Programmable Potentiometric Titration Apparatus, With Precision Metering Pump

The main unit of this apparatus incorporates the Microprocessor Based circuitry. A light feather touch key board is fitted on the side of an informative alpha numeric display. The display indicates the emf in millivolts generated during the titration process and also the millivolts generated with each addition of volume of titrant to the reaction beaker and the total volume of titrant added. The time interval between two consecutive additions of the titrant is also shown on the display.

All the factors such as the volume of titrant to be added in each addition, the time interval between two consecutive additions and the total volume of titrant to be added can be pre-set in the program with the key board.

The cabinet of the main unit itself serves as a sturdy titration stand with built-in magnetic stirrer. It holds the titration beaker with electrodes and inlet for titrant. A motorized precision dispensing unit housed in a small box can be kept on the main cabinet and connected on the side of the titration beaker making the equipment quite compact.
A highly precision metering dispenser correctly follows the commands from the microprocessor based circuitry in the main unit and accurately adds preset volumes of the titrant at pre-set intervals as per the set program.

Observing the parameters on the alpha numeric display such as the Volume of titrant added with each additions, time interval between consecutive additions, emf in millivolts being generated during the titration process and particularly that generated with each addition of fixed volume of titrant, one can easily draw the graph with clear indication of peak values. If necessary, a printer can be interfaced to print all these parameters to preserve a record.
