Warming handheld refractometer antifreeze freezing battery hydrometer liquid glass cleaner water freezing point tester handheld refractometer antifreeze tester freezing water battery hydrometer automotive antifreeze coolant freezing water meter battery hydrometer propylene glycol antifreeze freezing point tester refractometer Product Description: antifreeze freezing point and battery fluid tester is based on the proportion of dual-use solution concentration (corresponding with the freezing point) correspondence between the refractive index and optical instruments designed. The instrument can quickly test and measurement of ethylene glycol and crystalline cell freezing water propylene glycol based antifreeze gravity (relative density). Can also be used for cooling water, refrigerant liquid for automobile antifreeze and the like. Antifreeze freezing point detection with refractometer is used to measure both ethylene and propylene glycol-based automotive cooling systems and window cleaning solution in the freezing temperature, it can check the specific gravity of the electrolyte in the battery and use. Freezing water cooling system calibrated in degrees Celsius. Zero calibration: 20 ° C with distilled water at 20 ° C calibration environment. Product Specifications: Model: HT414ATC antifreeze freezing point Measuring range: antifreeze freezing EG -50 ~ 0 ℃ (ethylene glycol) antifreeze freezing PG -50 ~ 0 ℃ (propylene glycol) chemical cleaning agents C -40 ℃ ~ 0 ℃ Battery Liquid B 1.1 ~ 1.4kg / L smallest scale: 1 ℃ antifreeze cleaner 5 ℃ battery fluid 0.01kg / L Dimensions (mm): 30 * 40 * 160 Weight (g): 205 with automatic temperature compensation Automatic temperature compensation: 0 -30 ℃ Packing List on handheld refractometer: 1, a 2 refractometer, a manual 3, screwdriver a 4, a 5 straw, a 6 glasses cloth, a sponge packaging, the main technical parameters: 1) the main types: Brix meter, salinity meter, alcohol concentration meter, industrial concentration meter, cutting fluids, honey, milk, soybean milk, etc; in terms of products, service facility commitment free replacement within six months, 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.
