I recently purchased a Bresser professional rain gauge. The order was delivered on time. However, I must make some criticisms of the equipment.
1 - The radiation shield does not fulfill its function very well and the temperature difference measured in the shade and with sun exposure is quite high and exceeds 4ºC. Apparently it has insufficient ventilation and spacing between "plates", the white paint used should be different (and possibly the use of black paint inside).
2 - The inclination of the walls of the rain gauge cone could be improved.
3 - The lack of higher edges at the top of the rain gauge cone reduces the accuracy of the measurement whenever heavy rain occurs (the drops bounce off the walls of the rain gauge)
3 - The absence of a filter and anti-bird thorns in the rain gauge means cleaning has to be more regular.
4 - It is not understood why they use a thermometer instead of a thermo-hygrometer.
5 - A bubble level should be included in the rain gauge and information for this need in the instruction manual. Incorrect leveling causes the weighbridge to malfunction!
I bought the equipment on sale, but I don't think it's worth the €79 originally ordered. Still, I think it's an interesting instrument for measuring temperature in the shade or at night (where measurements are much more rigorous) or for measuring precipitation (as long as it's not too strong).
