1.High range measurement of low concentration: ring sampling is used to reduce the number of dilutions, and the repeatability is better. For this kind of high-range measurement of low concentration, the advantage is particularly obvious.
(1)With the automatic compensation function of anti-turbidity interference, there will be no measurement misjudgment when collecting turbid water samples;
(2)It has the function of eliminating bubbles, and the effect on the sewage generated by bubbles is obvious, such as the sewage generated by bubbles in photovoltaic factories, printing and dyeing factories, etc.
2.Free queue: With 25 powerful queue bits, customers can choose tasks (calibration, zero-point verification, sample verification, span verification, water measurement sample, 72h queue) according to their own needs and fill in the corresponding queue bits, select the mode of execution queue (continuous or whole point), and then start the queue, and the device will follow your It is required to complete the measurement tasks in order;
3.Multiple quality control functions: zero point/span/sample verification, blank test, reserved parallel sample and standard recycling interface.
Power-on self-inspection, automatic reset, upper and lower limit warning, liquid shortage alarm, power-off protection, waste liquid separation, multiple measurement modes, key parameter display, (operation/verification/calibration) log.
4. On-screen instruction manual: split and refine the instruction manual into a single interface on the screen, only describe the functional operation of this interface, the content is concise, 30 to 150 words, 15 seconds to finish, no anxiety, easy to understand and easy to learn.
