Potentiometric Titrator ZD-2A/CZD-3A
Potentiometric Titrator ZD-2A/CZD-3A

The ZD-2A potentiometric titrator is equipped with a 7-inch high-definition touch screen, a solenoid valve to control dripping, and an all-in-one machine with magnetic stirring. Supports automatic calibration, temperature compensation, data storage, USB/Bluetooth printing and cloud connection. It can perform pH/potentiometric titration, has pre-control, delay and other functions. It has three modes: manual/automatic/fixed value, and can store 500 sets of data. It is suitable for laboratory potentiometric titration capacity analysis.

Description

Product Features:

·Equipped with a 7-inch color high-resolution (1024*600) capacitive touchscreen, featuring high sensitivity and comprehensive parameter display.

·Adopts a solenoid valve to control liquid dropping, and the main unit is integrated with a magnetic stirrer—this design eliminates complicated instrument installation, ensures intuitive operation, and offers convenience and simplicity.

·It comes with intelligent functions including automatic calibration, automatic temperature compensation, data storage, USB output, clock display, wireless printing, cloud connection, and self-diagnostic information. An optional Bluetooth module is available for the instrument, supporting wireless Bluetooth printing to facilitate user operations.

·It is suitable for volumetric analysis using the potentiometric titration method in experimental applications.

·It can perform controlled titration based on pH value or potential, and control the titration endpoint according to the set potential (pH).

·It supports pre-controlled potential (pH) adjustment, allows setting the titration endpoint delay function, and can control the titration interval duration.

·Three titration modes: manual, automatic, and controlled (constant pH/potential) titration.
