lo tili que ha sido el dispositivo
Me gustó el producto, por la precisión que entrega vs precio está bien. Lo utilizo, para verificar las condiciones internas de invernaderos.
User
good tool for the price.
Works like It should, well built and readings seem to be accurate.
User
Compacto, todo en uno
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.
User
Not very accurate
Nice compact meter, but it is not very accurate compared to an actual WBGT meter
User
Pretty nice for being cheap
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
