Hello everyone, yesterday's screens / stations trend 03/06/2022
[ You are not allowed to view attachments ]
things get interesting, maximum temperature 35.2 ° with moderate ventilation from the north, Davis vp2 pro ventilated disappointing excellent performance "as always" of the RAD 02-14 (metspec) also the Davis 7714 goes very well, the meteoshield pro let's say it is assuming it's ok in these weather conditions look at the ecowit GW1001 in comparison with the Davis vp2 pro [ You are not allowed to view attachments ] good vision at all

Good evening to all screens / stations trend of 06/15/2022 [ You are not allowed to view attachments ]
sunny day with light / moderate wind from NW, look at the last graph of the pdf, it shows the temperature difference between a meteoshield pro with wh32ep mounted on the roof, and a meteoshield pro always with wh32ep mounted on the ground,

good vision

Good afternoon everyone, screens / stations trend of yesterday 17-06-2022 [ You are not allowed to view attachments ]
very hard day for Ecowitt stations, look at the graphs from 06:00 to 09:00 period where the ventilation is absent and the sun begins to rise, in these conditions the ventilated Davis is the master together with the RAD-14, good vision at all

very interesting data and graphs yesterday, demonstrate the importance of the wind in measuring the temperature
look at this graph, sudden changes in temperature as the wind direction changes,

windy day which for the screens is a big advantage, consequently the differences are contained, different speech for the ventilated vp2 pro which is the worst in these situations,

Hello everyone, screen trend of 24-07-2022
[ You are not allowed to view attachments ]
An emblematic day to establish the quality of a screen or station, but also to understand the importance of the wind in measuring the temperature, from sunrise to 10:30 in the morning wind almost completely absent, look at the trend of the ecowitt, then the trend of sunscreens, there is a world

with this I don't mean that AIOs are not good or anything like that, on the contrary ... but only that we are on two different levels, even VP2 pro ventilated in these situations gives the best of itself, I wish you a good vision

Hello everyone, yesterday I painted the interior of the davis 7714 finally opaque black, we have been talking about this thing for years, now the time has come to see if this modification brings benefits, or is pejorative [ You are not allowed to view attachments ] [ You are not allowed to view attachments ] [ You are not allowed to view attachments ] [ You are not allowed to view attachments ]

Hello everyone, here is the data from the first day of testing the Davis 7714 with black inside
[ You are not allowed to view attachments ]
a really good performance, even if we don't have to give too much importance, there was enough wind some clouds, but we can say that in these weather conditions the davis keeps pace with the Big, we continue to test

Still confirmations yesterday 08/26/2022 [ You are not allowed to view attachments ] the comparison is made with a meteoshield pro

Very interesting yesterday day, good solar radiation and weak wind, the black davis performed very well, to say the least,

for the moment I am very satisfied, it is exceeding my expectations

How did you calibrate your sensors before the modification of the shield?

let's continue with the weather comparisons, data from yesterday 29/08/2022

day with a lot of instability, but these days are also needed to understand how the screens / stations respond to temperature changes caused by a storm

Good morning everyone, let's resume this topic, with yesterday's data of yesterday 13/01/2023, obviously to be taken with a grain of salt given the period, low solar radiation and low temperatures, they are not the best to make valid comparisons, but they are useful also these conditions to evaluate the behavior of the screens in all weather situations,
