An Easy-to-Use, Fast and Affordable All-in-one Solution


The HI84534 is a low-cost, easy to use automatic minititrator and pH meter designed for the rapid and accurate analysis of Total Titratable Acidity in Vinegar. The HI84534 minititrator is a valuable tool because of its ability to eliminate subjective factors including color indicators, errors in mathematical calculations or erratic titrant additions, it will quickly become a valuable acidity analysis tool of vinegar.


The HI84534 incorporates a precise piston dosing system, which allows for a highly accurate determination of the amount of titrant used. It is also capable of dynamic dosing, making testing both faster and more accurate. Pump calibrations are performed with the provided Hanna standard and help assure the accuracy of the measurement.
An intuitive interface makes the instrument simple to use and the dedicated HELP key guides the user through set-up, calibration status, and troubleshooting. 

This mini titrator includes a pre-programmed analysis method based on the Standard Methods of Water and Wastewater Determination. It uses a powerful algorithm which analyzes the shape of the electrode
response in order to determine when the titration reaction has reached completion.


This mini titrator is also designed to be used as a benchtop pH/mV meter. The CAL Check function not only ensures an accurate pH reading when the HI84534 is used as a pH meter but also an accurate titration since the
endpoint is determined by a set pH value.

 

Vinegar


Vinegar is made when acetic acid bacteria is added to an alcohol beverage such as wine. The bacteria will eat the ethanol and produce a tart, pungent liquid know as acetic acid. The acetic acid concentration in vinegar typically
ranges from 4 to 9 % (w/v). The pH of vinegar is typically between 2.5 to 3.0, depending on the acetic acid concentration. Vinegar can be made out of anything that has alcohol (ethanol) in it, including wine, beer,
and hard cider. The type of vinegar depends on what liquid the ethanol has been fermented in. White vinegar is made a vodka type liquor made from grain, while apple cider vinegar is made from apples and balsamic vinegar is
made from grape must. Outside of the United States popular vinegars include rice, coconut and cane. Vinegars are commonly used in food preparation, medicine, agriculture and in cleaning solutions.

The titratable acidity of vinegar is determined by titrating the sample with a strong base to a fixed pH. The end point is determined by the potentiometric input and the results are typically expressed as % (g/100mL) or g/L
acetic acid. The HI84534 minititrator method is based on the Official Methods of Analysis of AOAC International.
