🌬️ 5-in-1 Environmental Meter
Measures wind speed, air flow, temperature, and humidity. One compact tool for HVAC, outdoor sports, sailing, and ventilation testing.
📐 5 Selectable Wind Speed Units
Easily switch between m/s, km/h, ft/min, knots, and mph. No mental conversions needed – read what you’re used to.
🌡️ Temperature & Humidity Monitoring
Built-in sensors give you real-time readings from -10°C to 45°C (14°F to 113°F) and 20% to 90% RH. Perfect for checking environmental conditions on site.
🔄 MIN/MAX Recording Mode
Long press the Mode button to track minimum and maximum values automatically. Ideal for spotting gusts, sudden temperature drops, or humidity spikes.
📏 1/4" Metal Tripod Mount
Compatible with any standard tripod (tripod not included). Allows hands-free monitoring for air balance testing or long-term outdoor tracking.
⚡ Simple One-Hand Operation
Short press to power on, short press again to toggle °C/°F. Short press Mode to cycle units. Long press Mode for MIN/MAX. No steep learning curve.
❄️ Wide Operating Range
Works reliably from -10°C to 45°C (14°F to 113°F) and up to 90% RH. Built for real-world job sites, not just lab conditions.

✅ Solves Real Problems Users Face
For HVAC engineers: Check airflow from vents, measure supply/extract temps, and monitor humidity – all in one go. No more juggling multiple tools.
For sailors & kite surfers: Know the exact wind speed in knots before heading out. The compact size fits in a pocket or kit bag.
For gardeners & allotment owners: Track wind chill and humidity to protect sensitive plants. The tripod mount (tripod not included) lets you leave it running overnight.
✅ Affordable Without Cutting Corners
The ±5% wind accuracy (±2°C temp, ±3% RH) meets professional needs for most field work – yet the price stays well below bulky, single-purpose meters.
✅ No More Unit Confusion
Whether your reference uses m/s (meteorology), mph (UK driving analogy), or knots (marine) – one click cycles through all five. Your brain will thank you.
✅ Built for the British Climate
Operating range covers cold UK winters (-10°C) and humid summers (90% RH). Store it down to -20°C without damage. It’s tougher than it looks.
