New product of U85 micro laser distance sensors use highly focused class 2 laser to detect objects or measure distances, and can return a measured value via varieties intface( serial, usb, rs232, rs485, bluetooth etc.). The electronic distance sensor is a very small Laser Distance Sensor, but high resolution up to 1mm and long distance measuring sensor - teachable measuring range of up to 30m. Extremely accurate distance sensing sensors, errors down to ± 1mm. And the mini sensors and measurements support continuous measurement function, great for compact solutions(eg: robots) with the smallest Laser Distance Sensor of the world!

Talking about the use of ductless fume hood
In order to effectively protect the operator during the experimental operation in the ductless fume hood, there are many precautions in use:
1. Keep the transparent plate of the fume hood clean, do not put stickers and other items to prevent obstruction of the line of sight.
2. When there is no experimental operation, the fume hood cannot be placed with chemical reagents. Always store the reagents in the medicine cabinet.
3. Be sure to follow the chemicals marked in the clean gas ventilating cabinet. Do not use chemicals not listed.
4. As long as it is an experiment of toxic chemicals, it must be placed in a fume hood. Remember to wear simple protective equipment such as goggles and protective gloves. The test bench and instrument should be cleaned up in time after the operation.
5. Regularly check whether the filter is saturated. Contact the manufacturer for filter replacement in time. Otherwise, once the filter is saturated and not replaced in time, it will lose its protective effect.
6. Do not pile up debris in the fume hood to avoid uneven airflow and not reach the proper surface wind speed, resulting in decreased adsorption efficiency.
