Product Introduction:

The HT/BUJ-1G/2 portable laser ceilometer is an intelligent device independently developed and manufactured by Qingdao Hotech Automation Technology Co., Ltd. It is designed for handheld monitoring of cloud base height, cloud layer thickness, and solid target distance, with real-time display of measurement results. It supports both manual single measurement and automatic continuous operation.

II. Working Principle

Based on the laser ranging principle, the device's laser transmitter emits periodic laser pulses into the atmosphere. The laser receiver captures the backscatter signals from cloud layers and the atmosphere. The processor collects and processes the received signals, and through inversion calculation, obtains the extinction coefficient of the atmosphere at various heights, thereby identifying cloud layers and calculating the cloud base height value.

III. Functional Characteristics

The device can measure cloud base height or solid target distance either vertically or obliquely. Featuring small size and light weight, it is not restricted by station layout space and offers flexible measurement and operation. Equipped with a built-in lithium battery, the observed data can be displayed on the LCD screen in real-time and simultaneously stored inside the device for convenient future retrieval and data analysis. With an ergonomic design, it supports both temporary handheld observation and long-term continuous observation when mounted on a tripod.
