Heat Stress Meter Anemometer, Wet Bulb Globe Thermometer Wind Speed Meter

Key features

• 4-in-1 Anemometer WBGT Heat Stress MeterThis handheld meter combines wind speed (0-30 m/s, ±5% acc.), WBGT (0-50℃), temperature (0-50℃, ±0.6℃ acc.), and humidity (0.1%-99.9%RH) in one device. Press MODE to switch between wind speed and WBGT display — one tool, four readings, complete heat safety monitoring.
• WBGT Alarm Heat Hazard IndicatorThe screen displays 4 heat stroke risk levels based on WBGT: Caution (26.7-29.4℃), Extreme Caution (29.4-31℃), Danger (31-32.2℃), and Extreme Danger (>32.2℃). Set alarm temp (20-50℃ adjustable) via SET. When exceeded, backlight turns RED and buzzer sounds — never miss a warning.
• High Accuracy SensorEquipped with 7 sensitive fan blades for high accuracy wind speed readings (±5% acc.) and a black globe sensor that captures heat radiation for precise WBGT calculation (0-50℃, 0.1℃ resolution). Pre-calibrated before shipment — reliable data you can trust, right out of the box.
• Handheld Anemometer 5 Wind Speed UnitsUnlike other meters that hide unit symbols, this device clearly shows all 5 units on screen: m/s, ft/min, knots, km/h, and mph. Quick-response buttons with zero lag — press WIND to switch units, press MAX/MIN to view max/min/real-time readings. No guessing, no confusion.
• Indoor Outdoor Dual Modes & Wide ApplicationPress OUT/IN to switch between indoor and outdoor WBGT modes — outdoor mode factors in sunlight for accurate readings.
