Hach alkalinity test manual

Very low maintenance The analyzer is self-cleaning, self-calibrating, and selfpriming. Advanced process control Two 4 - 20 mA outputs and two alarm relays allow quick configuration into standard PID control loop.

Constant protection Fast and accurate response minimizes process excursions. What's included? Calibration Interval: 60 minutes. Cycle Time: 8 minutes. Data Communications Distance: Maximum node-to-node distance is m '. Maximum total wire length is m '.

Dimensions: Depth: 21". Dimensions: Height: 21". Stablcal Turbidity Standards. Multi-Parameter Drinking Water Panels. Learn more about Claros The Water Intelligence System that turns your data into powerful operational insights.

The three primary alkali ions in water that contribute to alkalinity are: Bicarbonate HCO 3 - Carbonate CO 3 2- Hydroxide OH - Total Alkalinity Total alkalinity is a measure in parts per million of all the alkali all carbonate, bicarbonate and hydroxide ions present in a sample. Phenolphthalein Alkalinity Phenolphthalein alkalinity p-alkalinity is determined by titration to a pH of 8.

Quick Links Why Measure Alkalinity? Spectrophotometers Hach has been innovating with spectrophotometry for over 70 years and offers many of the leading spectrophotometers in the water analysis market.

Test Strips High-quality Hach chemistry on an easy-to-use test strip. Wastewater Treatment In wastewater treatment, alkalinity is an important parameter in determining the health and stability of various biological treatment processes.

What is the difference between hardness and alkalinity? Some common interferences in alkalinity titration methods include: Chlorine — Chlorine at levels above 3. To remove the interference, pretreat the sample by adding 1 drop of Sodium Thiosulfate Standard Solution, 0.

Color or turbidity — Color or turbidity can make it difficult to see the color change at the endpoint. Do not filter or dilute samples with color or turbidity. The CO 2 free water is not as critical in the titration vs. The colorimetric test is more sensitive to slight changes in CO 2 concentration due to the colorimetric detection method and small sample volume used.
