Medical refractometer urine concentrations of serum protein detector hydrometer medical urinometer / serum protein Medical Warming handheld refractometer urine specific gravity refractometer handheld refractometer serum protein Warming Product Description: Medical refractometer, urine specific gravity / serum protein refractometer can quickly and accurately measure the levels of human and animal physiological fluid, three scales were measured specific gravity, serum protein and refractive index. The product is simple in structure, easy to carry and operate, clear vision, hospitals, research institutes and veterinary industries indispensable testing equipment. Product Details; Model: HT-311ATC medical urinometer measuring range: 0 ~ 12g / dl serum protein specific gravity 1.000 ~ 1.050sg smallest scale: 0.2g / dl serum protein 0.0002sg specific gravity Dimensions (mm): 30 * 40 * 170 Weight (g): 215 Automatic temperature compensation: 0-30 ℃ on handheld refractometer packing list: 1, refractometer a two, a three-manual, screwdriver a 4, a 5 straw, a 6 glasses cloth, sponge packaging First, the main technical parameters: 1) the main types: sugar meter, salinity meter, alcohol concentration meter, industrial concentration meter, cutting fluids, honey, milk, soybean milk, etc; in terms of products, service facility within six months commitment free replacement, one year free warranty. 2) measuring range and minimum scale :( See detailed parameters of each series) with temperature compensation function, making the data more accurate 4) eyepiece has been upgraded, with greater clarity, reduce fatigue observer. Second, product application : handheld refractometer has a simple structure shockproof, easy to operate portable, clear vision, and low cost advantages. Sugar Series Application in canned food, fruit juice manufacturing, wine fermentation, beverages, fruits, honey harvesting and other fields. Salt Series Applications in the field of aquaculture, aquarium, saline preparation and so on. Serum protein, urine specific gravity testing medical series applications. Industrial Series Application Detection car battery fluid, coolant, cleaning fluid, machine lubrication, coolant testing. Series of alcohol used in liquor, wine alcohol concentration testing (ethylene glycol). Soy milk, soy milk is used to control the taste of the series as well as sweetness, is an essential tool for soybean processing industry and canteens, milk factory, hotel restaurant. Third, use the reference product :( chart) 1) The light refraction prism alignment direction ⑥ eyepiece diopter adjustment ring until the reticle clear up; 2) adjusting the reference (low range): first the standard solution before measurement ( pure water), based on the same instruments and test liquid temperature. Opened the lid, and then take 1 to 2 drops of liquid droplets on a standard refractive prism, and gently press the cover draw a dividing line between light and dark. Calibration screw rotating eyepiece field of view so that shading boundary coincides with the baseline (0%); high range instrument calibration, must comply with the standard blocks, carried out under the manufacturer's instructions Note: The optical instrument factory adjusted well. directly, without calibration. 3) opened ③ cover, wipe with a soft cloth ② prism surface, take 1 to 2 drops of test solution was dropped on the refractive prism ②, Close the lid gently press until no bubbles. The alignment of the light refraction prism direction, light and dark to read the line from ⑦ eyepiece (see scale diagram of an example) relative scale, that is, the value of the measured concentration and density of the liquid. 4) After measurement, direct the prism surface with a damp cloth and wipe the attachments on the cover, to be dry and properly stored. Fourth, our advantage: Our factory is specialized in wholesale sales of laboratory equipment company, the sales of refractometers or replacement warranty for 2 years, the company has a lot of cash. Welcome to call us, to discuss cooperation! A specialized laboratory equipment production, sales, after-sale guarantee; Second factory direct, affordable, quality of products have been tested; Third All products received have quality problems package returned (return postage sellers bear) within 3 days; four. 1 month replacement (shipping sellers bear) 1 year warranty (quality problems shipping sellers bear); maintenance of life! Five, precautions and maintenance: 1) After use, rinse with tap water directly prohibited, to avoid optical system piping water; 2) in the use and maintenance should be gently, careful maintenance, optical parts of the surface should not be bumps scratch; 3) The instrument should be dry, clean, non-corrosive gas environment preservation in order to avoid the optical parts of the surface mold; 4) in contact with the measured prism is a consumable, can not be repaired, please be understanding; 5) You must comply with the use of methods, such as causing internal damage not covered under warranty, the warranty does not give warranty period 6): two-year product repair, maintenance of life.
