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.
1.Control system: Adopt a single-chip computer control system, which is characterized by:
(1) High degree of integration, high-quality chip, powerful function.
(2) With the PID temperature control function of automatic power adjustment, it can be used in instruments with different digestion temperatures, and can accurately and stably reach the set temperature in about 4 minutes.
(3) Nine major components such as controller, optical signal conversion, temperature signal acquisition, relay, etc. are integrated into the control system, which reduces the line connection and reduces the failure rate of wiring.
(4) Adopt CMOS technology and RISC architecture to achieve high-speed and low-power operation. It is more stable in environments that require long-term operation.
2.Multi-pass valve assembly: select the reagent sampling timing, flexible and diverse channels, with the advantages of small volume, easy maintenance, long service life and so on.
3.Metering components: peristaltic pump + infrared photoelectric system combination to achieve accurate measurement of trace reagents. Peristaltic pump negative pressure suction, there is an air buffer zone between the reagent and the pump tube, which avoids the corrosion of the pump tube, and at the same time makes the reagent mixing more concise and flexible.
4. Sealed dissolution component: high-temperature and high-pressure dissolution system accelerates the reaction process and overcomes the corrosion and air pollution of the equipment caused by the volatile corrosive gas of the open system.
