CS-810 Transmittance Spectrophotometer

CS-810 transmittance spectrophotometer is good performance and specially designed for testing the transparent material's transmittance, APHA/Pt-Co/Hazen, Gardner, ASTM color, chromatic value,etc.

Transmittance spectrophotometer CS-810 adopts the geometry of D/0, integration of the full band LED composite light source, double beam optical system, ETC every-test calibration technology, which makes the instrument reaches a resolution of 0.0001, deviation of the transmittance within 0.08% and chromatic value △E*ab 0.015.

Brief Introduction

1. D\0 Geometry

liquid color control

2. It is suitable for testing the clear, transparent and translucent products such as glass,oil,plastic,petrol,gasoline and other materials' color.

6.Longest Warranty Time

liquid color control

a. One Year Guarantee Time.

b. If testing data is not correct, we can do refund.

c. We will provide testing report for every device to assure the authority of the data and it will save the calibration cost for 1 year.
