Whiteness Meter

Application:
This instrument based on the principle of photoelectric effect & D65 light source (R457) and with 45/0 as a illumination condition. Meanwhile, except solution or liquid samples, this instrument can be widely measured the whiteness value of any substances. Such as: powder, board, paper, paste, sheet, clay, etc.

Features:
# Compact in size, novel in design & LCD display with suitcase package..
# Succinct operation, suitable measurement range & higher performance.
# Low daft, High Accuracy, Nice Stability ensure long-time & stable running.
# Unique positioning structure & high precision optical system effectively guarantee measuring values accuracy and repeatability.
# Lower consumption and AC & DC power supply convenience for operating outside or laboratory.
# With low voltage indication function remand of users replace battery timely. With data output interface.
