Cloud Height Measurement

1、Cloud Height Measurement Product Overview

Cloud Height Measurement obtains cloud height for meteorological and aviation applications by shooting a laser pulse directly upward and measuring the time it takes for the pulse to return.Cloud Height Measurement is an advanced meteorological and environmental monitoring device that utilizes lidar technology to measure cloud height, thickness, and multi-layer cloud information. It features a lightweight design, low power consumption, and simple, convenient operation. Applicable scenarios for this product include airports, ships, and training facilities. Its operating environments span inland regions, maritime areas, and high-altitude plateaus.

2、Cloud Height Measurement Key Features

a) Cloud Base Height Measurement: Emits vertical laser pulses toward the sky; by precisely calculating the time difference between the laser signal reaching the cloud base and returning to the instrument, it accurately measures the cloud base height.

b) Multi-Layer Cloud Differentiation: Features multi-layer cloud detection capabilities, allowing it to penetrate cloud layers to identify and calculate the structure of up to three distinct cloud layers, while simultaneously reporting the cloud base height for each individual layer.

c) Observation Mode Switching: Offers flexible observation modes. Users can select a single-measurement mode to quickly obtain current data, or choose a continuous automatic observation mode to monitor the dynamic changes in cloud height over extended periods.

d) Data Recording and Transmission: Capable of storing both raw data and measurement results; supports the querying and exporting of historical data, and facilitates external communication via an RS485 interface.

e) Auxiliary Aiming: Facilitates aiming through the use of a built-in aiming reticle on the device body, supplemented by a live video feed displayed on the LCD screen.

f) Display Function: Equipped with an LCD screen that provides real-time displays of current cloud height, battery level, device status, and other relevant information.

g) Dual Power Supply (Battery and External): Features a dual-source power supply design. It includes a built-in, high-capacity rechargeable lithium battery to support extended mobile field operations, and is simultaneously equipped with an external power input port. When connected to an external power source, the device automatically switches to external power supply mode and charges the internal battery, ensuring uninterrupted operation and meeting the requirements for long-term monitoring at fixed locations.

h) Tripod Mount: The bottom of the device body features a standard universal 1/4-inch threaded interface, allowing for convenient mounting on professional tripods. This feature effectively minimizes measurement errors caused by hand tremors during handheld operation, thereby enhancing stability and data accuracy during prolonged, continuous observation sessions.
