Use stable and reliable red, green and blue primary colors to judge, and display three curves in real time to titrate standard acid consumption and CEC content. Help users to monitor distillation, calculation, and titration process in real time, so that users can know what to do instead of traditional electrode potential method and single-wavelength colorimetric method.
It has a prompt whether the ammonia gas is completely distilled to avoid the outflow of erroneous data.
Piston pump with intelligent automatic variable and variable speed technology, as small as 0.8ul/step.
Instrument shell: ABS engineering plastics are used to avoid being corroded by sulfuric acid and to ensure the insulation of the instrument.
With condensate water cut-off sample protection function.
Distillation and titration are carried out at the same time to neutralize the evaporated ammonia gas, avoid the escape of ammonia gas as much as possible, and reduce the detection time at the same time.
The titration cell is in an open state and is not affected by external light.
Automatic detection of cooling water flow, water pressure, alkali, boric acid, diluent, distilled water shortage prompt.
It has real-time detection and control of the temperature of the still.
It has the function of real-time detection and prompting of whether the protective door is closed.
Automatic cleaning of the titration vessel and tubing.
Manual and automatic dual modes can be switched at will, and the entire test process can be tracked and displayed in real time.
The distiller is controlled by double liquid level, and a mathematical model is used to find that the still is in a dry burning state. Eliminate the risk of dry burning in the still.
Adjustable distillation power: ensure good recovery of low concentration samples.
Distillation method Double distillation mode.
Automatic acid addition, automatic base addition, diluent addition, distillation, titration, storage, and print out the calculation results.
Data and detection conditions are traceable.
Optional: automatic input of balance data, wireless transmission of test data to the computer.
