Vinmetrica’s SC-200 Measures pH and TA (Titratable Acidity) levels in wines easily, accurately and quickly. Knowing your pH and your TA parameters is essential during the winemaking process to insure you are making the highest quality wines.

Complete Kit Includes Everything You Need for Your First 30 pH/TA Tests.

  • The Vinmetrica SC-200 pH/TA Meter
  • pH/TA reagents
  • replacement pH electrode storage solution
  • a Titration beaker
  • a 5 mL syringe
  • a pH electrode
  • a 5 mL sampling pipette
  • The SC-200 Operating Manual

Simple pH Procedure

  1. Attach the pH electrode and press the ‘Power’ button
  2. Press the ‘Mode’ button and switch into ‘Cal’ mode.
  3. Set aside the storage solution, rinse with DI water and blot gently with a paper towel.
  4. Calibrate with the pH 4 & 7 reference solutions. Press enter when the ‘Cal’ LED flashes. Put into ‘pH’ mode.
  5. Take 5 mL sample of wine, place in a beaker. Take a pH reading.

Accurate TA Test

  1. For TA test, withdraw 5 mL of the TA Titrant with the syringe.
  2. Take 5 mL wine sample and add ~15 mL of deionized water.
  3. Put SC-200 into TA mode, place clean pH electrode gently in solution.
  4. Add TA Titrant dropwise until the endpoint is reached with the visual and audible signals. Record the volume (in mL) of titrant used.
  5. Multiply the titration volume by 2, the TA conversion factor, results in g/L Tartaric Acid.
Interested in testing something other than wine? The SC-200 can be used to test beer, cider or any other beverages, you just need to know what Acid you’re testing for.
For example, you can do pH and TA on beer with the SC-200. The pH is independent of the beverage or whatever solution it’s measuring.  The TA is also; it’s just a matter of how you calculate the final answer.   Wine TA is usually reported as tartaric acid but the titration actually measures acidity as equivalents per liter (eq/L). If you assume the acid is mostly tartaric (true for wine) then you use the conversion factor for tartaric acid (75), as we do in our kit. For measuring the acidity levels in a sour beer you would use the factor for lactic acid (90). So you could just convert as:          g/L lactic = 90/75 * g/L tartaric. To determine the conversion factor for the acid you are looking for, simply look up the molecular weight of the acid. The molecular weight of Lactic Acid is 90, so that is why we used it in the equation above.

How It Works

The SC-200 kit provides a pH electrode and reagents for calibration and determination of pH and titratable acidity (TA) values in wines and other samples. The pH value is simply determined by placing the calibrated electrode into a sample and reading the value. TA is determined by titrating a 5 mL sample of wine to an endpoint pH of 8.2* with the TA titrant (0.13N NaOH) from the syringe in the kit. From the known concentration of the TA titrant and its volume required to reach the endpoint, the TA is simply calculated (results are in units of g/L tartaric acid).

Top 5 Reasons Why Vinmetrica’s SC-200 is the Right Choice

  1. Easy to use: it’s audible buzzer and visual stop light indicators let you know when you’re done titrating
  2. Accurate: for TA:0.2 g/L Tartaric acid & for pH: better than 0.02 pH units
  3. Quick results: less than 2 minutes per TA test & even quicker for a pH test
  4. Quick pH calibration: takes about 2 minutes, & only needs to be done once per day
  5. Inexpensive about a dollar per test!



  • pH range: 1.0 to 13.
  • Accuracy: better than 0.02 pH unit.
  • Autocalibrate on pH 3.00, 4.01, 7.00, 10.00
  • TA mode: Accuracy: +/- 0.2 g/L Tartaric acid.
  • Sensitivity: Detects down to 0.2 g/L Tartaric Acid
