Radiation Shield GARNI RS1 — ambient temperature sensor housing for outdoor measurements

GARNI RS1 is a radiation shield designed to house ambient temperature sensors and commonly temperature-and-humidity probes for outdoor measurements. The enclosure reduces direct solar radiation and radiative heat exchange with the environment, helping to stabilise sensor readings and minimise measurement bias caused by sun exposure and thermal radiation. It is suitable for use in meteorological stations, environmental monitoring sites and as protection for HVAC outdoor sensors.

Advantages

The shield’s design provides passive protection from solar radiation and improves air circulation around the sensor, which reduces local heating and influence from reflected heat sources. Its construction enables quick installation of standard-size probes and offers consistent performance under variable outdoor conditions. The lightweight and weather-resistant materials contribute to durable operation with minimal maintenance.

Suitable for

• Outdoor ambient temperature measurement in meteorological stations
• Environmental monitoring networks and air quality stations
• HVAC systems requiring protected outdoor temperature or humidity sensors
• Research plots and agricultural monitoring where solar shielding is required

Key specifications

• Purpose: radiation shield for ambient temperature and temperature/humidity sensors
• Function: reduces solar radiation and radiative heat exchange effects on sensors
• Material characteristics: lightweight, weather-resistant construction suitable for outdoor use
• Design features: vented/laminated structure to improve airflow around the sensor
• Mounting: compatible with common mounting arrangements for outdoor sensor housings

How to use

Install the sensor inside the radiation shield according to the sensor manufacturer’s instructions so that the sensing element is centred within the ventilated area. Mount the assembled shield at a representative measurement location away from nearby heat sources, reflective surfaces and obstructions that could disturb airflow. Ensure the shield is securely fixed and oriented as recommended for the site; periodic inspections are advised to remove debris and check for secure attachment.

Usage recommendations

For accurate ambient temperature and humidity readings, place the shield at the standard measurement height for the application and away from artificial heat or reflective surfaces. If passive ventilation is insufficient in low-wind conditions, consider positioning the shield in a location with natural airflow or pairing with an aspirated mounting solution. Regular cleaning of vents and occasional inspection will maintain reliable performance.
