Description
Overview
GAOTek digital spectrophotometer colorimeter is the new model of bench-top spectrophotometer. It is an all-in-one model and can measure both reflectance and transmittance. It can measure both opaque and transparent materials such as paint, textile, plastic, master batches, printing materials, glasses, liquid and powder materials, etc.
Features
- Instrument adopts xenon lamp
- It can measure both reflectance and transmittance
- Auto temperature and humidity compensation function
- 4 kinds of UV modes for choices
- 4 test apertures as standard accessories, auto aperture size recognition
- 10 million samples storage memory
- Instrument is with camera to view the measurement area
- Vertical and horizontal measurement for testing different kinds of samples
