🧪 Measurement Principle
Measurement uses reflectance from LED-illuminated reaction pads.
Reflectance (R) is calculated by:
R=Tm⋅CsTs⋅CmR = \frac{Tm \cdot Cs}{Ts \cdot Cm}
For single-wavelength (BLD) tests: R = Tm / Cm.
Temperature-corrected reflectance:
Rt=R+A(T−27)R2(1−R)2R_t = R + A(T – 27)R^2(1 – R)^2
Measured items: GLU, KET, BIL, NIT, PRO, URO, pH, BLD, LEU, S.G., Color-tone, ALB, CRE, A/C, P/C.

🎨 Color-Tone Analysis
23 tone and hue combinations (Light / Normal / Dark × Hue types).
Reflectances at 430 nm, 565 nm, 635 nm, 760 nm yield hue and tone results.
Classifies urine color into Colorless, Yellow, Orange, Brown, Red, Violet, Blue, Green, Other.
