Iron Water Test Kit with Extended Range for Field and Lab Use
Iron in water causes red, yellow, and brown staining on fixtures, metallic taste, and buildup that damages equipment. The Hach iron test kit Model IR-18B is an iron color disc test kit that measures dissolved iron from 0.25 to 7 mg/L using the 1,10-phenanthroline method. This iron water test kit includes reagents for 100 tests and works without batteries, calibration, or a power source.
Key Features and Benefits
- 0.25 to 7 mg/L measurement range spans well water, municipal systems, industrial process water, and wastewater. This Hach iron test kit reads from just below the 0.3 mg/L drinking water guideline to high-iron sources without dilution.
- Two color discs included (indoor and outdoor light) so this portable iron test kit gives accurate readings under fluorescent lighting in a lab or in direct sunlight at a job site.
- 100 tests per kit with replaceable FerroVer iron reagent (p/n 92799-CA). When the included reagent runs out, order a refill pack and keep testing. No need to replace the comparator box, discs, or viewing tubes.
- Complete field-ready kit in a rugged carrying case. Everything needed for the test ships in one case: FerroVer iron reagent powder pillows, two color discs, a comparator box, two 18 mm viewing tubes, and step-by-step instructions.
How to Use This Iron Water Test Kit
- Fill two viewing tubes with 5 mL of sample water.
- Place one tube (the blank) in the left side of the comparator box.
- Add one FerroVer iron reagent powder pillow to the second tube.
- Swirl the tube until an orange color develops.
- Place the treated tube in the right side of the comparator box.
- Hold the comparator box up to a light source and rotate the color disc until the colors match.
- Read the iron concentration directly from the scale window in mg/L.
Use clear, non-turbid samples for accurate results. Samples with iron above 30 mg/L require dilution before testing.
Applications
This iron water test kit is used wherever dissolved iron levels affect water quality or equipment performance. Common applications include:
- Well water testing for residential and commercial systems with iron staining or taste complaints
- Municipal water treatment plants monitoring source water and distribution systems
- Industrial process water analysis for boiler feed, cooling towers, and recirculating systems
- Wastewater treatment facilities tracking iron levels in influent and effluent
- Environmental field assessments at construction sites and remediation projects
An iron test kit for well water is the primary application. Wells in iron-bearing geology produce iron above the 0.3 mg/L guideline, and this water quality test kit provides the measurement to size a treatment system. For iron concentrations near the 0.3 mg/L guideline where finer resolution is needed, the Hach IR-18A (0.02 to 1.00 mg/L) covers low-range testing..

Frequently Asked Questions
How to test iron levels in water?
Fill two viewing tubes with your water sample. Add one FerroVer iron reagent powder pillow to one tube and swirl. Place both tubes in the comparator box, hold it up to light, and rotate the color disc until the colors match. The reading in the scale window shows your iron concentration in mg/L.
What is an acceptable level of iron in drinking water?
Health Canada and the EPA set a guideline of 0.3 mg/L for iron in drinking water. Above that level, water develops a metallic taste and causes red, yellow, or brown staining on fixtures, laundry, and appliances. This water quality test kit measures from 0.25 to 7 mg/L.
What is the phenanthroline method for iron testing?
The 1,10-phenanthroline method reacts a chemical reagent with dissolved iron in a water sample to produce an orange color. The stronger the color, the higher the iron concentration. This Hach iron test kit uses FerroVer iron reagent powder pillows, which contain the phenanthroline chemistry in a pre-measured format for consistent results.
Hach IR-18B vs IR-18 iron test kit?
The IR-18B (146401-CA) replaces the discontinued IR-18 (146400). The IR-18B measures 0.25 to 7 mg/L iron with a 0.25 mg/L increment, while the old IR-18 covered 0 to 4 mg/L with a 0.1 mg/L increment.
How does a color disc test kit work?
A color disc test kit compares a treated water sample against a standardized color reference. The FerroVer iron reagent reacts with dissolved iron to produce an orange tone. By rotating the disc in the comparator box until the sample color matches, you read the concentration directly from the viewing window. No electronics or batteries needed.
How do you test for iron in water at home?
Use a portable iron test kit for well water like the Hach IR-18B. Collect a sample, add the reagent, and match the color against the disc. This kit works without power or lab equipment, so homeowners can test at the kitchen sink and get a reading in minutes.
