Product Model: T8000-As
Measurement Principle
After the sample is filtered, it is pumped into the reactor, and the reducing agent is injected first to reduce the arsenic pentavalent to arsenic trivalent. Then the gas generator is added to convert the measured arsenic into a gas and be expelled, and the expelled arsenic gas is absorbed by the solution in the colorimetric tank. After absorption, the arsenic gas reacts with the absorption solution. The analyzer calculates the absorbance of the solution according to the color of the solution, and then calculates the total arsenic concentration in the sample according to its stored correction factor.
Notable Features
Stable and Reliable
In order to meet the requirements of industrial and environmental online, the electrical part and the chemical pipeline part are completely isolated, and the simple and stable optical detection device ensures that the instrument can run steadily for a long time.
Easy to Install
The T8000-As water arsenic online analyzer has successfully passed a series of tests to facilitate installation and setting, and only needs to connect the reagent, sample, waste liquid pipeline and power cord during installation, and can be started after setting parameters.
Automatic Calibration
The instrument terminates the analysis and performs calibration according to the calibration time selected by the user, checks and stores new calibration parameters.
Measurement Interval
The user can set the analyzer to remain in standby mode between two measurements to avoid drug waste.
