The CBME80B and CBME120 are standalone, lightweight LIDAR ceilometers engineered for reliable, continuous cloud base height and vertical visibility measurement in civil and military aviation, meteorological, offshore, marine, and helipad environments. The two models share a common design and feature set, differing only in measurement range – allowing operators to select the variant that matches their operational ceiling requirements.

Measurement Range Options

• CBME80B: 7,600 m (25,000 ft)
• CBME120: 12,000 m (39,370 ft)

Key Features

• Accuracy: 5 m or ±0.25% of measured distance, whichever is greater
• Detects up to five cloud layers
• Low power diode laser with eye-safe output
• Powerful microprocessor with real-time digitizing for accurate detection of fine stratus cloud patches below solid cloud bases
• Proven MTBF of over 10 years
• Compact, lightweight, low power consumption – suitable for fixed and mobile installations
• Built-in test system for fault indication; easily replaceable electronic subunits
• Simple installation and minimal service needs
• IP66 rated; operating temperature -40°C to +55°C
• Power supply available in 110V or 230V AC
• Standard 2-year warranty, extendable up to 5 years

Connectivity & Integration

• RS-232 and RS-485 interfaces for local control and data acquisition, plus other interfaces on request
• Compatible with various display and recording units
• Supplied as a preconfigured unit (main assembly, sensors, power equipment) with full support for integration into existing systems, or as part of a turn-key Mesotech AWOS or HMS system

Accessories & Options

• 1 m stand for fixed installations
• Robust Leister blower for enhanced detection in precipitation
• Sunshield for high-sun/tropical environments
• Cloud Presentation Suite – graphical display software for Windows PC
• Mobile version with integrated display
• Contamination detection
• Green color option (RAL 6003)
• Integrated display

Applications

• Aviation: civil and military cloud height and vertical visibility reporting, meeting or exceeding FAA, ICAO, and WMO requirements
• Meteorology: precise atmospheric data for forecasting and public safety
• Offshore & Marine: robust performance on ships, oil platforms, and other maritime installations
• Helipad Operations: cloud base measurement to CAP437 standards for offshore helicopter landing areas
• Air Quality Monitoring: atmospheric layering and stability data to contextualize ground-level pollution measurements
