Seawater aquaculture high precision seawater density gauge, temperature compensated optical densitometer and salinity meter.

Color claification: Deluxe aluminum

Product features: The product is equped with a temperature compensation device, and the temperature automatic compensation range is 10 degrees C ~ 20 degrees C. The temperature compensation design is adopted to overcome the data deviation caused by temperature changes. The eyepiece is super large (1mm larger than other brands), which is convenient for users to observe. Natural water is often divided into the following four categories: Salt content is le than 1 g / kg (Jian Zuoqin) for fresh water; The salt content is between 1 and 25%. For salinized water; The salt content is between 25 and 50%. For seawater and seawater with salinity; salt content is greater than 50%. It is brine; Correction method: 1. open the cover, carefully we the prism with soft cloth. 2 - about 3 drops of the self - prepared correction liquid (distilled water), placed on the prism and gently closing the cover to avoid the bubble generation, so that the correction fluid is evenly distributed on the prism surface. 3. light the instrument to the light source or the bright spot, and the eye will observe the field of view through the eyepiece. 4. read whether the scale of the boundary line is on the left 1 and the 0 on the right. 5. do not take small screws on the left 1 or right 0 position to adjust. Clockwise direction is high regulation, anti clockwise direction is low regulation. 5. after the test is finished, open the cover plate, remove the sea water, we it clean with cloth, and cover the lid properly for safekeeping. Usage method： 1. open the cover, carefully we the prism with soft cloth. 2. take the number of drops to be measured, put it on the prism, gently close the cover plate, avoid bubbles, and make the seawater evenly distribute on the prism surface. 3. light the instrument to the light source or the bright spot, and the eye will observe the field of view through the eyepiece. 4. the calibration value of the boundary line is the concentration of the solution. 5. after the test is finished, open the cover plate, remove the sea water, we it clean with cloth, and cover the lid properly for safekeeping. Matters needing attention： 1. in the use of careful and prudent use, strictly according to the use of the instructions, no loosening of the connection of the instruments, no fall, collision, severe shock. 2. after the use is finished, it is strictly forbidden to wash directly into the water and we with clean soft cloth. For optical surfaces, it should not be scratched or scratched. 3. instruments should be kept in dry, non corrosive gas areas. 4. avoid the lo of spare parts.
