One lean, mean wine analyzing machine. The SC-300 combines the SO2 detection of the SC-100A and the pH/TA analysis of the SC-200 into one power-packed instrument.

It’s built on the same hardware and software as our other two analyzers, so the accuracy is superb. And it’s just as easy to use – The audible buzzer and visual stop light will automatically let you know when you’re tests are done!

Because it does not rely on a color change, the SC-300 eliminates the guesswork in Ripper sulfite tests, especially in red wines!

Why Choose Vinmetrica’s SC-300?

Where else will you find a single, compact instrument that can measure sulfite (SO2), pH and TA (Titratable Acidity) levels throughout the fermentation and aging process? Even in Red Wines!

It’s Accurate:

  • SO2: ± 2 ppm Free SO2.
  • TA: ± 0.2 g/L Tartaric acid
  • pH: better than ± 0.02 pH units

Quick! – Less than 2 minutes per test!
Affordable – About a $1 per test!*
Easy to Use – No mystery solutions, pumps or tubing.

*SO2 (Sulfite) Tests cost approximately 70¢ / Test (the cost of the reagents per test). If you do a combined pH and TA analysis, the cost of reagents for the pH/TA test is approximately $1.12 / Test.

Complete Wine Testing Kit – Includes Everything Needed to Analyze Sulfite (SO2), pH and TA (Titratable Acidity) levels in Your Wines & Musts:

  • SO2 reagents
  • pH/TA reagents
  • Two titration beakers
  • Two 5 mL syringes
  • Two transfer pipettes
  • SO2 electrode
  • pH electrode
  • 25 mL sampling pipette (for SO2)
  • 5 mL sampling pipette (for pH/TA)
  • The SC-300 Operating Manual

The SC-300 analyzer gives accurate SO2, pH and TA values. Kit includes everything to perform about 50 sulfite tests and 30 TA tests: both electrodes, all reagents, pipettes, syringe and beaker.

A Quick Overview – Wine Analysis Procedures with the SC-300:

Easy SO2 Test

  1. Attach SO2 electrode, press the power button, change to SO2 mode and press enter.
  2. Draw up 5 mL of titrant into the syringe and place 25 mL of wine in beaker.
  3. Add ~2 mL of the acidifier and ~2 mL of the reactant to wine.
  4. Place and hold the SO2 electrode in the wine sample and swirl beaker.
  5. Add titrant from syringe dropwise until 15 second long endpoint signal reached.
  6. Multiply the titration volume by 20, the SO2 conversion factor, results in ppm Free SO2.

Simple pH Test

  1. Attach the pH electrode, set aside storage solution, rinse with DI water and blot gently with a paper towel.
  2. Press the power button then press the ‘Mode’ button and switch the SC-200 into ‘Cal’ mode.
  3. Calibrate using the pH 4 and pH 7 reference standards provided. Put the SC-200 in pH mode.
  4. 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 from the syringe dropwise until the endpoint is reached indicated with the visual and audible signals. Record the volume (in mL) of titrant used.
  5. Multiply the titrantion volume by 2, the TA conversion factor, results in g/L Tartaric Acid.

It can accomplish three important tasks in one unit at a more affordable price than three seperate items.

After research, it seemed that this kit would meet my needs for a small winery.
Lolita Olson on Dec 27, 2018
reviews of the SC-300 suggested it needed a few more parts. It sounds like this includes everything one would need in a basic test kit.

How does one keep the PH probe from failing in long term storage?
kevin gill on May 5, 2021
BEST ANSWER: While I do not have the answer, I believe that so long as the probe is kept in the small vile of solution you should be good. You can also send the people at Vinmetrica a question. they have been great at answering my concerns.....cheers.

Pricey, but accurate
Unless there is something uniquely complicated about the gauge or the probes, this seems like a lot of money to spend. However, that being said, the unit is accurate, well made, and relatively easy to use once you have everything in place.

worth the investment
While it might take a couple tests to get it all dialed in and learn just what to expect, this setup allows for easy accurate testing at a low cost per test. Support is excellent if you are new like me. Make sure you have some distilled and de-ionized water on hand to do the tests, as they are not included in the kit.
