Product Introduction

The KH.CQX-5 Five Parameter Micro Meteorological Instrument uses continuous frequency converting ultrasonic signals to measure wind speed and direction by detecting the relative phase. Compared with traditional ultrasonic anemometers, it avoids the need for high precision timers and eliminates errors caused by sensor startup delays, demodulation delays, and temperature fluctuations.
With a highly integrated design, the KH.CQX-5 measures five meteorological parameters including ambient temperature, relative humidity, wind speed, wind direction, and atmospheric pressure. It enables 24-hour continuous outdoor monitoring and outputs all parameters simultaneously through a digital communication interface.

Features

• The ultrasonic probe is hidden in the top cover to prevent interference from rain, snow, and natural wind shielding.

• Integrates five elements: wind speed, wind direction, temperature, humidity, and atmospheric pressure.

• Advanced sensing technology ensures real-time measurement without starting wind speed limitations.

• Strong anti-interference ability with watchdog circuit and automatic reset function for stable operation.

• High integration with no moving parts, zero wear, and maintenance-free, eliminating the need for on-site calibration.

• Durable ASA engineering plastics and 304 stainless steel construction ensure long-term outdoor performance without discoloration.

• Standard RS485 communication interface with MODBUS protocol, optional RS232, USB, or Ethernet interfaces for flexible real-time data output.

• Optional wireless transmission module with minimum transmission interval of 1 minute.

• Snap-on probe design ensures secure installation and prevents inaccuracy during transport.

Application Scenarios

The KH.CQX-5 can be widely used in meteorological monitoring, urban environmental monitoring, wind power generation, marine vessels, aviation airports, highways, bridges, and tunnels.
