Product Overview

The REED R6200 WBGT Heat Stress Meter is a professional instrument for measuring environmental heat stress factors including ambient temperature, humidity, black-globe temperature, and calculating Wet-Bulb Globe Temperature (WBGT). This metric is used to assess how hot it “feels” in conditions where radiant heat, humidity and air movement all contribute to thermal load. The R6200 is ideal for workplace safety, sports environments, outdoor operations, and monitoring of personnel heat exposure.

Key Features

• Measures ambient air temperature, humidity, wet-bulb temperature, black-globe temperature, WBGT (indoor & outdoor), heat stress index, dew point and barometric pressure.
• WBGT “In/Out” function: shows heat stress value with or without direct sun exposure.
• Multi-line back-lit LCD display for simultaneous reading of multiple parameters.
• Built-in functions: Max / Min / Average / Data Hold.
• Internal memory stores up to 99 readings.
• User-adjustable audible alarm threshold for WBGT values.
• Tripod-mountable for long-term monitoring in the field.
• Selectable units (°C/°F) and low-battery indicator.
• Suitable for monitoring heat-stress in indoor or outdoor environments.
