rozdiel medzi 2 LUX-meracmi, nechapem tym pojmom :)

[SKiLEX]

potrebujem si vybrat jeden z 2meracov osvetlenia
https://eshop.micronix.sk/meracia-techn ... a1119.html
alebo
https://eshop.micronix.sk/meracia-techn ... a1102.html

Data sheet od A1102 (286€)
Measurement principle .........................silicion photodiode with V(λ) filter
Spectral response error ........................less than 3.8 % according to CIE curve
Cosine error......................................less than 2.5 % up to an incident angle of +/- 85 degress

Overall accuracy match to DIN 5032 Class B standard


Data sheet od A1119 (212€)
Measurement principle...............silicion photodiode
Cosine error ...........................less than 3.0 % up to an incident angle of +/- 85 degress

Overall accuracy match to DIN 5032 Class C standard

Cervenym som zvyraznil to cim sa ten drahsi odlisuje od lacnejsieho
-co znamena ten V(λ) filter?
-co znamena ten druhy riadok "Spectral response error ........................less than 3.8 % according to CIE curve"



ak to ma vplyv na kvalitu merania?(ukazuje to cisto iba pocet luxov, nic viac...) je ten drahsi proste presnejsie merajuci, alebo co znamenaju tie data? ak by tu bol niekto kto aspon trosku tusi co to vsetko znamena...


a ano googlit som skusal
