Lu Hengsheng matter measuring salinity with a hydrometer handheld meter + 0-10% precision alkalinity meter 0 ...

The Company is a manufacturer direct export hardcover type refractometer, large distribution please call or click Want advice. Product Name: salinity meter refractometer depending on the concentration of the liquid concrete has a different refractive index, the principles of design, is the use of light to try the test liquid instruments. First, the characteristics and uses of the refractometer line of precision optical instruments, fast and easy with the use of accurate measurement, light weight, small size, etc., the instrument can accurately determine the percentage of salt contained in the solution concentration, for food, agriculture and scientific research Second industry, the main technical data salinity measurement (NaCl): Measuring range: 0-100 ‰ Minimum scale: 1 ‰ Specific gravity: 1.000-1.070 Instrument size: 40 * 40 * 200 mm 2 Third, part of the instrument 1, the refractive index of the prism 2, into the light board 3, reference correction screw 4, the rubber sleeve 5, adjust the eyepiece (sharpness) use of methods: 1) the alignment of light refraction prism direction, adjust the eyepiece diopter ring until the reticle clear so far; 2) adjusting the reference: first the standard solution prior to assay (purified water), instrument and liquid to be measured based on the same temperature. Open the cover, and then take 1 to 2 drops of standard liquid droplets on the refractive prism, and gently press the cover draw a dividing line between light and shade. Rotational alignment screws so that the eyepiece of light and shade boundary coincides with the reference line (0%); honey dedicated except Note: The optical instrument factory calibration, and can be used directly. 3) open the cover, wipe the prism surface with a soft cloth, take 1 to 2 drops of the test solution was dropped on the refractive index of the prism, Close the lid gently press the relative scale of light and dark to read the line, namely the test concentration and density of liquids. 4) After measurement, direct the prism surface wipe with a damp cloth and attachments on the cover, to be dried and properly stored. V. Notes and maintenance: 1) After use, rinse with tap water directly prohibited, to avoid the optical system piping water 2) in the use and maintenance should be gently, meticulously maintained, the optical parts of the surface should not be bumps draw injury; 3) The instrument should be dry, clean, non-corrosive gas environment preservation in order to avoid parts of the surface of the optical mold; 4) in contact with the measured object prism is a consumable, can not be repaired, please be understanding; 5 ) The user must comply with the use of methods, such as damage is not covered under warranty, do not be warranty. Sixth, the instrument installed in a dedicated box, Annex 1, manual; 2, screwdriver; 3, straw; 4, flannel. Service: 陆恒生 matter if those who support the purchase of equipment warranty for one year, after product purchase, such as what problems can always phone or Want linked encountered during testing.
