HB-211ATC Handheld Refractometer for Salinity Meter

Handheld Refractometer for Salinity meter 

Product description:

To measure the salt solution, salt food and water, the concentration of the brine, products are mainly used in all kinds of pickles, pickled vegetables, salted food, biological breeding, aquarium, saline water, and other fields. Characteristic of the two calibration can directly read the proportion of salt solution and can direct reading concentration with. For agriculture, food production and field operation of great help, the product has automatic temperature compensation function is particularly convenient for field use.

Widely used for salinity meter:

Hand Held salinity refractometer with dual specific gravity and part per thousand (0/00) scales. Designed specifically for aquariums, this unit is ideal for rapid, accurate salinity determinations. Fully automatic temperature compensation(ATC) over the range of 10° to 30°C eliminates need for temperature compensation charts. High contrast white on blue for easy readability. Includes soft-side carrying case.

Directions for use:

Using soft cloth to clean the prism and testing prism, take a few drops of solution, put it on the prism, close the cover plate, escape from bubbles, to make the solution over the surface of prism.

Put the instrument into the version of alignment or light department, eyes can observed the field through Eyepiece. Rotate eyepiece to adjust hand wheel. to make the field of view of blue and white points clear.The scale of demarcation line is the density of solution. 

Calibration and correction of temperature:

It must revise Zero before measure.First,take few drops of distilled water,put it on the detection prism,and then screw the bolt of Zero so that make it reach 0%,Second,clean the detection prism to inspection.Some models of instruments have to take place standard liquids of distilled water to revise.

 Precautions & Maintain: 

(1)After using, please do not use the tap water to clean directly; Otherwise the water may go into the pipe of optical system.

(2)When using or maintaining, please handle with care and keep the surface of optical parts away from scratch or damage.

(3)The instrument can only be stored in the environment where is dry, free of dirt and contaminative gas; otherwise the optical part will get corrosion.
