Used for the detection of feather cleanliness (transparency).

GB/T14272-2011 、 GB/T10288 、 FZ/T80001

1. Calibration height of measuring cylinder: 1m

2. Diameter: 32mm

3. Instrument Size: 210 mm x 210 mm x 1050 mm

4. Weight: 3.2kg

1. Take a 10.0 g feather pile sample from the laboratory sample and put it into a 2000 ml plastic wide mouth bottle, add 1000 ml distilled water, cover it and seal it.

Let the oscillator oscillate for 30 minutes, and the direction of oscillation is from the bottom of the bottle to the mouth of the bottle.

The filtrate is collected in a 2000 ml beaker, and the prepared sample is poured into the container of the transparency meter to gradually raise the rubber hose position.

Place the sample liquid through the hose into the calibrated cylinder, and gradually raise the liquid level from the top of the cylinder down to observe the black double cross line at the bottom, until

When it disappears, the container is moved downward slightly to reappear the double cross lines, which can be seen clearly. The scale of the liquid level on the cylinder at this time is recorded.

Transparency of sample;

2. The final result of the determination of the second sample according to the above-mentioned steps is taken as an integer of the average values of the two measurements, in millimetres and in 1000mm.

The transparency meter (diameter: 32mm) should avoid measuring the intensity of light source above 600 Ix in direct sunlight.
