good day to make comparisons between the various weather systems, excellent solar radiation ventilation on average 8 KM / H in the central hours, with fairly high temperatures, almost 35 °, excellent performance of Davis 7714 with the WH31 EP inside, very well also the 2 Metspec RAD02-14 always with WH31 EP inside, the ventilated davis vp2 pro suffers as well as the Lastem, hard day also for the WS80, very good instead the VN1900 (test), I just have to wish you good view of the graphs .  =D> [tup]

good day yesterday to see differences in the various systems, average wind about 5km / h good solar radiation and high temperatures
I added some photos to the graphs to better understand what we are comparing, sometimes we take this for granted, but for those approaching this world, it may seem Arabic  =D> [tup]

good day to make a comparison, excellent solar radiation and weak wind, you notice the suffering in the early hours of the sun of the 2 ecowitt, with important peaks, due to the small size of the solar screen, the ventilated vp2 pro is better when the wind is weak or absent, excellent performance of the Davis 7714 with wh31 EP sensor, and also the two Metspecs have excellent performance, to be noted in the wind charts, the ws68 which goes hand in hand with the Davis vp2 pro anemometer  =D> [tup]

hot day yesterday which recorded a maximum of 38.4 ° (2nd highest value of this year) these are the results ... amazing performance of davis 7714 with EP sensor inside good performance of 2 metspecs and ecowitt all in sum they defend themselves (better the vn1900) the lastem does what it can, for the vp2 pro ventilated, the same is always true, as long as the wind remains weak (below 5 km / h) it is unsurpassable, when the wind increases, the situation changes in the anemometric comparison to note the WS68 (ecowitt) perfectly aligned with the wind sensor of the davis vp2 pro  =D> [tup]

we resume after the mid-August holidays with our comparisons, yesterday windy day, but with good solar radiation, as usual when the wind is sustained, the ventilated screens suffer a little, while the performance of the davis 7714 is to be emphasized, which with the probe sensor positioned as Davis recommends, it works great :), excellent performance even of the 2 rad 02-14 of the Metspec, even the ecowitts defend well  =D> =D>

Haven't read the entire topic. Do you have a theory as to why the ventilated Davis performs so differently?

hello, when the wind is above 10 km / h the ventilated starts to worsen its performance, the reason is simple, the ventilated always sucks the same amount of air both with no wind and strong wind, while for passive screens with strong wind, they work better, as more air arrives on the sensor, when the wind is absent, or weak, the speech changes the ventilated ones work well and are unsurpassed, while the passives suffer, so before installing a solar shield, it is necessary to understand the microclimate of the installation area, if it is well ventilated all year round, there is no need to install a ventilated one, but better a good passive screen,

hi, look at how a ventilated davis vp2 behaves with the arrival of a storm, the response delay compared to a passive shielding is considerable  ](*,)

differences in rain guest
 [ You are not allowed to view attachments ]  
as is well known a bit of overestimation of the vp2 pro (single chamber) the wh40 a bit underestimates this too is well known, the meteorain of Barani is doing well, a bit under ... in short, a nice mess  :-|

Ivano,
can you rewrite the rain values ordered by position?
Maybe WN1900 and VP2 are close together?

hi Zoomx, there is no pre-established order, the reference is the manual TFA without lid, yes the VN-1900 marked the same amount of rain as the VP2pro ,this comparison was made in conditions of heavy rainfall, with a rain / rate up to 205 mm / h  ;)
