The consistent performance of the Meteoshield Pro really does go to show that it's worth getting.

E si ,in questo momento il meteoshield pro è probabilmente il miglior schermo passivo in circolazione, le sue prestazioni in qualsiasi condizione meteo o luogo dove si mette sono sempre al top  :-)

The thing that does impress me is the fact you put it literally anywhere and it gets accurate temps & beats the Stevenson screen in temperature accuracy. Amazing piece of work honestly.

I think the magic is in the spiral design. Hot air rises, therefore there is always a natural convection that occurs with the spiral design. The spiral design is what allows air to move. Every other radiation shield you see is just a sandwich of layered sections that trap the air. Other weather station manufacturers should take note.

Esatto , il suo punto di forza è la sua forma elicoidale, questa forma in sostanza lo rende come un ventilato, il vento si incanala e viene spinto dentro , ma l'altra cosa importante e l'interno formato da una specie di schermo di colore nero, che assorbe  la radiazione riflessa , insomma davvero ben fatto e studiato in modo eccellente  :-)

Someone should paint the inside of their Davis 7714 or Ambient SRS100LX with black paint and test. Of course they would need a control, with another one that was not painted.

eheheheh io ho già fatto questa prova però non ho usato il davis , ma un mio auto costruito che batteva il davis , ma npn c'è stato nulla da fare , quando c'era vento tutto ok , andava quasi al pari con il pro, ma in assenza di vento e alta radiazione solare , il distacco aumentava in modo importante 0,6/0.7 decimi  di differenza , il nero sotto serve per la radiazione riflessa , ma per il vento il nero non ha nessuna efficacia,  ](*,) , comunque un confronto nel prossimo futuro sarà ;inserire un sensore sonda ecowitt dentro il davis7714 e fare la parte di sotto dei piatti neri , per vedere che succede  [tup]

Not surprisingly Ecowitt are working on a new radiation screen design and I hope that they will be looking closely at the Meteoshield design.
Probably be a while as they are very busy with new projects but at least its on the board!

Mandrake,
Did you send them the tip to make it spiral?

Ecowitt is just fascinating in how much they listen to their customers for product innovation and improvement.

That's very interesting and would massively improve the quality of their external temp readings. I guess the radiation shield will also cost a bunch less than the high quality ones from the competitors.

yes I also felt that there is something planned that will concern the shielding of the sensors, we hope because it is something that is missing from the ecowitt and extremely important [tup]

Ecowitt suppling good radiation shields for their temperature sensors would help them surpass Davis & become one of the top dogs in the industry personally. They are one of the only companies in this field that listen to customer feedback & they are on the way to the top.

 giornata molto calda con una massima di 33.7 , ma sempre con l'immancabile vento da nord , a quanto pare sarà una costante per una decina di giorni altri  comunque il lastem in queste condizioni mi piace come va con uno scostamento medio di 0.38 decimi non è male , ma sono soddisfatto anche della ws80 che fa la sua bella figura soffre un pò la mattina , ma poi si riprende bene  ;)

I'd personally think that the WS80 would perform worse out of them all since it's mainly a wind sensor & I'd have temperature accuracy lowest of my priorities. Impressive none the less. Thank you for the tests!

Sì è vero chi ha la WS80 la usa per l'ottimo anemometro
ad  ultrasuoni, però se invece di avere quel piccolo schermino per schermare il sensore , avesse uno schermo più performante , be sarebbe un'ottima stazione , non arriverebbe al meteoshield pro ma il davis 7714  lo batterebbe senza problemi , che poi guardando i grafici che ho pubblicato , già adesso va alla pari al Davis ,  ;) ha anche un gran vantaggio la WS 80 un'elevata reattività ,

Agreed on the WS80.
When I first received the pre-production model of the WS80 I really recognised that Ecowitt/Fine Offset are deadly serious at this game because it was such a step up from the standard sensor suite in terms of build and design.
In my mind there is no doubt that they aspire to surpass Davis in terms of quality and capability if you want it, whilst offering a relatively good base level to get started.
