pH testers are an economical option to perform an acidity measurement. With a pH meter, the end point can be determined by performing a manual titration.
We offer a wide range of portable pH meters that can be used for manual titrations for acidity. Each still requires a graduated burette filled with a base to determine the amount of base to reach the pH end point.
A variety of benchtop meters are available including those with a large, color LCD that can log and display graphs in real time. The graphing function is useful in seeing the equivalence point of a alkalinity titration.
Hanna Instruments offers a variety of titration systems.
Potentiometric titration systems include single and dual channel options and a version with a single or dual dosing pump. These sytems are the most accurate in dosing with a 40,000 step dosing pump that can deliver microliters of titrant. Some titration systems can perform two titrations consecutively such as salt and acidity performed in food analysis.
The mini-titrator is a Hanna Instruments innovation that brings the accuracy and precision of our potentiometric titration systems to the users performing manual titration with a pH meter. The mini-titrators use a syringe pump to accurately dose the titrant. The titrant is pre-standardized so no specialized glassware or analytical balances are need to make the titrant.
Electrodes & Probes
Many electrodes are available for measuring pH. The pH electrodes include those supplied with our mini-trators for wine and dairy products, others include versions made specifically for non-aqueous titrators.
The probes made for non-aqueous titrations use chemically resistant materials to withstand harsh chemicals, and offer a double junction design to replace the electrolyte with lithium chloride dissolved in the solvent used with the sample.
Solutions required for performing acidity titrations include calibration buffers and maintenance solutions used for cleaning and storage.
Everything you need to keep your Hanna Instrument products working their best.
Chemical Test Kits
A variety of chemical test kits are available including those for basic acidity of water and one made specifically for determining olive oil acidity.
Portable photometers, like chemical test kits, are reagent based design in which there is a color change to indicate the endpoint. The portable photometers use the Beer-Lambert principle to determine the color change. Detection of the color change is more accurate than subjective visual interpretation.
Reagents include the reagents used with chemical test kits and photometers. In this category the titrants and solutions for titration are also included. All titrants are pre-standardized and sealed to maintain the value of the solution.
