digital refractometer
DBR portable digital
refractometer is a product of precise optical cells, digital picture processing
technique and accurate temperature compensation. Microprecessor is centre of
the refractometer. Measurements are precisely displayed by three and half
figures number liquid crystal displayer. The refractometer is simple to operate
and easy to carry. It has accurate measurements, complete functions and Its
battery can serve long.
（1） features:
* Precise optical
cells and intelligent digital picture processing technique insure accurate and
stable measurement.
* Accurate
temperature compensation insure exact revision in wide range of measuring
temperature.
* Low power
consumption circuit design, intelligent power management and automatic switch
off can save the power and lengthen battery’s service life.
* The
refractometer can give an alarm when low voltage happens.
* Centigrade
degree and Fahrenheit degree can be transformed.
* Operating four
buttons can fulfil whole process.
* Three and half
figures number liquid crystal displayer can display various measuring
parameters and the state of service.
* Circuit without
adjustable cells along with SMT and waterproofness make the product have strong
shock absorption, high consistency and reliability.
