Hydrometer. Concentration meter. The basic parameters of refractometer:?
? Measurement: 0 - 80% W/W
Minimum scale value: 1%
Size weight: 160x 40 - Phi Phi 30mm, 180g
Hydrometer. Concentration meter refractometer principle:
Light by two different density of medium for different propagation velocity, refracted in the interface, using the refractometer refractive prism between the sample and the sample concentration rate difference judgment.
Hydrometer. Concentration meter. The scope of application of refractometer:
Products used in food industry, aquaculture, automobile repair, batteries and other industries. And called, salinity concentration meter, OE meter, milk sugar meter, urinometer, serum protein, antifreeze, honey cryoscope concentration meter, mine emulsion concentration meter, cutting fluid concentration meter, alcohol concentration meter, Soybean Milk concentration meter etc..
?
Hydrometer. Concentration meter refractometer characteristics:
The device is compact and convenient, the instrument is easy to operate, stable and durable
???
Hydrometer. Concentration meter refractometer structure:
The 1. prism 2. detection prism 3. seat cover 4. adjustment screw 5. barrel and handle 6. diopter adjustment handwheel 7. eyepiece
Hydrometer. Concentration meter. Usage refractometer:
1. open the cover, with a soft cloth carefully wipe detection prism.
2. take a few drops of the solution to be tested, in the detection of prism, gently close the cover, to avoid bubbles, the solution over the surface of the prism.
3. the instrument into the plate alignment light or bright eyes, viewing through the eyepiece and eyepiece adjusting hand wheel rotation,
4. the field of blue and white and clear boundaries. The scale boundary value is the concentration of the solution.
PS: Correction and temperature correction
20 degrees in the environment, needs to be corrected before measuring instrument. Take the standard drops, smear on the blue detection prism, and then put the standard pieces of glass surface cover above, screw the zero adjustment screw, so that the line to dial 78.8% position. Clean the prism can be detected after detection.
If the measured temperature is higher or lower than 20 DEG C, the temperature correction table, numerical read at ambient temperature (plus or minus) temperature correction, accurate numerical. Schedule: Brix readings of temperature correction table.
Matters needing attention：
This is precision optical instruments, in the use and maintenance should pay attention to the following matters:
1. in use must be careful, strictly according to the instructions, shall not be any loose instruments each connecting part shall not fall, collision, no occurrence of severe vibration.
2. after use, is strictly prohibited directly into the water to clean, use a clean soft cloth, the optical surface should not be bumps, scratches.
3. the instrument should be placed in a dry, non corrosive gas storage places.
4. to avoid the loss of spare parts.
