New - Open Box - Bought for hobby vineyard but never used.

The Ultimate Winemaker’s Companion! Includes everything you need to analyze SO2, pH, and TA in one kit
Tests take less than 2 minutes to perform and are incredibly accurate with pH readings to 1/100 of a point
Combines the SO2 detection of the SC-100A and the pH/TA analysis of the SC-200 into one compact instrument
Audible buzzer and indicator light alert you to when the test is complete
Affordable wine analysis averaging roughly $1 per test
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

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

Attach the pH electrode, set aside storage solution, rinse with DI water and blot gently with a paper towel.
Press the power button then press the ‘Mode’ button and switch the SC-200 into ‘Cal’ mode.
Calibrate using the pH 4 and pH 7 reference standards provided. Put the SC-200 in pH mode.
Take 5 mL sample of wine, place in a beaker. Take a pH reading.
Accurate TA Test

For TA test, withdraw 5 mL of the TA Titrant with the syringe.
Take 5 mL wine sample and add ~15 mL of deionized water.
Put SC-200 into TA mode, place clean pH electrode gently in solution.
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.
Multiply the titrantion volume by 2, the TA conversion factor, results in g/L Tartaric Acid.
