Introduction

Analysis of the core content of the standard

This standard specifies the technical specifications of the seed cotton color detector, with the following highlights:

Optical parameters: Adopting D65 light source (6500±200K color temperature)
Measurement accuracy: Rd value error ±2.0, +b value error ±1.0
Environmental adaptability: Working temperature -20℃~40℃, humidity 20%~85%RH

Comparison of key technical indicators

Parameter	Test range	Allowable error	Detection method
Seed cotton reflectance (Rd)	40.0-85.0	±2.0	45° incident light method
Yellow depth (+b)	2.0-15.0	±1.0	Spectral analysis method

Instrument structure and working principle

A typical MJAZY-D65A detector includes:

Optical detection module: 45° incident angle optical system
Data processing unit: embedded microprocessor
Software system: Complies with ISO/CIE color space standards

Application case: After a cotton company in Xinjiang adopted this instrument, the accuracy of seed cotton grading increased by 23%.

Suggestions for the implementation of the standard

Key points for purchasing and selection

Check the D65 light source certification documents
Require a standard color plate calibration report
Verify the stability of Bluetooth/USB communication

Daily maintenance specifications

Perform white board calibration before each use
Check the light source attenuation every month
Avoid using in a condensing environment

Quality control measures

Period	Inspection items	Qualification standards
Daily	Appearance inspection	No mechanical damage
Weekly	Standard board test	Error ≤ nominal value
