Specifications:

MN-B Reflectometer is a highly sensitive reflectance measuring instrument used to measure the black and dark gray objects on the surface of the black level of the instrument's measurement accuracy and the United States test,Astm ) Specified Densichon Type reflection photometer has a good correlation.The instrument measuring circuit selection of high precision, low drift integrated operational amplifier and large scale integrated circuit A / d Converter, so the instrument readings stable, reliable, easy to use.

Mainly used:

Determination of color strength and blackness of carbon in ink coatings, carbon black and rubber industry.

Features:

1.Small size, light weight, the real portable machine.

2.Power, peace of mind, high efficiency, a battery can continue to use 60Hour measurement of nearly ten thousand data.

3.High stability, that is, that is measured immediately.

4.Quartz Crystal Standard Edition, the annual rate of change is very low.

5.LED Long life light source.

6.Automatic shutdown, saving power, to avoid battery flow leading to failure.

7.An optional powder sample box and pressure gauge for accurate powder measurement.

8.Standard gray scale transmission standard value, accurate and reliable.

Specifications:

1.parameter (unit%)

2.Projection angle: 45/0

3.Operating voltage: section 5number (AA)Dry battery can be.1.5v)

4.Window size: 12 × 26mm

5.Host size: 114 × 32 × 64mm (Length × width × height)

6.Instrument weight: 300g

Instructions for use:

1. Power on: press the switch button on the right side of the instrument, the LCD display readings, indicating that the power has been connected, the instrument began to work.
2. Calibration: open the standard box, the side of the instrument measuring port on the gray ceramic standard board.Adjust the calibration knob above the instrument, so that the display reads the standard board calibration value.
3. Measurement: the instrument flat placed on the surface of the measured object, showing the value of the measured object is the black value.
4. Shutdown: Press the switch button on the right side of the instrument to shutdown.

Precautions:

1. Use of direct sunlight should be avoided, otherwise the impact of measurement accuracy.
2. The measurement surface of the sample, if there is not uniform or horizontal, longitudinal texture of the difference, you can choose in different places and different angles for multiple measurements, averaged to indicate the value of its blackness.
3. For transparent objects, to take a number of overlapping layers, so that opaque.
4. For powder or small granular samples, the need to match my company to provide constant pressure powder sampler for measurement, the use of pressure sampling method see appendix.

Instrument maintenance:

1The instrument should be kept clean, do not touch the surface with the fingers, such as the surface stains, will lead to increased error and inaccurate instrumentation can be used lens paper or cotton swab dipped in a little alcohol wipe.

2Because of the high stability of the instrument, the instrument does not have to be calibrated frequently 2After an hour, and then re-calibration time.

3When the instrument is in use, measure it vertically to avoid dust, especially when measuring powder samples, and dust contaminating the lens.

4The instrument is designed for extremely high battery usage when the battery is used 0.8V(The battery power is exhausted), the instrument readings begin to fall, the red LED on the upper right corner of the instrument display light, prompt the operator need to replace the battery. Open the left battery cover, remove the old battery, replace the new battery, negative Facing the inside, the positive side facing outward, and closing the battery cover, the instrument can be reused.

5Do not use fake batteries, may cause liquid flow, damage to the machine.
