• The measurement process of this instrument is automated and does not require human operation, greatly reducing errors caused by human factors;
• This instrument adopts a self-developed safe, durable, reliable, and accurate automatic sampling, injection, neutralization titration, and waste disposal system to ensure the continuous and normal operation of the instrument;
• This instrument has a self calibration system that can calibrate the concentration of the neutralizing solution, automatically calibrate and deduct the acidity value of anhydrous ethanol (blank value), and calibrate the measurement of the neutralizing solution, greatly reducing measurement errors caused by various factors and improving measurement accuracy;
• This instrument uses different titration endpoint determination methods for different samples to ensure the accuracy and reliability of experimental data;
• *The design of the anhydrous ethanol and neutralizing liquid delivery pipeline ensures that the reagents do not come into contact with air during use, avoiding the influence of solvent evaporation and acidic gases in the air on the experiment, and reducing the harm to the staff's body;
• Users can choose the method of determining the number of samples to be placed simultaneously and the endpoint of titration according to their own needs;
• The instrument automatically discharges waste and cleans related pipelines after the measurement is completed, thereby reducing people's workload;
• This instrument can store 500 measurement data and has a historical data query function. It can record and print each required data as needed, and can be queried at any time;
• The instrument has the characteristics of resistance to voltage fluctuations, environmental electromagnetic interference, and strong electromagnetic compatibility (EMC). The appearance adopts a streamlined design, with a delicate and beautiful structure, and comfortable and convenient operation.
