BTMETERBT-881W Heat Stress Meter Anemometer, Digital Indoor/Outdoor WBGT (Wet Bulb Globe Temperature) Meter with Wind Speed, Ambient Temp, Humidity Tester

Nice compact meter, but it is not very accurate compared to an actual WBGT meter

It works. It takes several minutes for the black sphere to heat up in sunlight. Patience, Grasshoppah.Default alarm ranges aren't the same as milspec numbers. Tweak settings to suit your preferred standard.

For the price and the number functions it performs, this little handheld is quite useful. Wet bulb temp isn't all that hard to calculate if you know the temperature and humidity, but having it calculated on the fly is a nice feature. If you plan to do hiking, camping, or other long-term outdoor exposure activity, this could be a literal life saver.

Good for price, not as accurate as my Kestrel but will get you in the ball park.

We used this on a prescribed burn of a prairie recently. It's a helpful, handy tool! I appreciate the different modes, and the strong backlighting. It's a solid build. It did a great job of measuring wind speed. That's critical for a lot of things, such as ensuring you aren't lighting fires on windy days, or it you have a fire going, you can be ready for wind drafts if you measure them and know where they are. This is also useful for measuring wind and preventing drift during pesticide application.It's interesting to be able to measure the heat when you're performing a prescribed burn. It's a good way to show some of these "invincible" old timers that the heat levels are high and convince them to take breaks and drink water.Good quality anemometer!

I have to take the temperature outside for work purposes so this meeter works really well. easy to use and read and haven't had any issues with it.
