Whiteness Meter

PCE-WNM 100

INSTRUCTION MANUAL

1. APPLICATIONS & FEATURES

* Whiteness Meter is mainly used to

directly measure the whiteness value of

object or powder with at surface.

Can be widely used in whiteness

measurement of textile printing and

dyeing, paint, chemical building

materials, paper board, plastic products,

white cement, ceramics, enamel, talc

powder, starch, our, salt, detergent,

cosmetics and other substances.

* It consists of Light Source, Optical

System, Detection System, Data Process

and Display System. The whiteness

Calculation Formula of the instrument is

blue light whiteness R457.

* Use of high quality imported components,

good reliability.

* Pass strict inspection and testing, the

instrument conforms to the JJG 512-

2002 Whiteness Meter Verification

Regulation. Also conforms to GB3978,

GB3979, GB7973, GB7974, ISO2470,

and other standards.

zeroing operation amplier, inputted to

the calibration circuit for energy

calibration. Then, the whiteness value of

the sample is directly shown on the digital

display.

3. NOTE

This instrument is

metrological

appliance, is strictly forbidden to

disassemble, please read the instructions

carefully before use.

measurement data.

* There should be no corrosive gas or

vibration source in the operating

environment.

* Use USB data output and RS-232 data

output to connect with PC.

* Provide Bluetooth data output choice.

2. OPERATING PRINCIPLE

* There should be no light exposure and

magnetic eld interference.

* The ambient air should be dry and no

dust, etc.

The light source of the instrument is long-

life LED with 457nm, conforming to the

light source requirement in the JJG 512-

2002 National Metrological Whiteness

Meter Verication Regulation.

* If the instrument is not to be used for any

extended period, remove batteries to

prevent battery leakage corroding

internal circuit.

* The optical path design is reasonable,

simple. Adopt lter system with

correction, the whiteness can be

reected quantitatively.

The measurement of the instrument adopts

the principle of photoelectric eect. The

diuse reectance Radiant Brightness

is amplied by high-precision auto

* To keep the measuring sensor clean, not

to touch the optical element with hand,

so as not to aect the spectral

characteristics.

N o p r e h e a t i n g a f t e r s t a r t i n g ,

measurements can be taken after simple

calibration, easy to operate.
