The constant temperature shaker has the following features and benefits:
1. The constant temperature shaker is the first step of multi-eccentric amplitude adjustable technology. It runs more smoothly and reliably, meets the requirements of more experimental operation modes, and has a large waist plate size and a large number of maximum loading vessels.
2. The first domestic application of the latest USB data transmission technology to the shaker can store data using ordinary U disk, making the experimental conditions of traceability and monitoring any time become a reality, convenient, fast, large storage, and can be wirelessly connected with the computer. .
3. Constant temperature shaker realizes program control temperature, speed and time, can realize temperature, speed and setting and repeat, step and step operation and automatic operation, automatic start, automatic shutdown, always display and other operation modes.
4. The constant temperature shaker has constant temperature and humidity function, automatic water level recognition system, low water level sound and light alarm function and automatic water supply. It prevents the sample from evaporating and drying, and optional light and ultraviolet disinfection function.
5. The constant temperature shaker has the motion parameter memory and password lock function, which can prevent complicated operation and think of operation errors, and display set parameters and measured parameters at the same time.
6. With power-off recovery function, the instrument can be started automatically after power-on, and run according to the original designed program.
7. It can be timed, the timing can be up to 999 hours, the end point automatically stops rotating and sound and light alarm.
8. When the motor overheats and the speed is out of control, the instrument will cut off the respective power supply and sound and light alarm.
9. It has automatic opening device for opening and closing the door and safety protection functions such as leakage, overcurrent protection and overload protection.
10. It adopts the most advanced large torque motor, with strong power and stable speed, ensuring continuous operation and maintenance-free.
11. With microcomputer automatic control system, the motor can start smoothly, accelerate and decelerate according to the design rate. It can prevent the sample from splashing and ensure the safety of the sample.
12. The constant temperature and rapid cooling system of the constant temperature shaker realizes instantaneous cooling; the automatic defrosting function ensures that the instrument can continue to operate for a long time under low temperature conditions.
13. The use of electronically controlled 眺-type closed loop heating, refrigeration system. Silent fan design and forced convection ensure a good thermostatic effect.
14. The constant temperature shaker adopts the streamlined whole machine shape, tempered glass, large window, ABS box, mirror stainless steel inner tank and cavity components, and inclined humanized control panel.
We may have ever heard of the Bullet Fixed Focus Camera/ Fixed Focus Bullet Camera HD/ Bullet Fixed Focus Journal Camera/ Fixed Focus Bullet Camera IR/ Fixed Focus Bullet Surveillance Cameras/ Fixed Focus Analog Bullet Cameras, so what is the Bullet Fixed Focus Camera? We know that the Bullet refers to the camera shape, so what about the Fixed Focus? Actually, the Fixed Focus refers to a type of the camera lens. Today let me introduce the camera lens for you.
The camera lens is the key equipment of the video system. The lens' quality (index) directly affects the overall index of the camera. The lens is equivalent to the lens of the human eye. As you know, if there is no lens, the human eye cannot see anything. That is to say, if there is no lens, then the output image of the camera will just be white without any clear image output; which is consistent with the principle of our home cameras.
Actually, there are many classifications for the camera lens. Today please let me introduce one classification for you---the classification according to the structure.
1. The fixed focus lens with the fixed aperture
The lens has only one focus adjustment ring that can be manually adjusted. Rotating the ring left and right can make the image on the CCD target surface clearest. There is no aperture adjustment ring, so the aperture cannot be adjusted, and the luminous flux entering the lens cannot be changed by changing the lens factors, but can only be adjusted by changing the illuminance of the shooting site. The structure is simple and the price is cheap.
2. The fixed focus lens with the manual iris
Compared with fixed focus lens with the fixed aperture, the fixed focus lens with the manual iris has an extra aperture adjustment ring. The aperture range is generally from F1.2 or F1.4 to fully closed, which can easily adapt to the illuminance of the shooting site, and the aperture adjustment is done manually. The illuminance is uniform and the price is cheap.
3. The fixed focus lens with the automatic iris
Compared with the fixed focus lens with the manual iris, the fixed focus lens with the automatic iris has an extra gear-driven micro motor on the iris adjustment ring, and a 3 or 4-core shielded wire is drawn from the drive circuit, then connected to the camera's automatic iris interface seat. When the luminous flux entering the lens changes, the charge generated by the CCD target surface of the camera changes accordingly, thenthe video signal level changes, and a control signal will be generated and transmitted to the automatic iris lens, so that the motor in the lens can perform the corresponding rotation to complete the task of resizing.
4.The electric zoom lens with the automatic iris
Compared with the fixed focus lens with the automatic iris, the electric zoom lens with the automatic iris two extra micro motors. One motor is connected with the zoom ring of the lens, and can control the focal length of the lens when it rotates; the other motor is connected with the focus ring of the lens, and it can complete the focus of the lens When it rotates with control from the former motor. However, due to the addition of two motors and an increase in the number of lens groups, the size of the lens has also increased accordingly.
All in all, it would be helpful to know about the camera lens if you want to know more about the Bullet Fixed Focus Camera and the whole video monitoring field.
