User manual HANNA INSTRUMENTS HI 3811

[. . . ] Alkalinity is critical in the treatments of drinking water, wastewater, boiler & cooling systems and soils. The Hanna Alkalinity Test Kit makes monitoring easy, quick and safe. The compact size gives the user the versatility to use the kit anywhere. [. . . ] · Take the titration syringe and push the plunger completely into the syringe. Insert the tip into HI 3811-0, and pull the plunger out until the lower edge of the plunger seal is on the 0 mL mark of the syringe. · Place the syringe tip into the cap port of the plastic vessel and slowly add the titration solution dropwise, swirling to mix after each drop. Continue adding titration solution until the solution in the plastic vessel turns yellow. · Read off the milliliters of titration solution from the syringe scale and multiply by 300 to obtain mg/L (ppm) CaCO3. x 300 = CaCO 3 Low Range Determinations If results are lower than 100 mg/L, the precision of the test can be improved as follows. · Remove the cap from the large plastic vessel. Rinse the vessel with water sample, fill to the 15 mL mark and replace the cap. Proceed with the test as described before. To obtain the result for both Phenophtalein and Total Alkalinity multiply the values on the syringe scale by 100. Note: Push and twist pipet tip onto tapered end of syringe ensuring an air-tight fit.
