Met One 076B- Fan Aspirated Radiation Shield

A fan-aspirated radiation shield that improves temperature measurement accuracy by actively pulling air over sensors, reducing errors caused by solar radiation and heat buildup

  • Active fan aspiration minimizes solar radiation errors
  • High accuracy with temperature errors reduced to ≤ 0.05°F (0.03°C)
  • Supports up to four sensors, ideal for Delta-T measurements
  • Durable, corrosion-resistant design with AC or DC power options

Description

The Met One Instruments 076B Fan Aspirated Radiation Shield is a high-performance solution designed to deliver highly accurate temperature measurements in demanding outdoor environments. By using an electric fan to provide continuous aspiration, the shield effectively removes solar radiation errors and heat buildup around the sensors, reducing measurement errors to as low as 0.05°F (0.03°C). Its design supports up to four compatible sensors, making it ideal for advanced applications such as Delta T measurements, meteorological stations, and research-grade environmental monitoring systems.

Built for reliability and ease of use, the 076B features corrosion-resistant construction with a glossy white epoxy enamel finish and supports both AC and DC power options for flexible installation. The unit is simple to mount on a standard ¾-inch IPS horizontal pipe and allows straightforward sensor calibration and maintenance. With consistent airflow that is unaffected by ambient emissivity and a wide operating temperature range, the Met One 076B ensures stable, precise, and repeatable measurements even in harsh weather conditions.

Features

  • Errors decreased to 0.05°F (0.03°C) or less.
  • Simple sensor calibration and upkeep.
  • Allow for many sensors to be used for Delta T readings.
  • Radiation mistakes unaffected by ambient emissivity.
  • Interconnects with low conductivity.
  • Either DC or AC power supply.
  • Construction that resists corrosion with a glossy white epoxy enamel coating.
  • Simple installation and tower maintenance.
