Acidity is an important parameter used to determine the quality of water (surface water, drinking water, wastewater). Acidity affects chemical reaction rates, biological processes, and corrosion rates. Acidity can also be used to monitor contamination in wastewater and drinking water.
Total titratable acidity is a quantitative measurement of the ability of a water sample to react with a strongly basic solution to a specific pH value. Depending on the analytical method, acid titration can use a variety of chemicals. These can include strong acids (hydrochloric acid, nitric acid, sulfuric acid,…), weak acids (acetic acid, carbonic acid,…) and hydrolyzed salts (iron, manganese, aluminum,…).
Double junction pH electrode
The HI 84534 is supplied with the HI1131B, double junction, refillable combination pH electrode. The HI1131B has a spherical tip for use in water or liquid samples. The electrode provides a wide contact surface with the sample and is ideal for direct measurements or acid-based titrations.
Piston metering pump
The highlight of the HI84534 is its piston-controlled dosing pump. This dosing system uses a motor to help each dosing be very accurately dosed and the volume distributed into the sample is accurately determined. The piston-controlled burette enables the dosed titrant volume to be automatically adjusted based on the voltage response of the previous dispense. This type of dosing will help speed up the titration and save time, by allowing more titrant to be dispensed at the beginning of the titration and smaller doses to be dispensed as the titration approaches the endpoint.
Automatic stirrer
Integrated magnetic stirrer helps maintain automatic speed of 700 rpm, regardless of solution viscosity titration.
Main features on screen
– Instruction and help mode: HI84534 with friendly design, sharp keyboard, large screen makes use easy. In addition, the device is installed with tutorial software that, when activated, will guide the user on how to use the device step by step. During use, if there are any questions, users can press the HELP key to receive information support.
– Warning display: the user will be alerted in case an error occurs when using the machine (eg: the volume of titrant exceeds the allowable limit..)
On-screen titration curve: the mini titrator displays data throughout the titration, including real-time graphs.
– Record and review data: Save results as required: HI84534 allows saving up to 400 samples: 200 titration results and 200 pH/mV measurement results. These data can be stored on USB or transferred to a PC via the USB connection port.
– As a pH/mV measuring device: in addition to being a titrator, the HI84534 can also be used as a desktop pH meter, with automatic temperature compensation, automatic buffer solution recognition, and maximum calibration. 3-point multi-point, ±0.01pH accuracy, GLP data storage.
– CAL CHECK featureTM: The machine will automatically analyze the response signal of the electrode during the calibration process and notify the user of problems that may affect the measurement results such as contaminated buffer solution, dirty electrode. or cracking... the CAL Check feature not only ensures the accuracy of pH measurement but also helps ensure accuracy in determining the end point of the titration process.
