A: During the use of the wing gate, the cardholder swipe the card outside the yellow line. Do not stand in the wing gate infrared alarm to swipe, when the wing gate opens to a certain extent, and there is an indication of the arrow, you can enter. It is best not to stay in it. It is easy to improve and improve the smoothness of the channel.
B: Cardholders should not fold or modify the card, or put the card and magnetic items together to avoid the card failure. If the card is lost, please contact the management department to re-register in time to avoid the information being leaked.
C: During the passage of the wing gate, it must not enter the channel of the wing gate. Do not force the wing slab to open up, so as to avoid the slamming of the slamming plate. The front personnel have already passed the middle point, and the personnel can swipe the card later. (Before using the old wing gate customers should pay attention, 2012 is the new, old wing The gate must be gated to close the gate before it can be swiped.) If the card is valid, there will be an arrow indicating that the gate is opened at the same time, so that it can pass quickly. The machine does not pass the alarm with an alarm or voice prompt. If the machine is faulty, immediately notify the management department to view it, and the professional engineer should perform maintenance.
D: Cardholders should swipe the card in the sensing area, so as not to be too high, so as not to touch the sensor area. The correct right hand card is parallel to the sensing area. 20-30mm away from the sensing area is the best. The voice of "Di" proves that the card has been successfully swiped.
E: The wing gates also need to be maintained frequently. Don't think that it is omnipotent. Regularly carry out dust inside and outside the chassis. (Refer to the maintenance and treatment method of the swing gate brake) to ensure the normal operation of the equipment.
Water quality chlorophyll content refers to the concentration of chlorophyll in water. Chlorophyll is a green biopigment that widely exists in plants, algae and some protists and is a key molecule in photosynthesis. The chlorophyll content in the water body can reflect the biomass in the water body and the health of the ecosystem. High chlorophyll content usually indicates eutrophication of the water body and may lead to eutrophication phenomena such as cyanobacterial blooms and hypoxia. The online chlorophyll analyzer adopts the advanced principle of fluorescence method, which can reduce the influence of stray light and has excellent repeatability and stability. RS485 digital interface, supports Modbus protocol, the Chlorophyll Sensor adopts an environmentally friendly design, with an automatic cleaning brush, and the cleaning time and interval can be set on the Chlorophyll Controller. Chlorophyll analyzers are of great significance to the protection of water environments and ecosystems. Daruifuno online chlorophyll meter is used for measuring the chlorophyll a in water, it is widely use for surface water monitoring.
