Water hardness is an important factor to consider when it comes to water quality. The HANNA HI 3812 Hardness Test Kit is a reliable and accurate way to test for water hardness in both residential and commercial settings. This kit is easy to use and provides quick results, allowing you to make informed decisions about water treatment options. In this article, we will walk you through the process of testing water hardness using the HANNA HI 3812 Hardness Test Kit, as well as provide tips for interpreting your results and potential treatment options
Here used HI 3812 Hardness Test Kit
HIGH RANGE - 0 to 300 mg/L CaCO3
• Remove the cap from the small plastic
vessel. Rinse the plastic vessel with
the water sample, fill to the 5 mL
mark and replace the cap.
• Add 5 drops of Hardness Buffer through the cap port
and mix carefully swirling the vessel in tight circles.
• Add 1 drop of Calmagite Indicator through the cap port
and mix as described above. The solution becomes a redviolet
color.
• Take the titration syringe and
push the plunger completely into
the syringe. Insert tip into HI
3812-0 EDTA Solution and pull
the plunger out until the lower
edge of the 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 the titration solution
until the solution becomes purple, then
mix for 15 seconds after each additional
drop until the solution turns blue.
• Read off the milliliters of titration solution from the syringe
scale and multiply by 300 to obtain mg/L (ppm) CaCO3.
LOW RANGE - 0 to 30 mg/L CaCO3
If result is lower than 30 mg/L, the precision of the test can
be improved by following the procedure below.
• Remove the cap from the large
plastic vessel. Rinse it with the
water sample, fill to the 50 mL
mark and replace the cap.
• Proceed with the titration as for the high range test.
• Read off the milliliters of titration solution from the syringe
scale and multiply by 30 to obtain mg/L (ppm) CaCO3.
Range 0 to 30 mg/L (ppm) CaCO3
0 to 300 mg/L (ppm) CaCO3
Smallest Increment 0.3 mg/L [in the 0-30 mg/L range]
3 mg/L [in the 0-300 mg/L range]
Analysis Method EDTA titration
Sample Size 5 mL and 50 mL (average)
Number of Tests 100 (average)
Case Dimensions 200x120x60 mm (7.9x4.7x2.4")
Shipping Weight 460 g (1 lb.)

Did not understand

[@shahinooralam3435]

Colour change হবার আর অতিরিক্ত সলিউশন এড করার দরকার ছিল কি?
কারন ওই সলিউশনের পরিমান টাই মূলত টোটাল হার্ডনেস নির্দেশ করবে।
যা ৩০ বা ৩০০ দিয়ে মাল্টিপ্লাই করতে হবে।

[@HuntingThecreativity]

জি একদম ঠিক বলেছেন। কনফিউশানের জন্য এটা আরো এড করা হয়েছে যেন বিষয় টি আরো পরিস্কার হয়।
