Me gustó el producto, por la precisión que entrega vs precio está bien. Lo utilizo, para verificar las condiciones internas de invernaderos.

Funciona muy bien. Ideal para medición en zonas de trabajo. He contrastado los datos con otros medidores y la variación es mínima. Yo lo uso con trípode, ya que para una medición adecuada lo tienes que dejar unos minutos.

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

For being cheap it is very accurate on average it’s off maybe 1mph vs my kestrel and I gave 10xs the cost for my kestrel
