OPTIZEN Alpha is a double-beam spectrophotometer, Made in Korea

Product infomation:

The previous single beam type spectrophotometer has a weak point of error occurrence in measuring a sample, because of the movement of a light source by a time lag in measuring the strength of between a reference light and a light from the sample.
