Apple Nano Touch Technology
Advanced and practical: Different from infrared technology, it solves the problem of incorrect touch caused by chalk dust falling on the infrared frame or blocked by the sleeve.Precise touch: higher precision and better sensitivity. Compared with the infrared touch technology invented 25 years ago, it has better stability and more advanced.Convenient operation: Meet with teachers' daily habits, support multiple people writing on it at the same time, five-finger erasing, ten-finger switching screen.
Green-eye protection
Edutech Smart Blackboard also has the advantage of eye protection. Our company used spectrum shift technology to completely remove blue light of 415 to 455 nanometers that is harmful to human eyes. This ensures green and healthy eye protection and has Chinese optic protection accreditation. There is no safety or maintenance issue because the screen is blast proof and scratch proof. The screen is also anti-glare. The display effect is very lifelike because our product uses 4K High Definition display screen.
Six-in-one application software, easy to operate
Edutech Smart Blackboard contains a six in one software with functions of documents camera, electronic whiteboard, wireless projection, PowerPoint annotation and replay. By clicking one button, the user can employ the according function. For example, when teacher is about to demonstrate a test paper or courseware, the teacher only needs to gently put the paper on the documents camera platform and click "Projector". It is also easy to operate when the teacher wants to annotate while explaining the courseware. Just directly annotate on it! For example, the sixth question's answer is C. You can directly write on the screen to annotate. If you want to explain one specific question, it is also quite simple. Just click Snapshot and crop out the fourth question and insert it into the whiteboard. Then, you can continue to explain and make further annotations. The whole process is very easy and convenient.
High-cost performance
Edutech smart blackboard has high-cost performance, including not only the traditional touching function, but also the functions of computers, high-speed cameras, etc. You can write on the whole page when the power is turned off.
4K high-definition display
Scratch-proof
Our smart blackboard is scratch-proof and solves the storage problem of the equipment.
1~2 Channels L-band Satellite Optical Transceiver
Introduction
CLB satellite L band signal optical transceiver consist of transmitter and receivermainly convert the L-band analog signal or digital signal from LNB of satellite antenna into optical signal, and transmit it via fiber in fully transparent, high quality and long distance methodMainly apply in space satellite, military satellite live satellite L-Band fiber uplink /downlink
Features:
1. Use in multiple antenna signal transmission such as C band, KU band etc., transmit 1~2 channels 950MHz~2150MHz satellite signal
2. Adopts 19 1U standard frame chassis, the color LCD on front panel shows the information of optical power, temperature, working voltage, input or output RF Level etc.
3. For LNB, transmitter can supply power via RF port, on does not supply power for it, if supply power, the output voltage is +13V or +18V Max. output electric current is 450mA user can set it via LCD color screen
4. The LCD of optical transmitter can show optical transmitting power, LD working electric current, the temperature of optical transmitter, the output Voltage for LNB, Input RF signal level
5. Optical receiver can supply power via RF port, input voltage is +13V or +18VMax. Output electric current is 300mAalso can supply power via the AC220V dual power supply of the equipment

TC-2088
diffused silicon pressure transmitter is a high-precision
pressure sensor that utilizes resistive diffused silicon elements
as sensitive components. It boasts advantages such as small size,
light weight, good stability, strong interchangeability, and high
reliability. The sensor employs imported diffused silicon or
ceramic cores as pressure sensing elements, crafted through
special processing techniques to achieve high accuracy and
excellent stability.
The output signal of the diffused silicon pressure transmitter is
a unified 0-10mA or 4-20mA signal, compatible with various types
of moving coil indicators, digital pressure gauges, electronic
potentiometers, and other devices for precise pressure
measurement and control.
This pressure transmitter finds wide application in industries
such as petroleum, chemical, and metallurgical industries for
pressure measurement and control of steam, air, and other
corrosive media. It is also suitable for monitoring high-voltage
switchgear operating currents in power plants, smoke emission
monitoring in environmental protection departments, water flow
indication in high-rise building water supply networks in
building drainage projects, pharmaceutical liquid filtration,
fermentation tanks in food processing industries, boiler water
replenishment systems, air conditioning ducts, oil field water
injection, and continuous measurement of media in pipelines,
among other applications.
Seamless connection, high contrast ratio, high refresh rate, 16 bit high grey level. Ergonomic design, aspect & resolution ratio 16:9.
Each cabinet aspect ratio 16n9 easy to reach 2K 4K 8K HD requirements.
Hight precision CNC fabrication, the cabinet precision is within 0.05mm seamless assembly.
HD pixel pitch led display has a 3840Hz refresh rate which eliminates scan lines and flicker in your display on camera.
