Shanghai Xinrui ZDJ-4001, 4001P automatic potentiometric titrator

1、 Usage Overview:

ZDJ The series automatic potentiometric titrator is a laboratory analytical instrument with high analytical accuracy, specifically designed for detecting acid levels in food. Instrument according to《GB5009.229-2016 National Food Safety Standards The design of "Determination of Acid Value in Food" adopts automatic potentiometric titration method to determine the acid value in food. Can be applied to various inspection agenciesFood enterprises, research institutes, and laboratories have the advantages of easy operation, high accuracy, and strong intelligence.

2、 Product features:

1. The instrument adopts a new microprocessor technology, which can simultaneously display information such as year, month, day, time, working status prompt, measurement results, etc. It has the function of switching between Chinese and English display.

2. The instrument can support automatic determination of acid levels in food and automatic calculation of acid level titration results (including solution calibration, blank titration, sample titration, etc.) in dedicated titration modeFunction). You can also use the specialized titration analysis software from Xinrui Company to connect to a computer, find the titration endpoint through a first-order differential curve, and automatically calculate the titration result.

3The instrument has multiple titration modes, including manual titration, repeated titration, preset endpoint titration, and pre titration. Different electrodes can be used for different drops in the instrumentDetermination, including acid-base titration, redox titration, precipitation titration, complexometric titration, non-aqueous titration, and other titration methods pH Measurement, potential measurement, temperature measurement and other functions.

4. The instrument adopts an integrated automatic directional valve device, controlled by a microcomputer, which does not require manual control or switching of injection or replenishment methods, making it very convenient for usersuse. It has the advantage of high degree of automation.

5. The instrument adopts an integrated metering pump design, which can accurately calculate and control the injection volume, facilitate user replacement, and reduce the mutual interference problem of different solutions used in different titrations.It has the advantages of high accuracy in titration capacity, good repeatability, and simple maintenance.

6. The titration system pipeline is made of acid, alkali, and corrosion-resistant materials, and can perform non-aqueous titration. The mixing system adopts PWM Modulation technology, software speed regulation, stable and reliable.

7. The instrument is equipped with a temperature sensor interface, which can achieve automatic temperature measurement and PH The temperature compensation for measurement can be done manually or automatically.

8. The instrument has a power-off protection function, and the data stored inside the instrument and the set parameters will not be lost in the event of shutdown or abnormal power failure.

9. The instrument can be used through RS232 Interface or USB Interface (optional), capable of real-time transmission of current measurement data to the computer for subsequent data processing.

10 ZDJ-4001P The titrator is equipped with a built-in micro printer that can print the current measurement data in real time. The instrument is equipped with a large capacity SD Memory card, supports GLP Standard, canTo store 2000 Set the titration results above. It can facilitate users in storing and querying data. Can be moved and used on the computer.
