Souvan poze kesyon ak repons pou enfrawouj tèmomèt

1, Relasyon ant gwosè mezi sib ak tanperati a mezi distans (konsèp nan optik rezolisyon )?

efikas D D mezirab objektif varye diferan distans, so li sib distans lè mezire ti sib. distans distans koefisyan K nan sib /sib targets sib. distans distans koefisyan K nan sib sib sib. distans distans koefisyan K nan distans koefisyan K yon enfrawouj tèmomèt defini kòm rapò distans sib la sible, i.e. K=L/D

Li relasyon ant gwosè a mezi sib ak tanperati a mezi distans

2% 2c How chwazi emissivite teste sibstans?

Enfrawouj thermomètr yo jeneralman ki baze sou blackbody (emissivite ε{0}}00) gradye, men in reyalite, emissivity sibstans mwens 1.{{3%. 7d}. Se poutèt sa, lè mezire vre emissivite dwe emissivite emissivite sibstans jwenn emissivity objè radyasyon radyasyon 22.

3, How to measure targets in a strong light background?

4% 2c How mezire ti sibstans?

Konsantre: objektif lantiy deplase tounen ak pou mezire sib sib sib pi gwo pase ti nwa nwa dot, konsantre omèt. Refer manual espesifik metòd nan konsantre

When mezire ti sibstans, in lòd asire mezirement mezirement presizyon

Thermometer yo ta dwe fiks sou yon tripod (si ou vle akseswa)

(2) Focusing is required, that is, use the small black spots in the eyepiece to aim at the target (the target should be full of small black spots), adjust the lens back and forth, and shake the eyes slightly. If there is no relative movement between the small black dots measured, focusing is completed
