Multi Angle Spectrophotometer

Introduction

A multi angle spectrophotometer measures color and reflectance at different viewing angles. It is widely used in coatings and automotive industries. The system ensures accurate color evaluation. It solves single-angle measurement limitations. By providing multi-angle detection, it supports surface color consistency.

FAQ

Q1: What is the multi-angle spectrophotometer mainly used for?

A: It is used to measure colour and appearance of surfaces at multiple angles, which is important for quality control of metallic, pearlescent and textured coatings, plastics and automotive finishes. Multi-angle measurement captures the angle-dependent appearance that single-angle instruments miss.

Q2: What standards does the spectrophotometer comply with?

A: The instrument follows applicable ISO and GB/T standards for colour measurement, including geometric conditions and observer requirements. Measurement procedures should follow the applicable standard methods. Compliance documentation can be provided on request.

Q3: What is the warranty period for the spectrophotometer and key components?

A: The complete unit carries a 12-month warranty covering the optical system, electronics and controller. Calibration standards, lamps and accessories are excluded as consumables. Damage from improper handling or unauthorised repair is not covered.

Q4: Is the spectrophotometer difficult to operate?

A: Operation requires training in colour measurement, sample preparation and software use. The manual explains measurement geometry, calibration and maintenance, and remote guidance is available. Proper sample surface preparation is important for accurate results.

Q5: What is the typical lead time for order delivery?

A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

Q6: Does the spectrophotometer require calibration or verification?

A: The instrument should be verified periodically using calibrated reference standards, typically every 6 to 12 months. The unit is factory calibrated before delivery. Optional calibration service can be arranged.

Q7: Are consumables or spare parts universal?

A: Calibration standards, lamps and standard spare parts are available through our channel. No proprietary consumables are required. Provide the model and serial number when ordering.

Q8: Can the spectrophotometer be customised?

A: Yes, options include different measurement geometries, software modules, sample holders and data interfaces. We confirm each option before order confirmation.

Q9: Is installation and commissioning included?

A: The unit is commissioned by following the manual, including electrical checks, calibration verification and a test measurement. Remote guidance is available during commissioning. On-site installation and training can be arranged.

Q10: What samples should not be measured in this spectrophotometer?

A: Highly corrosive, volatile or strongly textured samples require appropriate preparation and accessories. Samples must be compatible with the measurement geometry and method. Follow laboratory safety regulations.
