Force and mechanical measuring equipment
– HI84500 is a device to determine sulfur dioxide (SO2) free and total in alcohol quickly, conveniently and easily.
– Based on the Ripper method, combined with powerful algorithm settings and a specialized ORP electrode, the mini titration device can accurately determine the reaction end point.
– Integrated piston pump in dynamic pumping mode, automatically adjusts the amount of injected reagent based on the change in potential of the sample during titration, helping to save reaction time while still ensuring results reliable.
– Supplied with all necessary materials to measure sulfur dioxide on both low and high ranges.
– The supplied chemicals have been mixed in the correct ratio and packaged in a closed process including standard solutions, reagents and pump calibration solutions, no need for additional glass pipettes and analytical balances. .
Winemakers often add sulfur dioxide (SO2) into wine to prevent the growth of bacteria and unnecessary yeasts, and also acts as an antioxidant to prevent wine browning. SO2 Only partly incorporated in wine, the remaining part exists in free form, helping to preserve wine. SO content2 freedom plus SO2 The combination is called SO2 total. relationship between SO2 total and SO2 freedom is complex and varied between wines, depending on SO content2 addition and activity of compounds in wine (sugar, aldehyde, keto acid, quinone, anthocyanin...) with SO2.
SO content2 freedom depends on the content SO2 added, SO content2 available in wine and SO content2 will combine in the wine. SO2 Freely exists in wine in two forms: bisulfite (HSO3-) is the dominant form but does not have much effect, SO2 The molecule has a lower ratio but has the function of preserving wine. SO content2 Existence in molecular form depends on quantity SO2 free alcohol and pH index. Normally only 0.8ppm SO is needed2 molecular form is enough to preserve wine. To achieve that content, the wine's pH is 3.2 and 22ppm SO2 free. If pH increases to 3.5, the amount of SO2 essential freedom 44ppm.

SO molecule2 can be felt by human senses when it reaches 2ppm, this is the necessary content to best preserve wine. However, higher levels will be needed to preserve late-harvest, highly sweet wines. HI84500 can be used to test SO content2 freedom and SO2 total in all types of wine, including red wine, which is often difficult to test by classical titration due to the difficulty in detecting the color change of the indicator.
The HI84500 is a highly accurate, fast-paced instrument for analyzing SO content2 free and total. The mini titrator automatically dispenses reagents, detects the reaction end point and performs calculations in a much shorter time period than manual titration. In the article “Triage for Basic Wine/Grape Lab”, Richard Carey wrote “Hanna's titrator reduces reaction time to 75% compared to other instruments”.
The most important device of the HI84500 is the piston pump. Using a motor to control the operation of the piston makes it easier to control the pumping process, and the pumped reagent content is also more accurate. The pump mode installed on the machine is dynamic, so the amount of injected reagent will change depending on the change in voltage in the sample after each injection, so when performing a titration, the machine will inject many drugs. Test to shorten the time. When approaching the end of the reaction, the amount of reagent will gradually decrease to ensure the accuracy of the measurement process.
AUTOMATIC MAGNETIC STIRRING
The magnetic stirring device is integrated into the machine, automatically maintaining a speed of 700 rpm, making it easy for the device to titrate highly viscous samples.
HI3148B ORP electrode integrates CPS functionTM Helps the junction not be clogged during titration because the electrode will often clog easily when used in solutions with high dissolved solids content such as alcohol.
The HI3148B electrode uses a tubular junction made of glass and PTFE plastic covering the electrode body to help ensure that the flow of electrons moving in and out of the junction is always stable.
PTFE plastic coating and glass body ensure the electrode does not retain alcohol, minimizing electrode contamination leading to errors in subsequent measurements..
