Salt & Acidity Titration
Get fast, accurate, and fully linked salt and acidity analysis for food labs with our Automatic Titrators.
Why Accurate Salt & Acidity Testing Matters
Salt and acidity are critical factors in ensuring the quality, consistency, and safety of food products. Our Automatic Titrators uses a linked analysis method to measure both salt and acidity in a single sample, delivering fast, accurate results in just minutes.
Salt Titration Principle
Titration is one of the most reliable and widely used methods for salt analysis in food manufacturing and laboratory quality control. During titration, silver nitrate (AgNO₃) is added to a sample containing chloride ions (Cl⁻). As the reaction occurs, insoluble silver chloride (AgCl) forms. The titration endpoint is detected using a silver billet electrode, which measures a rise in millivolts (mV) once all chloride ions have reacted and excess silver ions are present. This argentometric titration method provides a precise measurement of salt concentration, making it ideal for ensuring food quality, consistency, and safety in production environments.
Titratable Acidity (TA) Testing Principle
Titratable Acidity (TA) is a key measurement in food and beverage quality control, representing the total amount of acids present in a sample. TA is expressed as the concentration of the predominant acid (for example, acetic acid in ketchup or citric acid in fruit juice). During a titratable acidity titration, a sodium hydroxide (NaOH) solution is gradually added to the acidic sample until a fixed pH endpoint, typically between 8.1 and 8.3, is reached. This endpoint is precisely detected using a pH electrode, which monitors the neutralization reaction between the acid and base. This process provides an accurate measure of the total acidity, helping manufacturers maintain flavor balance, quality, and product consistency.

Better Together with an Autosampler
The HI922 Autosampler is an automated titration sample-handling system, and the perfect accessory for use with the HI932 Automatic Titrator. Autosamplers are useful if you have a high number of samples. Even if your throughput is low now, make sure that your titration system can integrate with an autosampler in the future.
Three tray size options available:
- 18 Beaker Tray (100mL beakers)
- 16 Beaker Tray (150mL beakers)
- 12 Beaker Tray (250mL beakers)
What to look for in an Autosampler:
- Customizable rinse cycle.
- The use of peristaltic pumps for reagent addition, sample leveling, or waste removal.
- Safeguards like optical infrared sensors to stop the process if there is a beaker missing.
- Automatic report generation so you can capture the data that you need for each titration sample and for the full tray.
- The ability to access and work with titration methods used by the titrator including the linked salt and acidity method.
