HOLDPEAK Wind Speed & Heat Stress WBGT Meter, Digital Handheld Anemometer, Wind Gauges with Temperature Humidity for Outdoor Workers, Iron and Steel Foundries

I bought this to teach my parents about the concept of WBGT, illustrate why shade is so important, and help us all develop a feel for what safely working in the yard feels like. I don't know if it's exactly accurate, but it's close enough to give a general idea of how safe or unsafe a situation is.

works great, arrived on time and works and looks as described.

Item does as advertised to give information as needed.

Buen material, el sensor es bastante sencible....ayuda bastante que se pueda cambiar las unidades de medición

If you just need something to capture the max wind speeds observed in your immediate area, this should be just fine. However, if you're seeking to capture several readings, logged by date and time, then this is not the right tool. Also, the temperature readings seem suspect to me. I was getting readings upwards of over 100 degrees on a day that was showing by other thermometers to be in the low 90's and 20% relative humidity. It meets my needs for quick wind speed readings but not much else.

The main reason i got this was jsut to measure wind speed. but it also has humidity and temperature as well as web bulb temperature and gives you and indication of heat stress.wind speed seems to work well, though I have no way to test its accuracy.in / out - it took me a while to figure out what this really is .... in, is the air temperature, and out is the black bulb temperature. so in direct sunlight, the "out" or black bulb temperature will be a lot higher than the air temperature. so keep this in mind, basically the heat you feel in the sun as opposed to the shade.it takes some time for those temperatures to settle out, so don't expect an immediate temperature reading unless it has been in the environment for like 15-20 min.so as far as heat stress, one is the heat stress when you are outdoors in the sun, and the other is indoors in the shade.I do like the features that warn you about a high heat index, as well as the RH feature.oh, a minor note, the backlight changes color as the heat index rises, but, you can't see those colors in the bight outdoors. .. still you do not that it is needed as it also has a bar that underscores the warning level. .. but just a small note about that.

Now I don't have a professional grade tester to compare the measurements. However, this appears to be rather accurate with humidity and temperature. The instructions are nice and straightforward, and you are provided a small Philips and batteries. The most important feature is the backlight, without it I couldn't read the screen at all.
