1.Introduction to Portable Visibility detector
Portable visibility detector is able to measure visibility indoors or in any restricted environment, providing real-time visibility values.The BN20 Portable visibility detector uses forward scattering method to measure the total extinction coefficient of the air and calculates the current visibility.It is widely used in emergency, road traffic, meteorological and other scenarios.
2.Technical features of Portable visibility detector
1.Integrated portable design, light weight, easy to carry, ready to use;
2.10.1-inch high-bright touch screen, displaying data and historical curves in real time; ☆
3.Built-in large-capacity SD card (8G), data is saved in real time, and it supports query and export;
4.Built-in large-capacity lithium battery, which is convenient for outdoor emergency use;
5.The instrument shell is high-quality aluminum material, and the whole machine has excellent waterproof, dustproof and collision-proof performance;
6.Built-in watchdog circuit to ensure reliable and stable outdoor operation for a long time;
7.The instrument communication and power interfaces both contain lightning protection designs, which greatly reduce lightning strikes and static damage;
8.24V power supply, low power consumption, and long-term power supply;
9.The digital interface uses RS232 and is uploaded actively without adaptation protocol;
3.Portable visibility detector execution standards

Road Weather Sensors employs the forward-scattering method to measure the air extinction coefficient and calculate visibility. It is capable of identifying five distinct phenomena—fog, rain, snow, mixed precipitation, and clear conditions—with an identification accuracy rate of ≥95%. With a...
In the cold winter, transmission lines often face severe challenges of icing. When conditions such as low temperature, high humidity, and specific wind speed occur simultaneously, the phenomenon of icing on transmission lines is likely to form. Line icing not only increases the mechanical load on co...
Handheld weather stations provide convenience for people to obtain meteorological data anytime and anywhere. Among them, mechanical handheld weather stations and ultrasonic handheld weather stations are two common types. What are the differences between them? How should consumers choose?Differences...
