratio and no-ratio turbidity measurement modes are selected using the ratio key located on the instrument keyboard. With ratio toggled off, turbidity is measured using only the single 90-degree detector. Benefits of the ratio mode include long-term calibration stability, wide measurement range with excellent linearity, and the ability to measure turbidity in the presence of color.

Product #: 4700102

USEPA-COMPLIANT 2100AN Laboratory Turbidimeter

Model 2100AN Laboratory Turbidimeters measure turbidity in either ratio or non-ratio mode. Light from a tungsten-filament lamp is focused and passed through the sample. The 90-degree scatter detector receives light scattered by particles. Transmitted and forward scatter detectors receive light that passes through the sample. A back scatter detector in the 2100AN Model (shown here) measures light scattered back toward the light source.

Ratio and no-ratio turbidity measurement modes are selected using the ratio key located on the instrument keyboard. With ratio toggled off, turbidity is measured using only the single 90-degree detector. Benefits of the ratio mode include long-term calibration stability, wide measurement range with excellent linearity, and the ability to measure turbidity in the presence of color.

HACH Arsenic Test Kit, 0-500 ppb, 100 tests

• No lab analysis needed - detect arsenic levels in the field to comply with the new EPA arsenic rule
• Reliable test strip method recovers 100% of inorganic arsenic in water samples

About Arsenic:
Arsenic is an element that occurs naturally in the earth's crust. The weathering of rocks and erosion can deposit arsenic in water bodies. Exposure to arsenic at high levels poses serious health effects as it is a known human carcinogen. Hach's Arsenic Test Kits can measure below 10 parts per billion of arsenic.

Parameter	Range	Steps (ppb)	Number of Tests
Arsenic	0-500 ppb	0, 10, 30, 50, 70, 300, 500 ppb	100
(Low Range)

Test Kit includes:

• Reagents for 100 tests
• Reaction vessel
• Test strips
• Comparison chart
• Rugged carrying case

Hach currently offers two arsenic test kits. The two kits differ in range, complexity, price, and performance:

Our Low Range Kit (Cat. # 2800000) has a range up to 500 ppb and is best for samples containing sulfide or arsenic-iron particles. It has excellent recovery of As⁺⁵ (100%) and can measure organic arsenic with optional steps.

The EZ Arsenic Kit (Cat. # 2822800) has a range up to 4000 ppb, takes fewer steps, and is more economical. However, the high-range kit recovers only 90% of inorganic As⁺⁵, and has no option for measuring organic arsenic.

HACH Chlorine (Free & Total) Test Kit, Model CN-66, Color Disc, 0.1-3.5 mg/L, 100 tests

Product #: 223101

Free & Total Chlorine Test Kit, Model CN-66 with Color Disc Method

• Quickly and accurately measure free and total chlorine levels in the field or in the lab
• Many Hach chlorine tests have been accepted by the U.S. EPA for reporting purposes. Verify acceptance with your local regulatory agency.

Uses powder DPD reagent that reacts with chlorine more quickly than tablet-form DPD, giving more accurate results. Powder DPD also has a considerable advantage over orthotolidine, a hazardous substance sometimes used as a chlorine test reagent.

Chlorine Test Kits are manufactured by Hach to ensure compliance with stringent quality control standards.

HACH Hardness (Total) Test Kit, Model HA-71A, Drop Count Titration, Dual Range, 100 tests: Product #: 145201

Hardness:

• Water hardness is caused almost entirely by calcium and magnesium ion. 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.
• Simply count the number of drops required to change the solution color to determine hardness concentration.

HACH Phosphorus, Orthophosphate (reactive) Test Kit, Model PO-19, Color Disc, 100 tests: Product #: 224800

Phosphate:

• 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 necessary for biological growth, too much phosphate causes excessive growth of aquatic plants and eutrophication. Industrial control includes maintenance of minimum levels in boilers and in cleaning operations.
